Line 1: Line 1:
-===== Configuration ===== +====== phpMyAdmin ====== 
-  - We will not use any of the standard path used in Debian versions up to 9 or in other distributions. All files related to phpMyAdmin will remain in the custom path where we moved the downloaded files which is the easiest way for maintenance and later version upgrades (''/home/user/html/phpMyAdmin''). +===== Remove repository-installation ===== 
-  - Make a new directory for phpMyAdmin to store its temporary files:<code>$ sudo mkdir -m770 /home/user/html/phpMyAdmin/tmp</code> +  - **Purge the Package and dependencies if you previously installed it from Debian's repository**: The purge flag instructs ''apt'' to erase the package binaries along with its main configuration files.<code>sudo apt purge phpmyadmin 
-  - Copy ''config.sample.inc.php'' to ''config.inc.php'' and edit as follows +sudo apt autoremove --purge</code> 
-    - Use the [[https://phpsolved.com/phpmyadmin-blowfish-secret-generator/?g=6330fef62b5a1|phpMyAdmin blowfish secret generator]] to create a new secret passphrase for cookie authentication:<code>$ sudo vim /home/user/html/phpMyAdmin/config.inc.php +  - **Delete remaining configuration & web root leftovers**: ''apt'' sometimes leaves empty directories or user-modified configuration blocks untouched. Wipe them completely with the following commands:<code>sudo rm -rf /etc/phpmyadmin 
-$cfg['blowfish_secret'] = 'new 32 byte secret key';</code> +sudo rm -rf /usr/share/phpmyadmin 
-    - Add the following custom settings to ''config.inc.php'':<code>$cfg['FirstLevelNavigationItems'] = 150; // number of databases in navigation, default: 100+sudo rm -rf /var/lib/phpmyadmin</code> 
 +  - **Clear web server configurations**: remove apache's setup link and reload the service:<code>sudo rm -f /etc/apache2/conf-available/phpmyadmin.conf 
 +sudo rm -f /etc/apache2/conf-enabled/phpmyadmin.conf 
 +sudo systemctl reload apache2</code> 
 +  - **Remove the phpMyAdmin storage database**: If dbconfig-common didn't automatically drop the internal tracking database, log into your MySQL/MariaDB terminal to remove it:<code>sudo mysql -u root -p 
 +DROP DATABASE IF EXISTS phpmyadmin; 
 +DROP USER IF EXISTS 'phpmyadmin'@'localhost'; 
 +FLUSH PRIVILEGES; 
 +# check databases and users 
 +SHOW DATABASES; 
 +SELECT User, Host FROM mysql.user; 
 +EXIT; 
 +</code> 
 + 
 +===== Installation ===== 
 +  - We will not use any of the standard paths used in Debian or other distributions. All files related to phpMyAdmin will remain in the custom path (e.g. ''/home/user/html/phpMyAdmin'') where we download the files and which is the easiest way for maintenance and later version upgrades.\\ \\ 
 +  - Navigate to ''/home/user/html'', download the latest stable tarball, extract it, and rename the folder:<code>cd /home/user/html 
 +sudo wget https://www.phpmyadmin.net/downloads/phpMyAdmin-latest-english.tar.gz 
 +sudo tar -xvzf phpMyAdmin-latest-english.tar.gz 
 +sudo rm phpMyAdmin-latest-english.tar.gz 
 +sudo mv phpMyAdmin-*-english phpmyadmin 
 +</code> 
 +  - Create the temporary folder required by phpMyAdmin and assign proper web server ownership:<code>$ sudo mkdir -p /home/user/html/phpMyAdmin/tmp 
 +$ sudo chown -R www-data:www-data /home/user/html/phpMyAdmin 
 +$ sudo chmod -R o-rwx /home/user/html/phpMyAdmin</code> 
 +  - To upgrade to a newer version simply download the new version and extract it to the same folder. Files created by the user will remain the same, e.g. ''apache.conf'', ''config.inc.php'', and ''htpasswd.setup''. 
 +  * __Note__: Debian 10 dropped //phpmyadmin// from it's repository. Older and newer Debian versions include it. 
 + 
 +===== phpMyAdmin Configuration ===== 
 +  - Create the configuration file from the sample template and generate a secure blowfish secret for cookie encryption:<code>sudo cp /home/user/html/phpmyadmin/config.sample.inc.php /usr/share/phpmyadmin/config.inc.php</code> 
 +  - Generate a 32-character random string using OpenSSL:<code>openssl rand -base64 24 > secret</code> 
 +  - Open ''/home/user/html/phpmyadmin/config.inc.php'' and paste the generated string into the $cfg['blowfish_secret'] line:<code>$cfg['blowfish_secret'] = 'YOUR_GENERATED_STRING_HERE';</code> 
 +  - Add custom settings:<code>$cfg['FirstLevelNavigationItems'] = 150; // number of databases in navigation, default: 100
 $cfg['MaxNavigationItems'] = 150; // number of tables in db navigation, default: 50 $cfg['MaxNavigationItems'] = 150; // number of tables in db navigation, default: 50
 $cfg['NavigationWidth'] = 300; // width of the navigation window, default: 240 $cfg['NavigationWidth'] = 300; // width of the navigation window, default: 240
Line 11: Line 43:
 $cfg['ShowPhpInfo'] = true; // show phpinfo link on home screen, default: false $cfg['ShowPhpInfo'] = true; // show phpinfo link on home screen, default: false
 $cfg['TempDir'] = '/home/user/html/phpMyAdmin/tmp'; // you may omit this line as the default is ./tmp</code> $cfg['TempDir'] = '/home/user/html/phpMyAdmin/tmp'; // you may omit this line as the default is ./tmp</code>

-    - Leave the commented out settings in ''config.inc.php'' unchanged. The ''pma'' settings are better done within phpMyAdmin, where you click "Find out why" in the warning at the bottom of the screen when you first run phpMyAdmin, and then create the database ''phpmyadmin'' which will contain those settings. +  - Leave the commented out settings in ''config.inc.php'' unchanged.

-  - You can replace the directives for the setup directory with ''Require all denied'' as we will not use the setup script. However, if you do want to use the setup script prior to creating ''config.inc.php'', first create the password file to access the setup script's directory:<code>$ sudo htpasswd -c /home/user/html/phpMyAdmin/htpasswd.setup user</code> +  - Enable the configuration, check the configuration, and restart apache:<code>$ sudo a2enconf phpmyadmin 
-  - Symlink the configuration file for Apache and restart the service:<code>$ sudo ln -s /home/user/html/phpMyAdmin/apache.conf /etc/apache2/conf-enabled/phpmyadmin.conf +$ sudo apachectl configtest 
-$ sudo service apache2 restart</code> +$ sudo systemctl restart apache2</code> 
-  - Create a regular MariaDB user for the purpose of managing databases through phpMyAdmin, if you haven't done that yet when configuring MariaDB. You could create a user that has privileges to all tables within the database, as well as the power to add, change, and remove user privileges, with this command. Whatever privileges you assign to this user, be sure to give it a strong password as well:<code>$ sudo mariadb+  - Create a regular MariaDB user for the purpose of managing databases through phpMyAdmin, if you haven't done that yet when configuring MariaDB.
