How to Undo or Redo a Yum Install on CentOS and RHEL

One of the most important and useful features added to YUM Package Manager (from version 3.2.25 ) is the ‘ yum history ’ command. It allows you to review a full history of yum transactions that have been run on a system.

It shows the dates and times when transactions were performed, whether the transactions succeeded or were aborted, the number of packages affected, and so much more.
