How to Uninstall ISPConfig on Ubuntu

ISPConfig is a widely used open-source hosting control panel for Linux, allowing webmasters and administrators to manage multiple servers, websites, customers, and more. While ISPConfig is feature-rich and offers a lot of functionalities, there might be instances where you need to uninstall it, perhaps to switch to another control panel or to perform a fresh installation.

In this guide, we will walk you through the steps to uninstall ISPConfig on an Ubuntu system.

Let’s get started.

Step 1: Backup Your Data

Before making any significant changes to your server, especially uninstalling a control panel like ISPConfig, it’s paramount to ensure all your essential data is safely backed up. This will allow you to restore your data in case anything goes wrong or if you decide to reinstall ISPConfig in the future. Here’s a detailed breakdown of the backup process:

1.1 Backup Website Files

Your website files include all the HTML, CSS, JavaScript, images, and other assets that make up your website. To back up these files:

cd /var/www/
sudo tar -czvf website_backup.tar.gz html/

This command navigates to the /var/www/ directory, where your website files are typically stored, and creates a compressed backup named website_backup.tar.gz.

1.2 Backup Databases

If you’re using MySQL or MariaDB, you can use the mysqldump command:

sudo mysqldump -u [username] -p[password] [database_name] > database_backup.sql

Replace [username], [password], and [database_name] with your database credentials. This command will create a backup of your database in the form of an SQL file.

1.3 Backup Email Configurations

If you’re using ISPConfig for email hosting, you’ll want to back up your email configurations and data:

cd /var/vmail/
sudo tar -czvf email_backup.tar.gz [domain_name]/

Replace [domain_name] with your email domain. This command will back up all email data associated with the specified domain.

1.4 Backup Custom Configuration Files

If you’ve made custom configurations to services like Apache, Nginx, or PHP, ensure you back up their configuration files. For instance, to backup Apache configurations:

cd /etc/apache2/
sudo tar -czvf apache_config_backup.tar.gz sites-available/ sites-enabled/

1.5 Store Backups Safely

Once you’ve created your backups, it’s essential to store them in a safe location. Consider copying them to an external storage device or a cloud storage service. For example, to copy the website backup to an external directory:

sudo cp website_backup.tar.gz /path/to/external/storage/

Replace /path/to/external/storage/ with the path to your backup storage location.

Step 2: Stop ISPConfig and Related Services

First, you need to stop the ISPConfig service and any related services to ensure a smooth uninstallation process.

sudo service ispconfig stop
sudo service apache2 stop
sudo service mysql stop

Step 3: Remove ISPConfig Directories

Once the services are stopped, you can proceed to remove the ISPConfig directories.

sudo rm -rf /usr/local/ispconfig
sudo rm -rf /var/www/ispconfig

Step 4: Remove ISPConfig Database

ISPConfig uses a database to store its configurations. You need to remove this database.

sudo mysql -u root -p
DROP DATABASE dbispconfig;
EXIT;

Step 5: Remove ISPConfig User and Group

ISPConfig creates a specific user and group for its operations. These should be removed as well.

sudo userdel ispconfig
sudo groupdel ispconfig

Step 6: Clean Up Configuration Files

There might be some residual configuration files left on the system. It’s a good practice to remove them.

sudo rm /etc/apache2/sites-available/ispconfig.conf
sudo rm /etc/cron.d/ispconfig
