Installation/Helyx-OS/CentOS SL RHEL
1 Introduction
This page is dedicated to explaining how to install Helyx-OS in:
- Community ENTerprise Operating System, aka CentOS.
- Red Hat Enterprise Linux, aka RHEL.
- Scientific Linux, aka SL.
In theory, all of the above follow the same versioning. Therefore, at the time this page was first written, RHEL, CentOS and SL were all at version 6.7.
If you do not yet feel comfortable using Linux, then perhaps you better first read the page Working with the Shell and train a bit with the shell/terminal environments, so you can have a better perception of the steps shown below.
2 Copy-Paste steps
A few notes before you start copy-pasting:
- Lines that start with # don't have to be copy-pasted. They are just comments to let you know what's going on.
- One wrong character is enough for breaking this guide, so make sure you can read the characters properly or that the installed language system does not break the copied characters!
2.1 Helyx-OS v2.3.1
Valid versions: 
In this section are the instructions meant for Helyx-OS v2.3.1.
Note: If you have the 64 bit architecture of CentOS/RHEL/SL, perhaps it's best to follow the official installation instructions: Installation of the Latest 64 Bit Linux Binaries @ Github
As for 32-bit, it's not possible to provide simple instructions for it, due to the following reasons:
- The EPEL repositories for CentOS/RHEL/SL 6.x only provide VTK 5.8 and Helyx-OS requires at least VTK 6.1.
- The EPEL repositories for CentOS/RHEL/SL 7.x provide VTK 6.1, but i686 is not in the primary tier for supported architectures, therefore the EPEL repositories are only available for 64-bit platforms.
