How to Install phpMyAdmin in Debian 11

In this guide, we will demonstrate how phpMyAdmin is installed on a Debian 11 system. phpMyAdmin requires a standalone Database or as part of the LAMP stack, installed and running on the system before hand.

Prerequisites

Server with Apache, PHP, and MariaDB installed and running.

You can refer to the article we have for setting up LAMP Stack in case you do not have the required services running.

Updating the system

We first update the system to make sure that all our installed packages are up to date. Your Ubuntu system can be updated easily with the following command.

apt update

apt upgrade

Install the required phpMyAdmin packages.

apt install php-mbstring php-zip php-gd

Downloading phpMyAdmin

phpMyAdmin isn’t included in Debian 11 software repository, so you'll need to manually download the software. Navigate to phpMyAdmin download page to check the latest stable version. Then run the following command to download it.

wget https://files.phpmyadmin.net/phpMyAdmin/5.1.1/phpMyAdmin-5.1.1-all-languages.tar.gz

Extract the downloaded file.

tar xvf phpMyAdmin-5.1.1-all-languages.tar.gz

Move the phpMyAdmin-5.1.1-all-languages to /usr/share/ directory.

mv phpMyAdmin-5.1.1-all-languages /usr/share/phpmyadmin

Configuring phpMyAdmin

Create a sub-directroy with the following command.

mkdir -p /var/lib/phpmyadmin/tmp

Make the web server user www-data as the owner of this directory.

chown -R www-data:www-data /var/lib/phpmyadmin

Make a copy to the file /usr/share/phpmyadmin/config.inc.php

cp /usr/share/phpmyadmin/usr/share/phpMyAdmin-5.1.1-all-languages/config.inc.php

Edit the /usr/share/phpmyadmin/config.inc.php file as follows using preferred text editor.

nano /usr/share/phpmyadmin/config.inc.php

Enter a string of 32 random characters in between single quotes.

$cfg['blowfish_secret'] = 'STRINGOFTHIRTYTWORANDOMCHARACTERS'; 
/* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

Note: Do not re-use "STRINGOFTHIRTYTWORANDOMCHARACTERS", generate a random 32 character string and use.

Install and use the pwgen program.

apt install pwgen

Generate Random a Password.

pwgen -s 32 1

Then uncomment this section of the /usr/share/phpmyadmin/config.inc.php file will look like as follows:

 /* 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';

Add the following line to bottom of the file.

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

Then save & exit the file.

Create a MariaDB Database and User for phpMyAdmin

Create the configuration storage database and tables by running the following command.

mariadb < /usr/share/phpmyadmin/sql/create_tables.sql

Open the MariaDB prompt.

mariadb

Create the pma user and grant it the appropriate permissions and Replace texts with your preferred password.

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

GRANT ALL PRIVILEGES ON *.* TO 'john'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;

exit;

Output:

root@server:~# mariadb

Bye

Create Apache Configuration for phpMyAdmin

Create a configuration file with the following command.

nano /etc/apache2/conf-available/phpmyadmin.conf

Paste the following text into the file.

 # phpMyAdmin default Apache configuration

Alias /phpmyadmin /usr/share/phpmyadmin
