What are the system requirements of InterWorx Control Panel?

InterWorx Control Panel runs on a variety of systems and hardware including Virtual Private Server (VPS) systems.

Minimum System Requirements

  • Processor: 1.1 GHz

  • Disk Space: 20 GB minimum; 40 GB recommended

  • Memory: 1 GB minimum RAM with 3 GB minimum swap

    • If the system has more than 1 GB RAM, the RAM to swap ratio should be as follows:

      • 2 GB RAM should have at least 4 GB swap

      • 4 GB - 8 GB RAM should have the same amount of swap as RAM

      • If more than 8 GB of RAM, there should be at least 4 GB swap

If using a VPS system, the above requirements pertain to the VPS instance, not the host machine, itself.

Supported VPS Systems

The following are some examples of known supported VPS providers.

Warning

InterWorx does not support containerized environments, including Docker or LXC.

Note

While InterWorx will install and work on both Digital Ocean and Azure, both of those services block port 25, which is the port that the mail service included with InterWorx (Qmail) uses. An outside mail provider will be required in those environments.

Supported Operating Systems

Note

While CloudLinux is a supported Operating System, Interworx must be first installed on CentOS 7, RHEL 7 or 8, AlmaLinux 8, or Rocky Linux 8. Once InterWorx is installed, converting to CloudLinux can be completed via the CloudLinux plugin.
