That's a very bad advice.

SELinux is very useful as a security measure in Linux, and since RHEL5
(and CentOS 5) it has reached a good balance in terms of usability vs.
security. I admit that making it work under the previous versions was
very tricky, but with CentOS 5 it just works.

Of course you eventually have to tweak it to make it work for 3rd
party programs (such as in the OP's case). In that case, this page may
help you do it:

SELinux is certainly complex and there is a steep learning curve, but
it's certainly worth learning how to use it and keeping it enabled.
