Linux – Cannot start BIND9

You haven't got A records for your nameservers ns1.main.com and ns2.main.com. The named-checkzones hasn't worked as it is warning you that you haven't got A records for your nameservers:

zone main.com/IN: NS 'ns1.main.com' has no address records (A or AAAA)

zone main.com/IN: NS 'ns2.main.com' has no address records (A or AAAA)

So you need to add the following to your main.com.db file:

ns1           IN    A    174.143.182.1
ns2           IN    A    174.143.182.2

Without these glue records the whole thing won't work.

Also your SOA record for main.com is wrong. It should be:

@       IN      SOA     ns1.main.com. info.main.com.

It didn't fail in the named-checkzones because you have a main.com A record and BIND assumed that was the name server record.

To stop bind, the scripts use rndc stop command. Check if you run it by hands if you have the same answer. If it is the case, check netstat -pnlt | grep 953 if bind is waiting for your connections check if your keys in /etc/bind/rndc.key are the same in /etc/bind/named.conf

If you change the keys, you must kill the process as it will not be stopped by rndc, and then restart bind
