Recently while installing Apache 2 web server on a Fedora Core 4 machine, I ran into some very peculiar problems.

Apache would compile cleanly, install perfectly but when I would start the web server it would fail complaing about, failed to load shared library (some ldap and others).

After much hunting and googling, i found that it’s this SELinux (Security Enhance Linux) stuff that’s creating problems.

If you too have faced a similar problem, just switch off SELinux by modifying the file /etc/selinux/config (file path might be specific to FC4), and changing the line SELINUX=encforcing to SELINUX=disabled
