How to create yum repository in Redhat Linux ?

The Yellowdog Updater Modified (YUM) is an rpm package management opensource tool which is available for Redhat Linux  and other Linux flavors.In earlier days, its very difficult to install packages in Linux systems since it will ask for many dependencies.After yum introduction,its become very simple and yum has algorithm to select all the dependencies automatically once you configured the yum repository.

After reading this article you will get fair idea about installing yum packages,configuring yum repository  and installing  new packages using yum repo.

Install yum packages from Redhat Linux OS DVD. 

     # rpm -i deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm 
# rpm -i python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
# rpm -i createrepo-0.9.8-4.el6.noarch.rpm

Configuring  Yum repository.
       1.Create the Directories:
          mkdir -pv /home/repo/yum

       2. Copy the RPMs from the CDs/DVD to /home/repo/yum

       3.Create the base repository headers:
         createrepo -v /home/repo/yum

       4.Go to /etc/yum.repos.d and create file with any name 
          (i.e repo would be fine with .repo extension)

[root@localhost yum.repos.d]# cat myyum.repo

That’s all.We have successfully created the yum repository .

  1. Thanks for sharing such a nice article !

    We have created a local repository now. How to keep this repository “current” i.e. in-sync with the latest available packages on the web ?
