Sentora is a popular open-source web hosting control panel that allows users to manage multiple websites, emails, and databases. While it offers a plethora of features, there might be instances where you’d want to uninstall it, perhaps to switch to another control panel or to troubleshoot specific issues.
This guide will walk you through the steps to completely uninstall Sentora from your Ubuntu server. Before proceeding, it’s essential to back up any critical data, as this process will remove all associated files and configurations.
Let’s get started.
Step 1: Backup Your Data
Before making any changes to your server, it’s crucial to back up all essential data. This includes website files, databases, emails, and any other critical information. Use tools like rsync or tar to create backups of your directories.
1.1: Using rsync for File Backup
rsync is a powerful tool that allows for fast incremental file transfer. Here’s how you can use it:
rsync -avz /path/to/source_directory/ /path/to/backup_directory/
-a stands for “archive” and syncs directories recursively, preserving symbolic links, file permissions, and timestamps.
-v increases verbosity, allowing you to see the files being transferred.
-z compresses the data, speeding up the transfer.
1.2: Using tar for Archiving
tar is a utility that creates archive files. To create a compressed archive of your directory:
tar -czvf backup_name.tar.gz /path/to/source_directory/
-c creates a new archive.
-z compresses the archive using gzip.
-v displays the progress in the terminal.
-f allows you to specify the filename of the archive.
1.3: Backup Databases
For MySQL databases, use the mysqldump command:
mysqldump -u [username] -p[password] [database_name] > backup_name.sql
Replace [username], [password], and [database_name] with your MySQL credentials and the name of the database you want to back up.
1.4: Store Backups Safely
Once you’ve created your backups, store them in a safe location. Consider using external storage devices, cloud storage solutions, or even a different server. Regularly test your backups to ensure they’re intact and can be restored when needed.
Step 2: Stop All Sentora Services
To ensure a smooth uninstallation process, first stop all services related to Sentora:
sudo service apache2 stop sudo service proftpd stop sudo service postfix stop sudo service dovecot stop sudo service mysql stop
Step 3: Remove Sentora Packages
Now, uninstall the Sentora core and all related packages:
sudo apt-get purge sentora-core sudo apt-get autoremove
Step 4: Remove Sentora Directories
After uninstalling the packages, remove all directories associated with Sentora:
sudo rm -rf /etc/sentora sudo rm -rf /var/sentora
Step 5: Drop Sentora Databases
Before proceeding, log into your MySQL server:
mysql -u root -p
Once inside, drop all Sentora related databases:
DROP DATABASE sentora_core; DROP DATABASE sentora_postfix; DROP DATABASE sentora_proftpd; DROP DATABASE sentora_roundcube;
Exit the MySQL prompt:
- sudo service [service-name] stop – Stops the specified service.
- sudo apt-get purge [package-name] – Completely removes the specified package and its configuration files.
- sudo rm -rf [directory-path] – Recursively removes the specified directory and its contents.
- mysql -u root -p – Logs into the MySQL server as the root user.
- DROP DATABASE [database-name]; – Deletes the specified database from MySQL.
