How To Repair Phpmyadmin In Ubuntu

phpMyAdmin is a popular open-source tool for managing MySQL and MariaDB databases through a web-based interface. It offers a convenient way to perform operations like creating, modifying, and deleting databases, tables, and records. However, sometimes issues can arise in phpMyAdmin that may require you to repair it. In this blog post, we will discuss how to repair phpMyAdmin in Ubuntu.

Step 1: Diagnose the Problem

Before attempting any repairs, it’s essential to diagnose the problem. Common issues with phpMyAdmin include:

  • 404 Not Found error when trying to access phpMyAdmin
  • Permission issues
  • Database connection errors
  • Missing or corrupted files

Check your web server’s error logs for any clues to the issue. In most cases, the error logs can be found in the following location:


Step 2: Reinstall or Update phpMyAdmin

If you suspect that the issue is related to missing or corrupted files, you can try reinstalling or updating phpMyAdmin. To do this, first, remove the existing installation:

    sudo apt-get remove --purge phpmyadmin

Now, update your package list and install phpMyAdmin:

    sudo apt-get update
    sudo apt-get install phpmyadmin

During the installation process, you will be prompted to select a web server. Make sure to select the correct web server (Apache or Nginx) that you are using. After the installation is complete, restart your web server:

    sudo service apache2 restart

Step 3: Fix Permission Issues

If you are experiencing permission issues with phpMyAdmin, you can use the following command to set the correct permissions:

    sudo chown -R www-data:www-data /usr/share/phpmyadmin

Step 4: Configure Database Connection

Ensure your database connection settings are correct in the phpMyAdmin configuration file. Open the configuration file with a text editor:

    sudo nano /etc/phpmyadmin/

Locate the following lines and ensure they match your database settings:

    $cfg['Servers'][$i]['host'] = 'localhost';
    $cfg['Servers'][$i]['user'] = 'root';
    $cfg['Servers'][$i]['password'] = 'your_password';
    $cfg['Servers'][$i]['extension'] = 'mysqli';

Replace ‘your_password’ with your actual root password for MySQL/MariaDB. Save the changes and exit the text editor.

Step 5: Restart Services

After making any changes to configuration files, restart your web server and the MySQL/MariaDB service:

    sudo service apache2 restart
    sudo service mysql restart

Now, access your phpMyAdmin installation at http://your_server_ip/phpmyadmin or http://localhost/phpmyadmin and verify that the issues have been resolved. If not, consider checking the error logs and troubleshooting further.
