Before installation
Use a supported Linux image and a plan that meets the application requirements. Back up any existing workload. Confirm DNS, free disk space, and required ports before approving the installer.
Install from the client panel
- Open the purchased VPS and choose Install application.
- Select cPanel & WHM and review compatibility, estimated time, and the exact plan.
- Confirm the server identity and backup warning.
- Follow installation progress from the task page. Do not run the installer twice.
The VPS can show Active while application setup is still finishing. Wait for Ready or review the reported result before using it.
First setup
Use a supported fresh operating system, root access, a static public IP, and working hostname DNS. A valid cPanel license is required. cPanel has no supported uninstaller; removing it requires an OS reinstall, which erases the server.
Troubleshooting
Check the installation result, VPS power state, DNS, required ports, free storage, memory, service or container status, and the first relevant log error. Preserve logs before retrying. If the task needs attention, open a support ticket instead of rebuilding the VPS.
Backup and recovery
Use WHM backups for accounts and keep system configuration, DNS, license, and recovery copies outside the VPS. Test account restoration before production use.
Official documentation
Review the current cPanel & WHM documentation before production changes.
