15, install yum on RHEL 4

I got this tip from Babar Haq’s Blog with a little modification since I am using RHEL 4.

1. Download yum by using wget

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

2. Install the rpm

# rpm -ivh yum-2.0.8-1.noarch.rpm

3. Configure /etc/yum.conf to use compatible repository

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1

[base]
name=CentOS-$releasever – Base
baseurl=http://mirror.centos.org/centos/4/os/i386/
gpgcheck=1

[updates]
name=Red Hat Linux $releasever – Updates
baseurl=http://mirror.centos.org/centos/4/updates/i386/
gpgcheck=1

4. Download and install the CentOS GPG Key

# wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-4

# rpm –import RPM-GPG-KEY-CentOS-4

5. Test yum to see if it works (I tested by running full update on my machine)

# yum update

16. when installing websphere 7.   the installation precess is always blocked, importconfigarchive

 

Because Ubuntu uses dash as its default shell instead of bash, this breaks WAS’ installation routine when it comes to setting up the domain profile. (It hangs for ages at 31% when executing the importConfigArchive script, and the fails silently, which is nice.) To fix this you need to relink back to bash (according to Graham, this actually fixes a number of third-party software installation issues):

sudo -i cd /bin unlink sh ln -s /bin/bash sh
