How do I upgrade to Redhat Enterprise Linux server to v.5.5 from 5.4 or earlier version?
The new update RHEL 5.5 release features new hardware platform enablement, expanded virtualization capabilities and enhanced interoperability. You can simply upgrade it using the yum command:
WARNING! Make a backup - it cannot be stressed enough how important it is to make a backup of your system before you do this.Most of the actions listed in this post are written with the assumption that they will be executed by the root user running the bash or any other modern shell.

# uname -a
# yum update

what? yum update and that’s it???
Yes, all you’ve to do is type one single command and you are done.
question then, if I’m running CentOS 5.2.. I can just keep yum updating all the way up to 5.5? I’ve always assumed you had to do much more work than that to go from release to release with CentOS. Is CentOS a ‘rolling release’?
CentOS will roll out them within 3-4 weeks time. Once rolled out simply type the same command.
HTH
Vivek, I think you should’ve mentioned that the yum update command works only if you have a valid RedHat Network subscription and if your repository list is configured properly… the command will never work if RHEL is not able to connect to Red Hat’s servers
A coworker saids that by inserting apel,rpmforge and utterramblings repos they will take care of RHEL updates/upgrades without RHN support.
Is that true?
Thanks
We have 100s of server running nothing bur RHEL 4 and 5 with our own proxy server. Some of my clients have over 2k+ server running nothing but RHEL. Why anyone will install RHEL with RHN (which provides security update) is beyond me? If you cannot afford RHEL go for Centos.
Did you mean “without RHN” ? ;)
This process is broken (again).
Error: failed to retrieve repodata/filelists.xml.gz from rhel-x86_64-server-5
error was [Errno -1] Metadata file does not match checksum
Vivek:
Not sure I understand your point.
“We have 100s of server running nothing bur RHEL 4 and 5 with our own proxy server. Some of my clients have over 2k+ server running nothing but RHEL. Why anyone will install RHEL with RHN (which provides security update) is beyond me? If you cannot afford RHEL go for Centos.”
Can you elaborate? Are you against installing RHEL with RHN?
Hi,
Can i use “apt-get” ?
Can I use apt-get?
No. Unless you really like horribly broken systems that have two conflicting package management systems stepping all over each other.
If you insist on using apt, you should run a dpkg based system like Debian or Ubuntu. If you are going to use an RPM based system like Centos, Red Hat, or SuSe use tools based on RPM.
Hi,
I Have installed Redhat 5.4, can i upgrade my server to CENTOS 5.5 ?
Thanks
Nop. You remove RH and then install CentOS 5.5
Will this method work even if upgrading between major versions (i.e. version 4 to version 5)?
I think no problem and you can upgrade
