If you have issues with cPanel running CentOS5 with BIND then the easiest way is to downgrade BIND to 9.2.4

The reason you’re having trouble is because CentOS 5 uses bind-9.3 and CentOS 4 uses bind-9.2 – The changes between these versions is significant enough that cPanel won’t work with it properly.

For instance by default there is no /etc/named.conf file created when bind-9.3 is installed and the default named.conf file for bind-9.3 is significantly different than in older versions.

Until the code is updated to work with bind-9.3, I have found the workaround to be to remove bind-9.3 packages and install bind-9.2 packages as follows:
 

Log into your servers via SSH and firstly we BIND


yum remove bind-*

yum remove bind

Then we ll install the old BIND rpm’s from a mirror closed to you

rpm -Uvh –nodeps http://ftp.monash.edu.au/pub/linux/CentOS/4.6/os/x86_64/CentOS/RPMS/bind-libs-9.2.4-28.el4.x86_64.rpm
rpm -Uvh –nodeps http://ftp.monash.edu.au/pub/linux/CentOS/4.6/os/x86_64/CentOS/RPMS/bind-utils-9.2.4-28.el4.x86_64.rpm
rpm -Uvh –nodeps http://ftp.monash.edu.au/pub/linux/CentOS/4.6/os/x86_64/CentOS/RPMS/bind-9.2.4-28.el4.x86_64.rpm
rpm -Uvh –nodeps http://ftp.monash.edu.au/pub/linux/CentOS/4.6/os/x86_64/CentOS/RPMS/caching-nameserver-7.3-3.noarch.rpm

simlink this
ln -s ../../lib/libcrypto.so.0.9.8b /usr/lib/libcrypto.so.4

service named start

The –nodeps flag is tagged on because of dependency "libcrypto.so.4" for the bind packages.
IMPORTANT!

Run those cPanel SSH comands

/scripts/fixndc
/scripts/rebuildnamedconf

You’ll also need to edit /etc/yum.conf and add a line in the [main] section
 that starts "exclude=" or append to this line if it already exists "bind* caching-nameserver".

nano  /etc/yum.conf


This prevents yum from updating bind-9.2 to bind-9.3 and in the process breaking cPanel.
If you fail to do this when cPanel update is run BIND will get updated and the DNS functionality of cPanel will break.
I hope this helps shed some light on this anoying issue.
