CentOS upgrade.

By | August 26, 2019

Updating CentOS Linux is pretty simple procedure. Recently I updated one of my CentOS VM from one release to another and I want to share this information and keep it for future reverences. I did it though terminal window and started with checking initial release version:


# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)

So according to mirrorlink http://mirror.centos.org/centos/ from /etc/yum.repos.d/CentOS-Base.repo repository file it is not the latest version, so I started my update process:


# sude yum update

When update was competed I checked the release version again and I saw that it is higher 7.6.1810 and the latest one which could be found in repository:


# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)

Also check-update shows that no updates are available:


# sudo yum check-update
Loaded plugins: fastestmirror
