But to be clear...I had to google SELinux and don't know what these mean or do.
Ok, then you'd better disable SELinux just to make things easier first.
Try this; from console, type setenforce 0
to loosen it a bit, then restart your bind. If your your bind up, then SELinux was the thing that prevented your bind to get started.
Now, put SELinux into a disabled state; edit the /etc/selinux/config
and change the value of SELINUX=enforcing
Hope it may help.
