All of our name servers I use are virtual servers and we add them into our network as OpenVZ VPS systems. Here is the setup I use for setting up a Bind server on an OpenVZ VPS with CentOS 5.
Setup the Open VZ VPS and get into the VPS:
vzctl create 1031 --ostemplate centos-5-i386-default --config vps.basic vzctl set 1031 --hostname ns4.aztecsoftware.net --save vzctl set 1031 --ipadd 10.0.0.31 --save vzctl set 1031 --nameserver 10.0.0.30 --save vzctl start 1020 vzctl enter 1020
Now that you are in the VPS update the OS and get Bind updated:
yum -y erase bind* caching-nameserver rm -rf /var/named yum -y install bind* yum -y update
Get the DNS key through dns-keygen (copy the key):
/usr/sbin/dns-keygen
Start the DNS Setup:
touch /var/named/chroot/etc/named.external.zones touch /var/named/chroot/etc/named.internal.zones cp /usr/share/doc/bind-9.3.4/sample/etc/named.* /var/named/chroot/etc/ cp /usr/share/doc/bind-9.3.4/sample/var/named/named.root /var/named/chroot/var/named/ chown named:named /var/named/chroot/var/named/named.root
I am not going to get into details on how to setup your named.conf — as mainly this is a command reference for myself in the future (aren’t I selfish). However, here is my list:
- Remove the Caching Server View (localhost_resolver) because we do not need it because we are not using the caching only name server
- Setup the zones for internal and external and point them to the touched files above (named.external.zones and named.internal.zones)
- Make sure you are not in a position where you can fall subject to the cache poison.
vi /var/named/chroot/etc/named.conf
