Re: How To Upgrade 7.1 to 7.3 via yum



I've upgraded 7.1 to 7.3 on several production servers. I first did a traditional upgrade on a test copy of one of the servers. I then compared the old and new package lists. I rebuilt several customized packages because they were "older" than the 7.3 versions. I installed the C library on the production servers. This caused SSHd not to do initgroups() on login the next morning. Restarting SSHd fixed the problem. I installed the custom packages on the production servers. I installed the packages that were added during the traditional upgrade. I installed the packages from CD 1 using rpm -Fvh a*.rpm, ... rpm -Fvh z*.rpm, rpm -Fvh *.rpm. I did the same with CDs 2 and 3. Occasionally I had to install packages from a different CD to satisfy dependencies so I just scp'd them to my account on the server from my workstation. The one problem that bit me was that the default /etc/identd.conf changed to enable encryption of ident information. I use ident authentication on my PostgreSQL server which is needed for web applications so that broke. Once I figured out that identd was the problem, I just had to change the default setting back.

I also upgraded 7.1 to 7.3 on my home firewall using apt-get. I had a problem with gdk-pixbuf-gnome - apt-get wanted to remove it. I wound up copying and pasting the "upgraded packages" list into separate apt-get commands a line at a time. Eventually I figured out that if I specified gdk-pixbuf-gnome on the apt-get command it would upgrade it instead of removing it. My one mistake was not re-running LILO. Naturally I didn't have a boot disk available. I had to make a boot floppy on a 7.3 system at work and figure out which partition was my root partition via trial and error.

My experience with yum leads me to believe that it doesn't resolve dependencies well when many packages are involved. Apt-get is a much better tool for system upgrades.

My $0.02 USD,
