How to add repos to Linux

Yum repos are used to install and update various software’s in Linux. Sometimes it happens that you are not able to find a software in that repo and you need to add a new repo to install that software.

Let’s say you want to add a repo in Linux. First step will be that you will download the repo by the following command

#wget http://apt.sw.be/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

After that you will install this repo to your existing server by the following command

#rpm –ivh -release-0.3.6-1.el5.rf.x86_64.rpm

So in this way the repo will be installed to your server 

If you want to add a 3rd party repo then you have to follow the following procedure 

Goto /etc/yum.repos.d

Let’s suppose your repo is named as “virtual”. So we will use 

#vi virtual

And then add the following lines 

[virtual]

name=Virtual for RHEL/ CentOS $releasever - $basearch

baseurl=http://foo.nixcraft.com/centos/$releasever/$basearch/

enabled=1

gpgcheck=1

gpgkey=http://virtual.nixcraft.com/RPM-GPG-KEY.txt

Here first argument is the name of your repo, second tells us about the string for your repo name, third is the directory index of your repo, enable when 1 means it’s ON and when 0 means its disabled, gpgcheck is the security feature in repos
