Hi

I am still learning Linux and doing quite a bit of reading/research.
I've recently been taken on a new job role and have inherited 2 Linux servers running BIND

The version running is 9.11.4 and requires upgrading.

I ran the following command

sudo yum update bind

It will not update the a newer/secure version (No packages marked for update)

How do I update the current BIND to a newer or latest version?

What is the process? What are the commands?

If I need to add a repository? where I go to get the repository info for BIND?
I read I may have to add a the repository to CentOS-Base.repo ?

Please can someone help?

Thank you

CentOS 7 went out of support 2 years ago. There are no more updates.
Not for BIND, not for anything.
You have the right command, but there aren't any more updates for that OS.

CentOS 8 went out of support last year. It is recommended to go to CentOS 9 if you want to stay with CentOS.

Be Aware: CentOS is no longer 100% compatible with Redhat. You may want to look at AlmaLinux or RockyLinux
these are true Redhat clones. In fact, you can install BIND on almost Linux distro.

9.11.4 is the latest from the default repos, you don't need a newer/secure version because CentOS7 is based on Rhel7 and Redhat supports all the packages in a Rhel version with back-ported security updates until the end of life of a Rhel version. If there are updates available you just have to do a "yum update" as you already did.

CentOS 7 still has support since Rhel7 hasn't reached end of life yet.
June 30, 2024 Rhel7/Centos7 will be end of life, unless you buy an ELS license if you have Rhel7.

No you don't need to build a new server, Centos7 is still in support June 30, 2024 and the all the security updates for the packages are back-ported during the life time of that version. Didn't you read my first reply?
