phpMyAdmin is a web-based tool to help manage MariaDB or MySQL databases, written primarily in PHP and distributed under the GNU GPL.

## Installation

Install the phpmyadmin package.

## Running

### PHP

Make sure the PHP mariadb and `iconv` extensions have been enabled.

Optionally you can enable `extension=bz2` and `extension=zip` for compression support.

Note: If `open_basedir` has been set, make sure to include `/usr/share/webapps` and `/etc/webapps` to `open_basedir` in `/etc/php/php.ini`. See PHP#Configuration.

### Apache

Set up Apache to use PHP as outlined in the Apache HTTP Server#PHP article.

Create the Apache configuration file:

    /etc/httpd/conf/extra/phpmyadmin.conf

    Alias /phpmyadmin "/usr/share/webapps/phpMyAdmin"
    <Directory "/usr/share/webapps/phpMyAdmin">
        DirectoryIndex index.php
        AllowOverride All
        Options FollowSymlinks
        Require all granted
    </Directory>

And include it in `/etc/httpd/conf/httpd.conf`:

    # phpMyAdmin configuration
    Include conf/extra/phpmyadmin.conf

Note: By default, everyone who can reach the Apache Web Server can see the phpMyAdmin login page under this URL. To change this, edit `/etc/httpd/conf/extra/phpmyadmin.conf` to your liking. For example, if you only want to be able to access it from the same machine, replace `Require all granted` by `Require local`. Beware that this will disallow connecting to PhpMyAdmin on a remote server. If you still want to access PhpMyAdmin on a remote server securely, you might want to consider setting up an OpenSSH#Encrypted SOCKS tunnel.

After making changes to the Apache configuration file, restart `httpd.service`.

### Lighttpd

Configuring Lighttpd, make sure it is able to serve PHP files and `mod_alias` has been enabled.

Add the following alias for PhpMyAdmin to the config:

    alias.url = ( "/phpmyadmin" => "/usr/share/webapps/phpMyAdmin/")

### Nginx

Make sure to set up nginx#FastCGI and use nginx#Server blocks to make management easier.

By preference, access phpMyAdmin by subdomain, e.g. `https://pma.domain.tld`:

    /etc/nginx/sites-available/pma.domain.tld

    server {
        server_name pma.domain.tld;
        ; listen 80; # also listen on http
        ; listen [::]:80;
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        index index.php;
        access_log /var/log/nginx/pma.access.log;
        error_log /var/log/nginx/pma.error.log;

        # Allows limiting access to certain client addresses.
        ; allow 192.168.1.0/24;
        ; allow my-ip;
        ; deny all;

        root /usr/share/webapps/phpMyAdmin;
        location / {
            try_files $uri $uri/ =404;
        }

        error_page 404 /index.php;

        location ~ \.php$ {
            try_files $uri $document_root$fastcgi_script_name =404;

            fastcgi_split_path_info ^(.+\.php)(/.*)$;
            fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;

            fastcgi_param HTTP_PROXY "";
            fastcgi_param HTTPS on;
            fastcgi_request_buffering off;
       }
    }

Or by subdirectory, e.g. `https://domain.tld/phpMyAdmin`:

    /etc/nginx/sites-available/domain.tld

    server {
        server_name domain.tld;
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        index index.php;
        access_log /var/log/nginx/domain.tld.access.log;
        error_log /var/log/nginx/domain.tld.error.log;

        root /srv/http/domain.tld;
        location / {
            try_files $uri $uri/ =404;
        }

        location /phpMyAdmin {
            root /usr/share/webapps/phpMyAdmin;
        }

        # Deny static files
        location ~ ^/phpMyAdmin/(README|LICENSE|ChangeLog|DCO)$ {
           deny all;
        }

        # Deny .md files
        location ~ ^/phpMyAdmin/(.+\.md)$ {
          deny all;
       }

       # Deny setup directories
       location ~ ^/phpMyAdmin/(doc|sql|setup)/ {
          deny all;
       }

       #FastCGI config for phpMyAdmin
       location ~ /phpMyAdmin/(.+\.php)$ {
          try_files $uri $document_root$fastcgi_script_name =404;

          fastcgi_split_path_info ^(.+\.php)(/.*)$;
          fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
          fastcgi_index index.php;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          include fastcgi_params;

          fastcgi_param HTTP_PROXY "";
          fastcgi_param HTTPS on;
          fastcgi_request_buffering off;
       }
    }

## Configuration

The main configuration file is located at `/usr/share/webapps/phpMyAdmin/config.inc.php`.

### Define a remote MySQL server

If the MySQL server is a remote host, append the following line to the configuration file:

    $cfg['Servers'][$i]['host'] = 'example.com';

### Using setup script

To allow the usage of the phpMyAdmin setup script (e.g. http://localhost/phpmyadmin/setup), make sure `/usr/share/webapps/phpMyAdmin` is writable for the `http` user:

    # mkdir /usr/share/webapps/phpMyAdmin/config
    # chown http:http /usr/share/webapps/phpMyAdmin/config
    # chmod 750 /usr/share/webapps/phpMyAdmin/config

### Add blowfish_secret passphrase

It is required to enter a unique 32 characters long string to fully use the blowfish algorithm used by phpMyAdmin, thus preventing the message ERROR: The configuration file now needs a secret passphrase (blowfish_secret):

    /usr/share/webapps/phpMyAdmin/config.inc.php

    $cfg['blowfish_secret'] = '...';

### Enabling Configuration Storage

Extra options such as table linking, change tracking, PDF creation, and bookmarking queries are disabled by default, displaying The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. on the homepage.

Note: This example assumes you want to use the default username pma as the `controluser`, and pmapass as the `controlpass`.

In `/usr/share/webapps/phpMyAdmin/config.inc.php`, uncomment (remove the leading "//"s), and change them to your desired credentials if needed:

    /usr/share/webapps/phpMyAdmin/config.inc.php

    /* User used to manipulate with storage */
    // $cfg['Servers'][$i]['controlhost'] = 'my-host';
    // $cfg['Servers'][$i]['controlport'] = '3306';
    $cfg['Servers'][$i]['controluser'] = 'pma';
    $cfg['Servers'][$i]['controlpass'] = 'pmapass';

    /* Storage database and tables */
    $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
    $cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark';
    $cfg['Servers'][$i]['relation'] = 'pma__relation';
    $cfg['Servers'][$i]['table_info'] = 'pma__table_info';
    $cfg['Servers'][$i]['table_coords'] = 'pma__table_coords';
    $cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages';
    $cfg['Servers'][$i]['column_info'] = 'pma__column_info';
    $cfg['Servers'][$i]['history'] = 'pma__history';
    $cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs';
    $cfg['Servers'][$i]['tracking'] = 'pma__tracking';
    $cfg['Servers'][$i]['userconfig'] = 'pma__userconfig';
    $cfg['Servers'][$i]['recent'] = 'pma__recent';
    $cfg['Servers'][$i]['favorite'] = 'pma__favorite';
    $cfg['Servers'][$i]['users'] = 'pma__users';
    $cfg['Servers'][$i]['usergroups'] = 'pma__usergroups';
    $cfg['Servers'][$i]['navigationhiding'] = 'pma__navigationhiding';
    $cfg['Servers'][$i]['savedsearches'] = 'pma__savedsearches';
    $cfg['Servers'][$i]['central_columns'] = 'pma__central_columns';
    $cfg['Servers'][$i]['designer_settings'] = 'pma__designer_settings';
    $cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';

#### Setup database

Two options are available to create the required tables:

- Import `/usr/share/webapps/phpMyAdmin/sql/create_tables.sql` by using PhpMyAdmin.
- Execute `mysql -u root -p < /usr/share/webapps/phpMyAdmin/sql/create_tables.sql` in the command line.

#### Setup database user

To apply the required permissions for `controluser`, execute the following query:

Note: Make sure to replace all instances of `pma` and `pmapass` to the values set in `config.inc.php`. If you are setting this up for a remote database, then you must also change `localhost` to the proper host.

    GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
    GRANT SELECT (
        Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
        Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
        File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
        Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
        Execute_priv, Repl_slave_priv, Repl_client_priv
        ) ON mysql.user TO 'pma'@'localhost';
    GRANT SELECT ON mysql.db TO 'pma'@'localhost';
    GRANT SELECT ON mysql.host TO 'pma'@'localhost';
    GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
        ON mysql.tables_priv TO 'pma'@'localhost';

In order use the bookmark and relation features, set the following permissions:

    GRANT SELECT, INSERT, UPDATE, DELETE ON phpmyadmin.* TO 'pma'@'localhost';

Re-login to ensure the new features are activated.

### Enabling template caching

Edit `/usr/share/webapps/phpMyAdmin/config.inc.php` to add the line:

    $cfg['TempDir'] = '/tmp/phpmyadmin';

### Remove config directory

Remove temporary configuration directory once configuration is done. This will also suppress warning from web interface:

    # rm -r /usr/share/webapps/phpMyAdmin/config

### Install themes

Themes are located in `/usr/share/webapps/phpMyAdmin/themes`. You can find new themes in https://www.phpmyadmin.net/themes/

You can simply download and extract the new theme and it will work after phpmyadmin refresh. However, you have to download theme for the correct version of phpmyadmin, themes for older versions will not work.
