Up2date on CentOS 4.2

[hci]

I have a box running CentOS 4.2 release. How do I safely up2date it to 4.4 or however that works?

First you make sure to have the proper excludes set up in /etc/yum.conf:

exclude=httpd* mysql* php* perl* apache* mod_* MySQL* *ftp* exim* sendmail* php* da_*

You can decide for yourself if you want the kernel excluded as well; if you do, add to the above line kernel*.

Then

# yum update yum
# yum update

Don't type the # marks; they're just to show you that you do this as root.

Isn't the kernel the main thing I want updated? For security etc what do I want updated? I also likely want to exclude spamassassin?

Thanks!

yum update only updates what was installed from RPMs. To see the entire list:

# rpm -qa

Sure you may want to update the kernel, but you may want to do it when you can be around, instead of every night automatically, in case (for example) it doesn't automatically install all the needed kernel modules (we had this problem with a client this evening).

You need to update a lot more than the RPM stuff; you should run the customapache stuff quite often as well. And there are other programs to update manually, too.
