How To Uninstall Nextcloud on Linux Installed via Web Installer

Ubuntu 12

In this article, we’ll walk you through the process of uninstalling Nextcloud from a Linux server when it was installed using the web installer. The process involves disabling the Apache configuration, removing Nextcloud files, clearing out the Nextcloud database, and removing any firewall rules related to Nextcloud.

Quick Answer

To uninstall Nextcloud on Linux installed via the web installer, you need to disable the Apache configuration, remove Nextcloud files, clear out the Nextcloud database, and remove any firewall rules related to Nextcloud.

Prerequisites

Before you proceed, ensure that you have SSH access to your server and you are comfortable executing commands in the terminal. It’s also advisable to have a backup of your data before you begin.

Disabling the Apache Configuration

The first step in the uninstallation process is to disable the Apache configuration for Nextcloud.

  1. SSH into your server.
  2. Navigate to Apache’s sites-available directory:
    cd /etc/apache2/sites-available
    This is where Apache stores configuration files for your websites.
  3. Identify the Apache configuration file used by Nextcloud:
    grep -rnw '/etc/apache2/sites-available' -e 'nextcloud'
    This command searches for the term ‘nextcloud’ within the directory /etc/apache2/sites-available.
  4. Disable the Nextcloud site:
    sudo a2dissite <NextCloud_configuration_file>
    Replace <NextCloud_configuration_file> with the actual file name. The a2dissite command disables the specified site within the Apache server.
  5. Reload or restart Apache:
    sudo service apache2 reload
    This command ensures that the changes are applied by restarting the Apache service.

Removing Nextcloud Files

After disabling the Apache configuration, the next step is to remove the Nextcloud files from the server.

  1. Navigate to the Apache root directory:
    cd /var/www
  2. Backup Nextcloud (optional):
    sudo tar -czvf nextcloud-backup.tar.gz nextcloud
    This command creates a compressed backup of your Nextcloud files. It’s a good practice to have a backup before making any significant changes.
  3. Remove Nextcloud:
    sudo rm -Rf /var/www/nextcloud
    This command removes the Nextcloud directory and all its contents.

Clearing Out the Nextcloud Database

Next, you need to clear out the Nextcloud database.

  1. Connect to MySQL via the command line as the administrator:
    sudo mysql
  2. List all databases to confirm the Nextcloud database name:
    SHOW DATABASES;
    This command lists all the databases present in your MySQL server.
  3. Remove the Nextcloud database:
    DROP DATABASE <NextCloud_database_name>;
    Replace <NextCloud_database_name> with the actual database name. This command deletes the specified database.
  4. Exit MySQL:
    quit;

Removing Nextcloud Firewall Rules

If you have set up any firewall rules for Nextcloud, you need to remove them as well. You can use a firewall management tool like UFW (Uncomplicated Firewall) to locate and delete Nextcloud rules.

Conclusion

Uninstalling Nextcloud from a Linux server involves several steps, including disabling the Apache configuration, removing Nextcloud files, clearing out the Nextcloud database, and removing any firewall rules. Always remember to backup your data before proceeding with the uninstallation process. If you encounter any issues, refer to the official Nextcloud documentation or seek help from the community forums.

Remember, these steps are based on a typical server setup and might vary depending on your specific configuration. Always adjust the commands and paths according to your setup.
