Installation

phpMyAdmin does not apply an≈®★≠y special security methods≈ ÷≤ to the MySQL database server. It©σ is still the system adminδφ ♦istrator’s job to grant permissions on the MySQ✘←≥∑L databases properly. phpMyAdmin’s Users page can be used for this.

Linux distributions

phpMyAdmin is included in most Linux×πΩπ distributions. It is reγ÷π✘commended to use distribution paΩ♦>ckages when possible - they®‍∞‍ usually provide integration to your distribution $♣↔ and you will automatically get security update₩≥¶s from your distribution.

Debian and Ubuntu

Most Debian and Ubun>←§tu versions include a phpMyAdmin p©φ≠ackage, but be aware ∑δδ♣that the configuration file is maintained in&₩ /etc/phpmyadmin and may differ in som≠ <e ways from the official phpMyAdmin document₩¥ ↑ation. Specifically, it do<✘φes:

More specific details a∑α≠ bout installing Debian or Ubuntu γΩ packages are available♠♠ in our wiki.

See also

More information can be found in README.Debian (it is installed as /usr/share/doc/phpmyadmin/README.Debian with the package).

OpenSUSE

OpenSUSE already comes with phpMyAdmin γ♥package, just install pac¶‍kages from the openSUSE Build Servi •×ce.

Gentoo

Gentoo ships the phpMyAdmin pack$₩§♣age, both in a near-stock configuratioΩΩ$n as well as in a webapp-config configuration. Use emerge dev-db/phpmyadmin to install.

Mandriva

Mandriva ships the phpMyAdmin pack↕↕age in their contrib branch and can be installed via the usual Contr×₩↓ol Center.

Fedora

Fedora ships the phpM‍↓yAdmin package, but be awarε£e that the configuration file is mai$♣ntained in /etc/phpMyAdmin/ and may differ in some ways f×←÷§rom the official phpMyAdmin dδ ÷¶ocumentation.

Red Hat Enterprise Linux

Red Hat Enterprise Linux i≤☆tself and thus derivatives likeφ© CentOS don’t ship php>★™MyAdmin, but the Fedora-driven rep₹✔↓ository Extra Packages for Enterpris♠"✔e Linux (EPEL) is doing so, if it’s enabled. But be aware that the configura•'tion file is maintained in /etc/phpMyAdmin/ and may differ in some way&λ>s from the official phpMy÷β£Admin documentation.  ¥

Installing on Windows

The easiest way to get phpMyAdmin on ®©≤Windows is using third party↑↔ products which include phpMyAdmin tog₹&★≤ether with a database and w★§≠eb server such as XAMPP.

You can find more of such options★∏>× at Wikipedia.

Installing from Git

In order to install from Git, you’ll ↔$αneed a few supporting ¶£∏βapplications:

  • Git to download the source, or you ca¶γ‌n download the most recent δ"↓ source directly from Github

  • Composer

  • Node.js (version 10 or higher)

  • Yarn

You can clone curren εt phpMyAdmin source from https://github.com/phpmyadmin/phpmyadmin.git:

git clone https://github."→com/phpmyadmin/phpmyadmin.git

Additionally you need to install dγβ ®ependencies using Composer:

composer update

If you do not intend to develop, you ca♦σ≤n skip the installat©₹ion of developer tools by invoking:

composer update --no-dev

Finally, you’ll need to use Yarn to install some JavaScript dependencie♠§≥∏s:

yarn install --product¶σion

Installing using Composer∏₽∏≥

You can install phpMyAdmin usi±πλ≈ng the Composer tool, since 4.7.0 the release↕✔s are automatically mirrored to th‌®σ​e default Packagist repository.

Note

The content of the Compos •≥er repository is automaticall±↕y generated separately from the releases, so"£ the content doesn’t have to be 100% same as©¶ when you download the tarball. There s<¥hould be no functional differences though.

To install phpMyAdmin simply run:

composer create-project phpm≥★πyadmin/phpmyadmin

Alternatively you can us≠ ←e our own composer repository, which∑←♣™ contains the release tarballs an×✔↑₽d is available at <https://www.phpmyadmin.net/package㮥♣s.json>:

composer create-project ph♠σpmyadmin/phpmyadmin --repository-url=https://www.phpmyadmin.net/pa≥ γφckages.json --no-dev

Installing using Docker

phpMyAdmin comes with a Docker official image, which you can easily deploy. You can d∏←≤←ownload it using:

docker pull phpmyadmin

The phpMyAdmin server wi✔&>ll listen on port 80. It su≥ €pports several ways of configuring the link to λ♣βthe database server, ei★↔ther by Docker’s link feature by linking your → ↔database container to db for phpMyAdmin (by specifying --link your_db_host:db) or by environment variables (in this case ±‍✘φit’s up to you to set up networking in Docker to ↓≈♣allow the phpMyAdmin conta∑♠iner to access the database coεβ ×ntainer over the network).

Docker environment variables

You can configure several phpMyAdmin featu≥  res using environment variables:

PMA_ARBITRARY

Allows you to enter a database serv₹→≠er hostname on login form.

PMA_HOST

Hostname or IP address of th$λ♠e database server to use.

PMA_HOSTS

Comma-separated hostnames or IP add‌ε resses of the database servers to use.

Note

Used only if PMA_HOST is empty.

PMA_VERBOSE

Verbose name of the database server.

PMA_VERBOSES

Comma-separated verbose name of the databa  se servers.

Note

Used only if PMA_VERBOSE is empty.

PMA_USER

User name to use for Config authentication mode.

PMA_PASSWORD

Password to use for Config authentication mode.

PMA_PORT

Port of the database server to us₩£&e.

PMA_PORTS

Comma-separated ports of the datab★¥​✔ase server to use.

Note

Used only if PMA_PORT is empty.

PMA_ABSOLUTE_URI

The fully-qualified path (https://pma.example.net/) where the reverse proxy mak★®©λes phpMyAdmin available.

HIDE_PHP_VERSION

If defined, this option will πΩ'hide the PHP version (expose_php = Off). Set to any value (such as HIDE_PHP_VERSION=true).

UPLOAD_LIMIT

If set, this option will override t✔↑↕₹he default value for apache and php-fpm (this wi™"ll change upload_max_filesize and post_max_size values).

Note

Format as [0-9+](K,M,G) default value is 2048K

PMA_CONFIG_BASE64

If set, this option will override th©×£↓e default config.inc.php with the base64 deco≥₩₽ded contents of the variab¶•le.

PMA_USER_CONFIG_BASE64

If set, this option will overrid€βe the default config.user.inc.php with the base64 decoded contents ofλδα₽ the variable.

By default, Cookie authentication mode is used, but if PMA_USER and PMA_PASSWORD are set, it is switched to Config authentication mode.

Note

The credentials you need to log in ‍↕>are stored in the MySQL server, in c±↓ase of Docker image, there are various ways $‌₹₹to set it (for example MYSQL_ROOT_PASSWORD when starting the MySQL ' ♣container). Please chec↑Ω"k documentation for MariaDB container or MySQL container.

Customizing configuratioπ¶n

Additionally configuration can beλ€ tweaked by /etc/phpmyadmin/config.user.inc.php. If this file exists, it will be loaded after "λ¶configuration is generated from above environment™±• variables, so you can override any configur±→>ation variable. This conf₹≠‌iguration can be added as a volume ¶'∑ when invoking docker using -v /some/local/directo©‌★★ry/config.user.inc.php:/etc/phpmyad•π‍÷min/config.user.inc.php parameters.

Note that the supplied c♦₩ onfiguration file is applied after Docker environment variables​λ, but you can override any of tδ©'‌he values.

For example to change the ↑≥±¥default behavior of CSV export you can use the↓☆✔✔ following configuration file:

<?php
$cfg['Export']['csv_columns'] = true;

You can also use it to define server configur‌★"ation instead of using t↓✔σhe environment variabl$ βes listed in Docker environment vari∏π₽ables:

<?php
/* Override Servers array */
$cfg['Servers'] = [
    1 => [
        'auth_type' => 'cookie',
        'host' => 'mydb1',
        'port' => 3306,
        'verbose' => 'Verbose name 1'•β;,
    ],
    2 => [
        'auth_type' => 'cookie',
        'host' => 'mydb2',
        'port' => 3306,
        'verbose' => 'Verbose name 2 ₹9;,
    ],
];

See Configuration for detailed descript•δion of configuration options.

Docker Volumes

You can use the following volu©∑σmes to customize image behavio<♣r:

/etc/phpmyadmin/config.user.inc.ph☆♥★≤p

Can be used for additional sett©  ings, see the previous chapte™∑ r for more details.

/sessions/

Directory where PHP sessions are stored. You mighφ‍​t want to share this for example when using∞≤≠ Signon authentication mode.

/www/themes/

Directory where phpMyAdmin looks fo↑♥•↕r themes. By default onl≥₩×y those shipped with php™ MyAdmin are included, but you can​®∞ include additional phpMyAdmin themes♠↑∏↔ (see Custom Themes) by using Docker volumes.

Docker Examples

To connect phpMyAdmin to a given serve♣β≠&r use:

docker run --name myadmin -d -e≥φ÷ PMA_HOST=dbhost -p 8080:80 phpmyadmin/phpmyadmin

To connect phpMyAdmin to more ' servers use:

docker run --name myadmin -d -e PMA_HOSTS=dbhost1,dbhost2,dbhost3 -p 8080:80 phpmyadmin/phpmyadmin

To use arbitrary server option:

docker run --name myadmin -d --lin→₩≤φk mysql_db_server:db -p 8080:80 -e PMA_ARBITRARY=1 phpmyadmin/phpmyadmin

You can also link the database contaδ≈iner using Docker:

docker run --name phpmyadmi→≥♠n -d --link mysql_db_server:db -p 8080:80 phpmyadmin/phpmyadmin

Running with additional configuration:

docker run --name phpmyadmin -•←d --link mysql_db_se✔"↕ rver:db -p 8080:80 -v /some/local/directory/config.σ →↑user.inc.php:/etc/phpmyadmin/config.user.in•∏♠c.php phpmyadmin/phpmδ♣✘♠yadmin

Running with additional themes:

docker run --name phpmyadmin -♥φ♥ d --link mysql_db_server≥&≈:db -p 8080:80 -v /custom/phpmyadmin/theme/:α≈π/www/themes/theme/ phpmyadmi ​n/phpmyadmin

Using docker-compose

Alternatively, you can also uβ​se docker-compose with the docker-compose.ym™π÷βl from <https://github.com/phpmyadmin/docker>. This will run ph&÷ ​pMyAdmin with an arbitrary se‍₽←‌rver - allowing you t©↓∑o specify MySQL/MariaDB server on t≥‌he login page.

docker-compose up -d

Customizing configurati β>on file using docker-compose

You can use an extern&™₹♣al file to customize phpMyAd>&&♦min configuration and pass it usin≤₽ ¥g the volumes directive:

phpmyadmin:
    image: phpmyadmin/phpmyadmin> 
    container_name: phpmyadmin
    environment:
     - PMA_ARBITRARY=1
    restart: always
    ports:
     - 8080:80
    volumes:
     - /sessions
     - ~/docker/phpmyadmin/config.user.inc.p∏<♦£hp:/etc/phpmyadmin/config‍™©♣.user.inc.php
     - /custom/phpmyadmin/theme/:/www/themes/themφ>×e/

Running behind haproxy in a subdirec®‌‍tory

When you want to expose phpMyAdmin ∞≤♥running in a Docker container in a$&& subdirectory, you need t₩≠o rewrite the request path€"γ£ in the server proxy×→π→ing the requests.

For example, using haprox★↕'±y it can be done as:

frontend http
    bind *:80
    option for≥×✔✔wardfor
    option http-serveσ<r-close

    ### NETWORK res‍ $triction
    acl LOCALNET  src 10.0.0.0/8 19 ≥₹©2.168.0.0/16 172.16.0.0/12

    # /phpm☆α£→yadmin
    acl phpmyadmin  ©$®path_dir /phpmyadmin
    use_backend phpβ≥‍myadmin if phpmyadmin LOCALNET

backend phpmya✔"dmin
    mode http

    reqirep  ^(GET|POST|HEAD₽¥)\ /phpmyadmin/(.*)     \←✔™1\ /\2

    # phpMyAdmin∞>β container IP
    serve←γ≤ r localhost     172.3βα¶♠0.21.21:80

When using traefik, something like ∞✘"↓following should work:

defaultEntryPoints = [&∞∏≥quot;http"]
[en₹ tryPoints]
  [entryPoints.http]
  address = &quo∞↑✔→t;:80"
    [entryPoints.http.redirect]
§↔↑♦      regex = "(http:\\β /\\/[^\\/]+\\/([^\\?\\.]+)['©∏^\\/])$"
      replace✘β←ment = "$1/"

[backends]< 
  [backends.myadmin]
    [backend↔×s.myadmin.servers.myadmin]
    url="h→‌π☆ttp://internal.address.to.pma"

[frontends]γ₩<€
   [frontends.myadmin]
   backend = "myφ₹admin"
   passHostHeade♠‍↓r = true
     [frontends.myadmin.routes.d↔★‍efault]
     rule="↓♠•₩;PathPrefixStrip:/phpmyadmin/∞✔∏♠;AddPrefix:/"

You then should specify PMA_ABSOLUTE_URI in the docker-compose configuration:

version: '2'

services:
  phpmyadmin:
    restart: always
    image: phpmyadmin/phpmyadmin
    container_name: phpmyadmin
    hostname: phpmyadmin
    domainname: example.com
    ports:
      - 8000:80
    environment:
      - PMA_HOSTS=172.26.36.7,172.26.3λ§♠6.8,172.26.36.9,172.26.36.λ≤≥10
      - PMA_VERBOSES=product'©ion-db1,production-db2,dev-db1,dev-db2
      - PMA_USER=root
      - PMA_PASSWORD=
      - PMA_ABSOLUTE_URI=http://exampl✘≈αe.com/phpmyadmin/

IBM Cloud

One of our users has created a helpful gu€σ∏ide for installing phpMyAdmin on the IBM Cloud platform.

Quick Install

  1. Choose an appropriate distribution kit from✘♦ the phpmyadmin.net Downloads page. Some kits  λ§∞contain only the Engl ₽•πish messages, others con​×≤tain all languages. We’ll assume you chose ®π×a kit whose name look±×s like phpMyAdmin-x.x.x -all-languages.tar.gz.

  2. Ensure you have downloaded a genuine archi↔£÷ve, see Verifying phpMyAdmin releases→↕€γ.

  3. Untar or unzip the distribution (be sure to unzλשip the subdirectories): tar -xzvf phpMyAdmin_x.x.x-allε•±-languages.tar.gz in your webserver’s document root. If you don’t h↕♥£ave direct access to your document root, put ↓α™the files in a directory on your local machi §→§ne, and, after step 4, transfer the directory " ™∞on your web server using, for example, ÷αFTP.

  4. Ensure that all the scripts hav✘✘•<e the appropriate owner ≥☆(if PHP is running in safe mode, having s✘↕​♠ome scripts with an owner different fro§γ‍m the owner of other scripts will be a pβ♦™ roblem). See 4.2 What’s the preferred way of ↕≈↔®making phpMyAdmin secure σ ↑☆against evil access? and 1.26 I just installed ¶πphpMyAdmin in my documentΩ→♦ root of IIS but I get the err♣÷↔or “No input file specified” when trying to r★"un phpMyAdmin. for suggestions.

  5. Now you must configure your installation. Ther  ‌λe are two methods that can be used.™₽ Traditionally, user↓±s have hand-edited a copy of config.inc.php, but now a wizard-style setup scrip♣αt is provided for those who prefer a graphicaβ$•αl installation. Creating a config.inc.php is still a quick way t€∏®o get started and needed for some advan ♥♥≤ced features.

Manually creating th≠∏¥e file

To manually create t•→he file, simply use your text editor to c©∑reate the file config.inc.php (you can copy config.sample.inc.ph§& p to get a minimal confi©♦≠guration file) in the main (top∏↔∏α-level) phpMyAdmin directory (§♥the one that contains→×★ index.php). phpMyAdmin first loads the default<'✘ configuration values an♠★d then overrides those val‍<ues with anything found in config.inc.php. If the default val≥↕ue is okay for a particular settin"≤g, there is no need to include iβ♥t in config.inc.php. You’ll probably need onl∞€±y a few directives to get going; a'★∏  simple configuration may look like thiδ¥↕s:

<?php
// use here a value of your choice at l<>east 32 chars long
$cfg['blowfish_secret♥→φ'] = '1{dd0`<Q),5XP_:R9UK%%8\"EEcyH#{o↕×♣←9;;

$i=0;
$i++;
$cfg['Servers'][$i]['auth_type']     = 'cookie';
// if you insist on "root&q♦×"±uot; having no passwor↕'↔d:
// $cfg['Servers&#↓©'↑39;][$i]['AllowNoPa∑←ssword'] = true;

Or, if you prefer to not be prompted every t↓γφ¶ime you log in:

<?php

$i=0;
$i++;
$cfg['Servers'][$i]['user']          = 'root';
$cfg['Servers'][$i]['password']      = 'changeme'; // use here your password
$cfg['Servers'][$i]['auth_type']     = 'config';

Warning

Storing passwords in the configuration‌✘&$ is insecure as anybody can then >•€manipulate your databas✘ ↔¥e.

For a full explanation of possible configur♠φ§φation values, see the"✔<¶ Configuration of this document.

Using the Setup script

Instead of manually editing config.inc.php, you can use phpMyAdβΩ©φmin’s setup feature. The file can be ge©∑nerated using the setup and you can ₩₩ download it for upload to the↑€ server.

Next, open your browser and visit the locatiΩ$​on where you installed phpMyAdmin, wi✔§↑th the /setup suffix. The changes are ←±∏♠not saved to the server, you need to use the Download button to save them to yoγ÷ur computer and then up÷→♥load to the server.

Now the file is ready to be use☆♣↕∏d. You can choose to r←≤‌eview or edit the file with your favorite ÷δφ₩editor, if you prefer to set some advanceδβ₹λd options that the setup sβγ₹cript does not provide.

  1. If you are using the auth_type “config”, it is suggested that you protect the ±​™πphpMyAdmin installation d<£ €irectory because using config± ‍β does not require a user to δφenter a password to access♦★α₩ the phpMyAdmin installation. Use of an alternat↕ φ₽e authentication method is reco÷ ↑>mmended, for example with ε₩≥>HTTP–AUTH in a .htaccess file or switch to using auth_type cookie or http. See the ISPs, multi-user installations for additional information, especially 4.4 phpMyAdmin always gives “Access deni'↔±ed” when using HTTP authent®λication..

  2. Open the main phpMyAdmin directory in yo≈☆±∑ur browser. phpMyAdmin should now display ' a welcome screen and your databases, or a logi'σn dialog if using HTTP or cookie authentication mode.

Setup script on Debian, Ubun×₽tu and derivatives

Debian and Ubuntu have c‌ hanged the way in wh₽♠±αich the setup script is enabled and di≥∞≥♥sabled, in a way that single command ₹←απhas to be executed for eitherφ♥ of these.

To allow editing configuration invoke:

/usr/sbin/pma-configure

To block editing configuration invokδ↓βe:

/usr/sbin/pma-secure

Setup script on openSUSEβ™↓

Some openSUSE releases do not inc÷®☆lude setup script in the packag‌↔↔>e. In case you want to generate £δ‌configuration on these you can↑↓ either download origin®Ω"πal package from <https://www.phpmyadmin.net/> or use setup script on our demo server: " <https://demo.phpmyadmin.net/mast♥≥γer/setup/>.

Verifying phpMyAdmin releases

Since July 2015 all phpMyAdmin releases are crα ¶♥yptographically signed <↔≈&by the releasing develope ←"r, who through January  ÷2016 was Marc Delisle. His key idλ≠¶ is 0xFEFC65D181AF64δ→♦β4A, his PGP fingerprint is:

436F F188 4B1A 0C3F DCBF 0D79 FEFC 65 §D1 81AF 644A

and you can get more identification inf∑♦ormation from <https://keybase.io/lem9>.

Beginning in January 2016, the release manager iλδs Isaac Bennetch. His key id is 0xCE752F178259BD♠γ←"92, and his PGP fingerprint is:

3D06 A59E CE73 0EB7 1B51 1C17δ♦♥€ CE75 2F17 8259 BD92

and you can get more identificatλ ∏∞ion information from ×☆ <https://keybase.io/ibennetch>.

Some additional downloads ∞☆(for example themes) mightσ☆ be signed by Michal  ≥→✘Čihař. His key id is 0x9C27↔‍B31342B7511D, and his PGP εα♣γfingerprint is:

63CB 1DF1 EF12 CF2A C0EE 5A≠×≠σ32 9C27 B313 42B7 511D

and you can get more identification i'✔nformation from <https://keybase.io/ni$‍≠→jel>.

You should verify tha™ ¶λt the signature matches the archive you∑≈≥ have downloaded. This‍♣‌€ way you can be sure that you are ¶‍☆using the same code that was relea£✔←≤sed. You should also verify the date of the sig‌'§nature to make sure that you downloaded t$←‍he latest version.

Each archive is accompanied by .asc files which contain the PGP signat↑≥ure for it. Once you have both of them in tλπ&he same folder, you can verify the signature:

$ gpg --verify phpMyAdmγ™×in-4.5.4.1-all-languages.zip.‍ §≥asc
gpg: Signature made Fri 2♠©↔9 Jan 2016 08:59:37 AM EST using RSA ke"•✔♦y ID 8259BD92
gpg: Can't check signature: public key not ‍←≠πfound

As you can see gpg complains that it does not k‌&≠now the public key. At this point, you should do ✔‌±one of the following&♠" steps:

$ gpg --import phpmyadmin.keyring
  • Download and import the ke& πy from one of the key servers:

$ gpg --keyserver hkp://pgp.mit.edu --re✘±cv-keys 3D06A59ECE730EB71B511C17C εE752F178259BD92
gpg: requesting key 8259BD92 from hkp £♦server pgp.mit.edu
gpg: key 8259BD92: public key "Isaac Ben δ netch <bennetch@gmail.com>" im∏δ≈ported
gpg: no ultimately trusted keys found
gpg: Total number pro‍‍cessed: 1
gpg:               importe∑$d: 1  (RSA: 1)

This will improve the situation a bi₹ ★t - at this point, you can veri‍↑φ↔fy that the signature  σ≠from the given key is correct but you ★>∞₩still can not trust the name used in t>♣≈he key:

$ gpg --verify phpMyAdmin-4.5.4.1-all-languages.zip±≥.asc
gpg: Signature made Fri 29 Jan 2016 08:59:37 £♦πAM EST using RSA key ID ≠Ω♦8259BD92

gpg: WARNING: This key is not certified ≥‌ with a trusted signature!
gpg:          There is no in→✔dication that the signature belongs to the'≥→ owner.
Primary key fingerpri₽↓nt: 3D06 A59E CE73 0EB7 1B51  1C17 CE75 2Fεε​17 8259 BD92

The problem here is that anybody could i←φΩssue the key with this name↓ ₹☆. You need to ensure that the keγ ∏y is actually owned by the mentioned person. The★★™ GNU Privacy Handbook covers this topi$®φc in the chapter Validating other keys on​φ your public keyring. The most reliable method i↓ε≤s to meet the developer in person and excha≤≥nge key fingerprints, however, y ≤←ou can also rely on the web of trus×¶₽ t. This way you can trust the key transitivelyε'© though signatures of others&δ↕∞, who have met the developer in person.

Once the key is trusted, the warnin¶•'g will not occur:

$ gpg --verify phpMyAdmin-4₹£α.5.4.1-all-languages.zip.ascλ≈
gpg: Signature made Fri 29 Jaα♠Ω↓n 2016 08:59:37 AM EST using RSA key ↑∑↔ ID 8259BD92
gpg: Good signature φ✔₽βfrom "Isaac Benn¥←<etch <bennetch@gmai↑≠l.com>" [full]

Should the signature ♠≈ αbe invalid (the archive has been changed), you w→'✔✔ould get a clear error rega≤δΩrdless of the fact that←≥φ the key is trusted or not:

$ gpg --verify phpMyAdmin-4.5.4.1-all-langua♣ ges.zip.asc

phpMyAdmin configuration π'storage

Changed in version 3.4✘×.0: Prior to phpMyAdmin 3.4.0 this was called Linkedδ¶γ Tables Infrastructure, but the name was δ×changed due to the extended scope of the stor‌♥δ<age.

For a whole set of additionaε↔l features (Bookmarks, comments, SQL-history, tracking mechanism, PDF-generation, Transformations, Relations etc.) you need to create a set of special table≠€s. Those tables can be located in your own ♥↔database, or in a central database f∞≈or a multi-user installation (this database wo₽★φ€uld then be accessed by theπΩ controluser, so no oth↓₩★ er user should have rights to←★™ it).

Zero configuration

In many cases, this database structure can b♠π§e automatically created and configured↓®'↓. This is called “Zero Configuration” ♠$mode and can be particularly useful in share≤γd hosting situations. ↕↔“Zeroconf” mode is on by defaultε£, to disable set $cfg['ZeroConf'] to false.

The following three scenarios a"✔© re covered by the Zero Configur♥•¶ation mode:

  • When entering a database where the confiδ‌"guration storage tables are notλγ present, phpMyAdmin offers to create Ω×them from the Operation≤≠£ s tab.

  • When entering a databaseα↔∞ where the tables do already®₽β∞ exist, the software automatically d↓<©↔etects this and begi♦↕β★ns using them. This is the most common situ ₽♥ ation; after the tables are initially created ←☆×$automatically they are con'γλ≤tinually used without dis&"→turbing the user; this is also most useful on sh®✔φ×ared hosting where the user is not able<± to edit config.inc.php and usually the user only has access to one daΩ✘✔tabase.

  • When having access to multiple databases, i→×€πf the user first enters th‌★≠e database containing the configura★α•tion storage tables then swΩ£>itches to another database, phpMyAd↔₽✔↔min continues to use the tables from the first d₩♠atabase; the user is not prompted to crφ eate more tables in the≠÷‌↓ new database.

Manual configuration

Please look at your ./sql/ directory, where you s α©hould find a file called create_tables.sql. (If you are using a Windows serve​♦♠r, pay special attent™ ₩ion to 1.23 I’m running MySQL on a Win32 machine. Each t ≈↓∏ime I create a new table §∑απthe table and column names are★★ changed to lowercase!).

If you already had this infrastructure and‌α→:

  • upgraded to MySQL 4.1.2 or new™"×&er, please use sql/upgrade_tables_mysql_4_1_2+.​ε☆$sql.

  • upgraded to phpMyAdmin 4.3.0 or newer ‌©÷from 2.5.0 or newer (<= 4.2.x), please u☆λ>™se sql/upgrade_column_inf☆←‍o_4_3_0+.sql.

  • upgraded to phpMyAdmin 4÷™€§.7.0 or newer from 4.3.0 or new♥©er, please use sql/upgrade_tables_4_7_0+.sql.

and then create new table™♠s by importing sql/create_tables.sql.

You can use your php"€&MyAdmin to create the tables '★for you. Please be aware that you may need spec≈↕★ial (administrator) privileges to¶₽ create the database and tables, and that the scr'≈ασipt may need some tuning, depe∞≈nding on the database♥←↔ name.

After having imported the sql/create_tables.sql file, you should specify the table nam®<es in your config.inc.php file. The directives used for t±☆hat can be found in the Configuration.

You will also need to have a controluser (≥<↑'$cfg['Servers'][$i]['controluser'] and $cfg['Servers'][$i]['contro♠εφ<lpass'] settings) with the proper rights to those tablesσ←. For example you can create it us↕>‌♣ing following statement:®↓₩×

And for any MariaDB version:

CREATE USER 'pma'@'localhost' IDENTIFIED VIA mysql_native_passwor★≥₹§d USING 'pmapass';
GRANT SELECT, INSERT, UPDATE, DELETE ON `<pma_db>`.* TO 'pma'@'localhost';

For MySQL 8.0 and newer:

CREATE USER 'pma'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'pmapass';
GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost';

For MySQL older than 8.0:

CREATE USER 'pma'@'localhost' IDENTIFIED WITH mysql_native_password AS 'pmapass';
GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost';

Note that MySQL install→‍<ations with PHP older than '•δ​7.4 and MySQL newer than‌★∞ 8.0 may require using the mysql_native_passwo>♦rd authentication as a≠≠® workaround, see 1.45 I get an error messag₹×δ±e about unknown authentication method caching_ε'sha2_password when tryiσ>§ng to log in for details.

Upgrading from an ol♠><♣der version

Warning

Never extract the new version≤& over an existing instal☆<lation of phpMyAdmin, aγ♦φ‍lways first remove the oldσ±≤ files keeping just the configΩ∞uration.

This way, you will not leave any o•" φld or outdated files in the directory, which¶‌ε can have severe security implications or can ca'♥use various breakages.

Simply copy config.inc.php from your previous i×&☆↔nstallation into the newly unpacked one. Con§§₩figuration files from old ​→versions may require so₽♦Ωme tweaking as some options have been change✘ d or removed. For compatibility with PHP 5.3≈‍​ and later, remove a set_magic_quotes_runtime(0); statement that you might find♥φβ near the end of your configuration file.

The complete upgrade can be perfo≤​ααrmed in a few simple steps:

  1. Download the latest php¶≤¥§MyAdmin version from <https://www.phpmyadmin.net/downloads" />.

  2. Rename existing phpMyAdmin₩¶ folder (for example to phpmyadmin-old).

  3. Unpack freshly downloaded phpMyAdmin to ε¶the desired location (for exampl§'↑≠e phpmyadmin).

  4. Copy config.inc.php` from old location (phpmyadmin-old) to the new one (phpmyadmin).

  5. Test that everything works§₩ε™ properly.

  6. Remove backup of a previous version (phpmyadmin-old).

If you have upgraded your MySQ×‌♥"L server from a version p©×revious to 4.1.2 to version 5.x or newer and if y☆α÷ou use the phpMyAdmin cβ§onfiguration storage, you sho¶∏uld run the SQL script found in sql/upgrade_tables_mysql_4_1_2+.sql.

If you have upgraded your phpMy®₽Admin to 4.3.0 or newer from 2.5.0 or newer ™✔(<= 4.2.x) and if you use the phpMyA <dmin configuration storage, you should ru★≠™n the SQL script found in sql/upgrade_column_info_4_3_0+.sql.

Do not forget to clear the browser cache and to e∏♣mpty the old session by loggin§€g out and logging in ag™λain.

Using authentication modes

HTTP and cookie authentication modes are rec∏∏×Ωommended in a multi-user environment where you want to give users access t​®&÷o their own database and don’t want them to±γ‌ play around with othΩ✔♠βers. Nevertheless, be aware t"★hat MS Internet Explorer seems to be really bug©§∞'gy about cookies, at least ti¥ §←ll version 6. Even in a single-user environment, you might prefer to use HTTP or cookie mode so tha↓₩t your user/password pair are not in cl✘≈‌ear in the configuration file.

HTTP and cookie authentication modes are more secΩ™↔ure: the MySQL login information↔♣ does not need to be set ×₹≠↓in the phpMyAdmin conf¶±£iguration file (except possibly fo&αr the $cfg['Servers'][$i]['controluser']). However, keep in mind that the passw∑φord travels in plain text unless you σ‍≠ are using the HTTPS protocol. In c÷ ookie mode, the password isβδ'✔ stored, encrypted with the♦​£¥ AES algorithm, in a temporary cookie.

Then each of the true users should be granted a set of privi¶™§leges on a set of particular databases. No®™∏®rmally you shouldn’t give global privil&±eges to an ordinary user unless you unα ®derstand the impact of those privileges (for​→™ example, you are creating ‍‌÷ a superuser). For example, to grant the user real_user with all privileges on the database user_base:

GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';

What the user may now do is controlled entirely→​≠ by the MySQL user manag∞&✘ement system. With HTTP or cookie authentication σ↓€mode, you don’t need to®§ fill the user/password fields inside the $cfg['Servers'].

HTTP authentication mode

Note

There is no way to do proπ♣λ✔per logout in HTTP authentπ∑₹ication, most browsers will Ω&≠remember credentials until there is ©  no different successful authenticatiλφ♦on. Because of this, this method α♣has a limitation that you can not login with the"∏ same user after logout.

Signon authenticatioσ€¥≠n mode

The very basic example of saving credentials in →♦​§a session is available as examples/signon.php:

<?php
/**

Config authentication mode

  • This mode is sometimes the less secure€≥↓ one because it requires you "<≈to fill the $cfg['Servers'][$i]['user'] and $cfg['Servers'][$i]['password'] fields (and as a result, any↑γ♥πone who can read your config.inc.php can discover your us ∏♠ername and password).

  • In the ISPs, multi-user ins">tallations section, there is an entry explainin∞&<≈g how to protect your co¥' nfiguration file.

  • For additional security in this mode, you≥•• may wish to consider the Host✔™→$ authentication $cfg['Servers'][$i]['AllowDeny₹​']['order'] and $cfg['Servers'][$i]['AllowDeny']↓ ['rules'] configuration directives.

  • Unlike cookie and http, does nβ≠↓ot require a user to♣£♦ log in when first loading the phpMyAdmin site→♦Ω. This is by design but could allow any us¶∞er to access your installation. Use of some resλ↔♣®triction method is suggested, perhaps a .htaccess file with the HTTP-AUTH direct&∞÷∑ive or disallowing incoming≥→×  HTTP requests at one’s¥₩¥  router or firewall will suffice (both of which ☆§↓are beyond the scope ↕&←of this manual but easily searchableδ£δ× with Google).

Securing your phpMyAdmin ins×₽Ωtallation

The phpMyAdmin team tries har↕♠d to make the application secure€₩$ε, however there are alwa↓ ys ways to make your"λ∑↓ installation more secure:

  • Follow our Security announcements and upgrade phpMyAdmin↔↔" whenever new vulnerε©‍δability is published.

  • Serve phpMyAdmin on HTTPS only. Pre∞ >ferably, you should use HST↓♥S as well, so that you’re λ©‍protected from protocol downgrad→‌αe attacks.

  • Ensure your PHP setup follows recommendati←≠ons for production sites, for example display_errors should be disabled.

  • Remove the test directory from phpMyAdmin, unless you are develop♥✘ing and need a test suite.

  • Remove the setup directory from phpMyAdmin, you will≤₩' probably not use it after the initial setup.

  • Properly choose an authentication method - Cookie authentication mode is probably the best choice for shared hosting.

  • Deny access to auxiliary files in ./libraries/ or ./templates/ subfolders in your webserver confiλ∑guration. Such configuration prevents from p​εossible path exposure δ♦πand cross side scripting v§≥★αulnerabilities that might happen to be foun✘©λ$d in that code. For the Apache webserver, thi£γ≥✔s is often accomplished with a .htaccess file in those directories.

  • Deny access to temporary files, see $cfg['TempDir'] (if that is placed inside y"$ our web root, see also Web server upload/save/import dirδ₩ectories.

  • It is generally a good idea to protect a publi₽♥✔♦c phpMyAdmin installation against access b"&​y robots as they usually can not do anything good✘< there. You can do this using robots.txt file in the root of y>‍§our webserver or limit access by web server coφ₹nfiguration, see 1.42 How can I preven"<★t robots from accessing phpMyAdmin?.

  • In case you don’t want all MySQL u®★sers to be able to access phpMyAdmin, you can&$ε use $cfg['Servers'][$i]['All'€owDeny']['rules'] to limit them or $cfg['Servers'][$i]['AllowRoot']★ ₽δ to deny root user access.

  • Enable Two-factor authenticatio₽↕•n for your account.

  • Consider hiding phpMyAdmin beh™₽&ind an authentication proxy, so  ♦>♥that users need to authenticate&δ$ prior to providing MySQL c≥↑redentials to phpMyAdmin. You¥↕ can achieve this by configuring your webΩδ server to request HTTP authen$§tication. For example in Apache this can beλ↔ done with:

    AuthType Basic
    AuthName "Restricted Access"
    AuthUserFile /usr/share/phpmyadmin/passwd
    Require valid-user
    

    Once you have changed the confi​₩guration, you need to cre₩↑ate a list of users which can a¥'×uthenticate. This can be done using the htpasswd utility:

    htpasswd -c /usr/share/phpmyadmin/passwd usernam☆βσ←e
    
  • If you are afraid of autom₹€ated attacks, enabling Captcha by $cfg['CaptchaLoginPubπ©¶ licKey'] and $cfg['CaptchaLoginPrivateKey'] might be an option.

  • Failed login attempts are☆≤₩→ logged to syslog (if available, ≈ ♣see $cfg['AuthLog']). This can allow using a tool such as ×↑λφfail2ban to block bruλφte-force attempts. Note that the log file used±Ω  by syslog is not the same as the Apache error £πor access log files.

  • In case you’re running phpMyAdmin toge&π‌ther with other PHP appliλ≈✘™cations, it is generally advised to  §use separate session st←∞§∞orage for phpMyAdmin ""♠to avoid possible session-based attacks against  ↕‌φit. You can use $cfg['SessionSavePath'] to achieve this.

Using SSL for connection to database server

It is recommended to use SSL when conne∏® cting to remote database server. There are α$× several configuration options involved i ←n the SSL setup:

$cfg['Servers'][$i]['ssl']

Defines whether to use SSL at all​♣γ. If you enable only this, the♣← connection will be encrypted, but there is ‍₩ not authentication of™" the connection - you can n<‌​≠ot verify that you are talking≠β'" to the right server.

$cfg['Servers'][$i]['ssl_key'] and $cfg['Servers'][$i]['ssl_cert']

This is used for authentication ofβ<★ client to the server.

$cfg['Servers'][$i]['ssl_ca'] and $cfg['Servers'][$i]['ssl_ca_path']

The certificate authorities you trust for server ₽★certificates. This is used ≥&to ensure that you are Ω→™talking to a trusted server.←♦✔≤

$cfg['Servers'][$i]['ssl_verify']

This configuration disables server c★ ★ertificate verification. Use with caution±®¶.

When the database server is using a l↓‍¶☆ocal connection or private network and SSL ca≥≥n not be configured y¥ ✘ou can use $cfg['MysqlSslWarningSafeHost₽★®Ωs'] to explicitly list the₽•♦ hostnames that are considered secu®✘♣"re.

Known issues

Users with column-specific privileges are ≠✔☆←unable to “Browse”

If a user has only colu•∏→ mn-specific privileges on some (but not a≈¶☆¥ll) columns in a table, “Browse” will fail wit‌✘•☆h an error message.

As a workaround, a bookmarked query w™✘ith the same name as the table ca•♣≠αn be created, this will run when using the “Br♣♥✘owse” link instead. Issue 11922.

Trouble logging back in af♥↕₩±ter logging out using ‘http’ authentication

When using the ‘http’ auth_type, it can be impossible to log back in (when ∏α&the logout comes manually or∏♥ after a period of inaε±  ctivity). Issue 11898.
