1. Disable the IDO MySQL Feature
First, it’s a good practice to disable the feature before deleting any configuration files associated with it. You can disable the IDO MySQL feature by running:
sudo icinga2 feature disable ido-mysql
sudo systemctl stop icinga2
sudo rm /etc/icinga2/features-available/ido-mysql.conf
sudo apt-get purge icinga2-ido-mysql # This removes the package and its configuration files
sudo apt-get purge icinga2-ido-mysql
sudo apt-get clean
sudo apt-get autoremove
This command disables the IDO MySQL module, stopping Icinga2 from attempting to use it for database output.
2. Restart Icinga2
After disabling the feature, you should restart Icinga2 to apply the changes:
sudo systemctl restart icinga2
3. Remove the Configuration File
Once the feature is disabled and the service is restarted, you can safely remove the configuration file. By default, the IDO MySQL configuration file is located at /etc/icinga2/features-available/ido-mysql.conf. To remove it:
sudo rm /etc/icinga2/features-available/ido-mysql.conf
4. Check for Any Remaining Dependencies
If you’ve customized your Icinga2 installation, check for any other scripts, cron jobs, or configuration snippets that might depend on the IDO MySQL configuration.
5. Optional: Clean Up Database and User
If you are sure that you won’t be using IDO MySQL again and want to clean up the MySQL database and user created for Icinga2, you can do so using the MySQL command line:
/opt/lampp/bin/mysql -u root -p
Then run:
DROP DATABASE icinga2;
DROP USER 'icinga'@'localhost';
Replace 'icinga'@'localhost' with the actual user and host if different.
6. Verify the Service Status
After making these changes, ensure that Icinga2 is still functioning correctly:
sudo systemctl status icinga2
7. Backup Considerations
If you might need to revert these changes later, consider backing up the configuration file instead of deleting it:
sudo cp /etc/icinga2/features-available/ido-mysql.conf /etc/icinga2/features-available/ido-mysql.conf.backup
This step allows you to retain the original configuration settings which can be restored easily if required.
