Rollback CentOS updates with RPM and YUM
Hold on Cowboy
This blog post is pretty old. Be careful with the information you find in here. The Times They Are A-Changin'
Every server administrator likes to sleep at night and every server admin knows server updates could prove disastrous. Just found out that RPM and Yum allow you the ability to rollback an update if some how it sent your system into a choking fit.
In your /etc/yum.conf add this in there somewhere tsflags=repackage
This will repackage all your old files from the package (including config files) and store them in /var/spool/repackage
Also add the file /etc/rpm/macros and place this in that new file %_repackage_all_erasures 1
When things go wrong
If you want to rollback changes to a certain time, then just issue commands like
rpm -Uhv --rollback '9:00 am' rpm -Uhv --rollback '4 hours ago' rpm -Uhv --rollback 'december 25'
Untested Yet
This is just stuff I’m reading, I have yet to test this under fire, maybe I’ll play around on a test server
