	This document provides a quick methodology for installing RT 4.4.2 on CentOS/RHEL 6.9 for an internet-connected server.		This document provides a quick methodology for installing RT 4.4.2 on CentOS/RHEL 6.10 for an internet-connected server.

			CAUTION: While this document has been upgraded for CentOS 6.10, you cannot use this method to install RT 4.4.3 directly - there is an issue with the web install on RT 4.4.3. I've asked Best Practical to look at the issue. It would appear that the PGP key for RT-4.4.3 is not certified, and the web install fails during attempts to follow the method below. I can confirm an upgrade to RT 4.4.3 is possible after following this install, but with the PGP key issue, I do not recommend the upgrade until Best Practical resolves the PGP certified key issue.
