Here I will describe some basic steps for doing fresh install of chrooted bind version under Centos 6.
Install the rpm packages
yum install bind bind-chroot bind bind-libs
Move the necessary directories
mv /var/named/named.* /var/named/chroot/var/named/ mv /var/named/{data,dynamic} /var/named/chroot/var/named/
This part is very important, cause if you don’t do this, bind won’t start.
Also if /var/named/chroot/var/named/dynamic directory is missing you will most likely experience strange CPU starving problems. In my case named was eating lot of CPU without doing anything.
Edit /etc/named.conf and fine-tune little bit
Also I removed the IP/port bindings from named.conf in order the server to listen on all of my interfaces. By default it listens only on localhost.
Add the following section in /etc/named.conf
view "external" { allow-transfer {none;}; zone "." IN { type hint; file "named.ca"; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; zone "blog.gryzli.info" IN { type master; file "blog.gryzli.info.zone"; }; };
Create the zone file blog.gryzli.info.zone
$ vim /var/named/chroot/var/named/blog.gryzli.info.zone
$TTL 60M @ IN SOA ns1.gryzli.info. root ( 42 ; serial (d. adams) 3H ; refresh 15M ; retry 1W ; expiry 1D ) ; minimum IN NS ns1.gryzli.info. IN NS ns2.gryzli.info. @ IN A 1.2.3.4 www IN CNAME @
Finally we must restart named:
/etc/init.d/named restart
