Introduction
CloudLinux OS is widely used in shared hosting environments to improve server stability, security, and resource isolation. Converting a cPanel server from CentOS to CloudLinux is a simple process that takes only a few minutes.
Prerequisites
Before proceeding, ensure:
- Root SSH access to the server
- Existing cPanel installation
- Valid CloudLinux OS license or trial activation key
- Server backup recommended before migration
Implementation
Step 1: Obtain CloudLinux License
Get an activation key by:
- Purchasing a license
- Using a trial subscription
Step 2: Download the Conversion Script
Run:
wget http://repo.cloudlinux.com/cloudlinux/sources/cln/cpanel2cl
Step 3: Run the Conversion Script
Using activation key:
sh cpanel2cl -k <activation_key>
If the license was purchased directly from cPanel:
sh cpanel2cl -k
Step 4: Reboot the Server
reboot
Step 5: Rebuild Apache
After reboot, rebuild Apache using EasyApache:
/scripts/easyapache --build
Verification
After rebooting, verify that the server is running the CloudLinux OS kernel with LVE enabled.
Conclusion
Installing CloudLinux OS on a cPanel server improves stability and resource management for shared hosting environments by isolating users and controlling server resource usage.
