Web Server Installation on CentOS 6¶

This is a work in progress. We'll write documentation on Appion Web Server Installation on CentOS 6 as we go.

Before you start, make sure you have CentOS 6 installed on your computer. Note that upgrade CentOS 5 to CentOS 6 can damage existing filesystems and operating systems as described in CentOS Migration Guide. That's why we recommend starting with a fresh install of CentOS 6. The following links provide excellent step by step guide on how to install CentOS 6 Linux from scratch on a new machine:
