Issue Plesk DNS Server (BIND) Wont start

[BON]

Hello,

My DNS server wont start. I have just noticed this, first I thought the problem was with the domain registrar.

The server throws the following error:

[root@core ~]# systemctl status named
● named.service - Berkeley Internet Name Domain (DNS)

What could be causing this and how do we fix it?

Thanks,

Hi,

Could you exec "plesk repair dns", then restart "named" and check logs?

Throws an error when I try to restart it. Plesk DNS repair does literally nothing.

What should I try next?

 

[vzhidkov]

Check the status of named-chroot service and try to restart it.

Nope. It's also down. Cannot restart.

Try solution from article named-chroot does not start: dns_rdata_fromtext: syntax error

 

[AYamshanov]

Let's try find root of "syntax error" issue, run command: /usr/sbin/named-checkconf -t /var/named/chroot -z /etc/named.conf

And post please output of `systemctl list-unit-files | grep ^named`.

Wont it be better if I removed all the domains? And maybe erase all the DNS zones if theres a command for that?

[AYamshanov]

I found this kb: Unable to start named: loading from master file failed: file not found but it's applicable for Plesk 12.5. Could you try the solution from KB?

And you should restart "named-chroot" service because it is enabled, not "named".

 

[AYamshanov]

hmm.... but anyway this is strange, it is should be fixed by "repair" tools...

Have you got any settings between texts in file /var/named/chroot/etc/named.conf?

// -- PLEASE ADD YOUR CUSTOM DIRECTIVES BELOW THIS LINE. --
// ...
// -- END OF YOUR CUSTOM DIRECTIVES. --

I tried the command like you said. Same thing.

# systemctl restart named-chroot

It is empty. Theres a bunch of stuff generated by Plesk at the top and bottom of it.



Is there a way to completely cleanse the DNS zones, remove the domains and see if it will cause errors when I add them again?
