We run a project administration system web application call 'Redmine'. I have been trying for ages, without success, to get SELinux and Passenger -- essentially a fast-cgi replacement Apache module built specifically for Rails -- to run together.
I have found that the latest versions of the Passenger Apache module are supposed to work on CentOS-6, but not with the stock kernel.
See: https://www.phusionpassenger.com/library/walkthroughs/deploy/ruby/ownserver/...
My questions are: Are there really really grave implications of using the kernel-ml form epel repo to get a sufficiently modern kernel to finally get Passenger and SELinux to work together? And are those implications more grave than simply disabling SELinux on that server entirely, which is the only other choice.
TIA
