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!

  • Absolutely fantastic article! Got my yum working instantly with these instructions! Keep up the good work!

  • This works nicely, but it doesn't really give you an up-to-date system. "make" is still a buggy version and requires a newer version of glibc to update it.

  • Didnt work:

    [jyl@fjsoftllc yum]# yum -y update

    Is there a fail-over server?

  • This is great and the set up worked flawlessly. One question - what does 'yum -y update' actually do? I am watching the updates go by and /var filling up and wonder if all these are actually updates of current libraries/applications. I say that partially because I tried 'yum search "enter package here"' and it seemed to do the same as 'yum -y update'. I would like to selectively search and install packages.

  • Thanks. Very useful.
    Do you know if these updates are identical to those from rhn?

    Step #2 & #3 need adjustments:
    prompt> wget http://yum.baseurl.org/
    download/2.0/yum-2.0.tar.gz
    prompt> gunzip yum-2.0.tar.gz
    prompt> tar xvf yum-2.0.tar
    prompt> cd yum-2.0
    prompt> ./configure
    prompt> make
    prompt> make install

    continue w/ step 4.

  • Wicked article on converting from using RHN to YUM. Saved me a lot of time and effort and money re-registering our server with RH.

    Thanks

  • Nice work - thanks. This info is surprisingly hard to find so I was happy to find it. The first phase has gone very well and although I have not yet dared to execute the last part all indications are that it will go well.

  • Thank you,
    the previous admin mucked the yum to overcustomized it ... now I able to recovere the OS back to the official RHEL3.

  • I cannot find a place to download yum. It appears that all links are obsolete. May someone provide any working links? Thanks, Sam Feb 24, 2010

  • Thanks, saved me lots of time. My Yum was broken and I needed php-mcrypt for a script I'm makin' ;)
