Installing Yum On RHEL 3

I had a RHEL 3 WS at my work place. It irritated me terribly as the machine was never updated and hence having very old versions of softwares. Therefore I decided to upgrade my RHEL WS 3 using yum.

From my work place, internet is only accessible through http proxy, that too with authentication. I tried using up2date by creating an account at redhat's site but it didn’t work( I thought you could update one machine using your redhat account).

The first problem I encountered was that there is no public repository to update RHEL machines i.e you have to pay for it. After googling for a while I discovered that CentOS offers public repositories and they work with RHEL 3 as well.

I downloaded latest yum rpm, installed it and configured it to use centOS repo. Every time I ran yum, it failed. It couldn’t

find repomd.xml file in the CentOS repositories I provided in yum.conf.

After struggling for some time, I discovered that I was accessing older version of repos through the latest yum. Therefore I

had to use an older version of yum with RHEL 3, since old repos do not support xml based updating.

Now I have a fully updated system. Following is the brief summary of the steps I took

1) Since I was behind a proxy I had to export environment variable http_proxy.

2) Downloaded yum-2.0.8-1.noarch.rpm from

http://linux.duke.edu/projects/yum/download/2.0/yum-2.0.8-1.noarch.rpm

3) Installed it using

rpm –i yum-2.0.8-1.noarch.rpm

4) Configured my yum.conf to look like this:

[main]

cachedir=/var/cache/yum

debuglevel=2

logfile=/var/log/yum.log

pkgpolicy=newest

distroverpkg=redhat-release

tolerant=1

exactarch=1

#base]

#ame=Red Hat Linux $releasever - $basearch - Base

#aseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/$releasever/$basearch/

[base]

name=CentOS-$releasever - Base

baseurl=http://mirror.centos.org/centos/3/os/i386/

gpgcheck=1

[updates]

name=Red Hat Linux $releasever - Updates

baseurl=http://mirror.centos.org/centos/3/updates/i386/

gpgcheck=1

5) Downloaded the gpg key for CentOS rpm packages from

http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-3

6) Imported the key like this:

rpm --import RPM-GPG-KEY-CentOS-3

7) Run “yum –y update”. Now Sit back and enjoy seeing your system being updated.

Enjoy!
