InterWorx is a hosting control panel purely based on Linux. It relies on the RPM package system for distribution of InterWorx itself, as well as for handling various software packages for web hosting platforms. Hence, It strongly recommends to have an RPM-compatible Linux distribution for installation.

In this article, I'm explaning about the installation of this control panel on a CentOS 7 server which is a RPM compatible Linux distribution. Previously the installation on this OS wasn't supported. But I believe you guys will be happy to know that the new Interworx release version 5.1.5 is designed to support the latest RHEL/CentOS distribution.
InterWorx Control Panel runs on a variety of systems and hardware including Virtual Private Server (VPS) systems supported on OpenVZ, Virtuazzo, Xen and VMware. It is also supports CloudLinux platforms.

Minimum hardware requirements

  • Memory : at least 256 MB; 512MB is recommended
  • CPU : Pentium III 866 CPU
  • Disk Space : 512 MB; 1GB is recommeded


  • A linux server or a supported VPS systems as mentioned above with atleast minimum hardware requirements is needed.
  • A clean install of the RPM-compatible Linux distribution supported OS is needed.
  • A valid and active InterWorx Control Panel license key is required
  • UIDs 102 - 107 and GIDs 102 & 103 should be free to use.

Installation steps

1. Login to the server as root.

2. Download and run the installer script

sh <((curl -sL

This installation script will prompt you to proceed further. If you don't want to be prompted after each configuration step, you can run the downloader script as below:

I run the initial installer script to check the installation procedure one by one.

You will receive this prompt on initial setup. You can verify your OS settings ans press "enter" to proceed.
