The version of Bind in the normal Red Hat / CentOS repositories is a little out of date. To get more up-to-date versions (9.7.4 at the time of writing) use the Centalt and EPEL repositories.
Create the following file:
vi /etc/yum.repos.d/centalt.repo
And add the following to it:
[CentALT]
name=CentALT Packages for Enterprise Linux 5 – $basearch
baseurl=http://centos.alt.ru/repository/centos/5/$basearch/
enabled=1
gpgcheck=0
Next install the EPEL repository with:
rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
To install Bind 9.7.4:
yum install bind
To install the chroot jail version of Bind:
yum install bind-chroot
