Disabling SELinux

===To disable SELinux===

0. Running getenforce on the terminal will output 'Enforcing':
    $ usr/sbin/getenforce
    $ Enforcing...

1. When I checked /etc/selinux/config, it read
*deliberately omitted spaces b/w # and first character*

    # This file controls the state of SELinux on the system.
    # SELINUX= can take one of these three values:
    #       enforcing - SELinux security policy is enforced.
    #       permissive - SELinux prints warnings instead of enforcing.
    #       disabled - No SELinux policy is loaded.
    SELINUX=enforced
    # SELINUXTYPE= can take one of these two values:
    #       targeted - Targeted processes are protected,
    #       mls - Multi Level Security protection.
    SELINUXTYPE=targeted

2. I changed 'SELINUX=enforced' to read 'SELINUX=disabled'.

3. I rebooted the system, and ran the command again.
    $ usr/sbin/getenforce
    $ Disabled

4. I headed over to localhost/iiab and the Wikipedia page worked!
