Running CloudLinux 7 and CloudLinux 8 on an OVH server is a common configuration. CloudLinux is designed to provide additional stability and security enhancements for Linux servers, making it a popular choice for hosting providers and server administrators.

Here are some general steps you can follow to set up CloudLinux on your OVH server:

1. Order and Provision a CloudLinux License:

   • Purchase and obtain the CloudLinux license from the CloudLinux website or through a CloudLinux reseller.

2. Backup Your Data:

   • Before making any major changes to your server, it's always recommended to back up your data and configurations to prevent data loss in case of any unforeseen issues.

3. Install CloudLinux:

   • If you're setting up a new server, follow CloudLinux's installation instructions. This typically involves booting the server from a CloudLinux installation media and following the installation prompts.

4. Activate CloudLinux License:

   • After installation, activate your CloudLinux license using the provided activation key. This is usually done through the CloudLinux Manager or by using command-line tools provided by CloudLinux.

5. Configure LVE Manager:

   • LVE (Lightweight Virtual Environment) is a key feature of CloudLinux that allows you to control and limit resource usage for individual accounts. Set up LVE Manager to manage these limits.

6. KernelCare (Optional):

   • Consider installing KernelCare for automated kernel updates without rebooting. This helps ensure that your server is always running the latest security patches.

7. Configure Web Servers and Databases:

   • Set up and configure your web server (e.g., Apache, Nginx) and databases (e.g., MySQL, MariaDB) as per your specific requirements.

8. Install and Configure Control Panel (Optional):

   • If you're using a control panel like cPanel, Plesk, or DirectAdmin, install and configure it according to the specific instructions for CloudLinux.

9. Monitor and Manage Server:

   • Regularly monitor the server for performance, resource usage, and security. Tools like top, htop, and CloudLinux's LVE Manager can be useful for this.

10. Security and Firewall Configuration:

    • Implement security best practices and configure firewalls to protect your server from unauthorized access.

11. Regular Backups and Updates:

    • Set up regular backups and ensure that your server is kept up-to-date with security patches and software updates.

Please note that the specific steps and configurations may vary depending on your exact requirements, the control panel you're using (if any), and other factors. Always refer to the official documentation for CloudLinux and any other software you're using for the most accurate and up-to-date instructions.
