I am editing the httpd.conf file and adding ‘SSLCompression Off’. When I do that, the Apache service does not start. The system log does not register any meaningful error.

The problem is that you are trying to use cipher suites not supported by your openssl version. Check by running:
openssl ciphers -v and check that the ciphers you have included in apache are in the list. I also recommend you upgrade to openssl-1.0.1
