latest patch level

Post by Anju Singh » 2018/12/06 04:06:07

Hi All,

I have been working with Redhat for quite a while. I am new to centos. Can I know what is the latest patch level for Centos 6 and 5 ?

I have some servers with different patch levels -

CentOS release 5.5 (Final) - 2.6.18-194.el5
CentOS release 5.8 (Final) - 2.6.18-308.8.2.el5
CentOS release 6.2 (Final) - 2.6.32-220.4.2.el6.x86_64
CentOS release 6.5 (Final) - 2.6.32-431.el6.x86_64

CentOS is a rebuild of RHEL so it has the exact same patch levels.

CentOS 5 is dead and should no longer be used. The last version of CentOS 5 was 5.11. The last version of CentOS 5 went End Of Life in March 2017 and there will be no further updates to it and it should no longer be used or deployed. Migrate to something newer ASAP.

CentOS 6 goes EOL in just under 2 years time. The current version is 6.10 and uses a 2.6.32-754 series of kernels. It goes EOL in 2020.

CentOS 7 is the most recent version and the current 7.6 was released a few days ago. It goes EOL in 2024.

All of your servers listed are massively out of date and need `yum update` to current. They are dangerous to run in their current form as you are missing more than 5 years of patches from the newest one you list (6.5 was Dec 2013). The CentOS 5 servers are all EOL and need to be reinstalled with a newer version ASAP.
CentOS 5 died in March 2017 - migrate NOW!
