I was intrigued to hear of Moodle LAMS integration and have recently installed LAMS on a CentOS 4 (RedHat Enterprise Linux 4 (RHEL4) clone) for evaluation purposes.
The installation includes Apache-LAMS integration so that both LAMS and Moodle can be installed on the same server with both available on the standard webserver port 80.
In an attempt to help others I have published my installation experiences in a blog at http://www.linuxtraining.org.uk/blogger1.html
