Installing CloudLinux with OS conversion
CloudLinux is an operating system for servers used to host multiple websites. CloudLinux improves server stability, performance, and security.
ispmanager offers a module that allows converting AlmaLinux OS to CloudLinux.
OS conversion requirements
Server
- a virtual or physical server that supports hypervisor virtualization
- a virtual server must have the 'virtio' network card
Operating system
- 64-bit architecture
- AlmaLinux 8, 9, or 10
The wget utility is installed
If wget utility is not installed- Connect to the server with the ispmanager panel via SSH.
- Enter the following command in the terminal:
yum install wget
ispmanager panel
- web server is installed in the Software configuration section
CloudLinux license verions
- CloudLinux OS Legacy (Shared)
- CloudLinux OS Shared Pro
Only the features of the Legacy (Shared) version will work with the Shared Pro version. Other CloudLinux licenses do not include the required software and are not suitable for integration.
CloudLinux installation considerations
- Correct installation is not guaranteed if third-party repositories are enabled in the system.
- CloudLinux license activation by IP address is not supported for IPv6 addresses. Activate the license via IPv4 address or key.
- The OpenLiteSpeed web server is not supported after conversion.
