Software Requirements

You must have a clean/fresh installation of supported operating systems:

Minimal CentOS/RHEL/CloudLinux 6.x or CentOS 7.x installation. At this time, CentOS Web Panel currently supports the English version only. Both 32 Bit and 64 Bit versions are supported, where applicable.

Hardware Requirements

Minimum RAM (32 bit systems): 512MB

Minimum RAM (64 bit systems): 1024MB

Recommended: 4 GB+ RAM

Minimum Disk (Any): 10GB+

If your server will be responsible for multiple services (web, database, email, DNS, etc), the added memory will be used to prevent system failure when multiple processes are using memory. Added CPU resources are recommended for this configuration, also.

Additional Steps
