Yum Server Configuration

I have seen most of the people who try to install Oracle RDBMS/Oracle Grid Infrastructure on Linux OS very first time or so get stuck at the stage of RPM package validation and while installing them one by one at OS level due to dependencies among them. So to overcome from such situation and to do all RPMs/packages installations in an easy way you should configure yum server on a machine and let it do all the downloading/installation of all packages itself for you.

To configure yum server, first of all we need to identify the installed Linux OS version and it's corresponding public yum repository.

[root@localhost ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)

[root@localhost ~]# cd /etc/yum.repos.d/

Now we will be creating public-yum-el5.repo named file with following details to cofig the yum server pointing public yum repository.

[root@localhost ~]# vi public-yum-el5.repo

[el5_u4_base]
name=Enterprise Linux $releasever Update 4 installation media copy ($basearch)
baseurl=http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/4/base/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=0
enabled=1


Note : Make sure you have changed the value of enabled to 1 from 0, Save and Exit;


List repository packages in Oracle Linux as shown below now.

[root@localhost ~]# yum list

Now we are ready to install any packages required with following yum install command:

[root@localhost ~]# yum install [package_name]

For example, I wanted to install elfutils-devel packages but it has dependent packages to be installed first. As we have already configured the yum server then we just need to provide some start string of the package to be installed ending with asterisk(*) then it will automatically download/install all its dependent packages along as follows:

[root@localhost yum.repos.d]# yum install elfutils*
Loaded plugins: rhnplugin, security
This system is not registered with ULN.
ULN support will be disabled.

Finally, you saw all dependent packages got installed in such an ease way by configuring yum server.
