Hi folks,
I have a production server that's currently running 5.0 with all
updates. What's the easiest, or perhaps best way to upgrade it to 5.1,
with minimal down time? The downtime is critical, so I need to have it
be a short as possible. I can live with an hour or two, but larger is
going to be a pain.
Suggestions?

If you're unsure if you actually are running centos 5.1, run 'rpm -q centos-release' and you should see 5.1.0- in the release string. -- During times of universal deceit, telling the truth becomes a revolutionary act.

So probably all you have to do is reboot to the latest kernel. Unless you've changed the default yum repo files to stay at 5.0 for some reason, you should already be at 5.1.

You can repeat the 2nd command if it doesn't complete or if some time passes before you get around to doing the yum install which will go quickly with all the packages already downloaded. You really only have downtime if you need to reboot and you only need to reboot if you pick up a new kernel in the update. -- Les Mikesell lesmikesell at gmail.com
