how i configure bind9 DNS Server?

[BlackMage]

how i configure on CentOS the bind9 DNS Server? systemd just says on start from bind9: "Failed to start Berkeley Internet Name Domain (DNS)". Where are stored the logs?

on start try it outputs only:

Does it have to be bind9? The 'dnsmasq' is, IME, easier to set up.

For logs, look at journalctl -xeu named.service and files under /var/log/

[BlackMage]

yes it should already be the bind9. can't it be that difficult to set up?

journalctl -xeu named.service

gives

Code: Select all

The problem with bind9 is that the log doesn't tell me anything that helps me.

Apart from that...

i know that centos 7.9-2009 supported until 30Jun2024, but i plan upgrade CentOS7.9 to CentOS8{i know that support is until 31. Dez. 2021, but only for the upgrade path), and then to RockyLinux8.5(supported until May 2029)

but first I want to get my DNS server working, okay?

Why won't you upgrade directly from CentOS 7 to Rocky 8?

Then look at Trevor's post and fix the problem causing the error message he highlighted.

I'm sure you already know there's no upgrade path from one major version to another - it's a complete reinstall.

[BlackMage]

???
no it should be easy possible with dnf upgrade

see here: https://www.tecmint.com/upgrade-centos-7-to-centos-8/

From the link: "should not be applied to a production server yet."
And if you read the comments you'll see many people have problems.
Your choice of course, but I think everyone here will advice you not
to follow this "tutorial".
