How do I create a RHEL or Bright repository for my organization?

In ceratin cases, the Bright cluster is not able to access the internet directly or having a local repository withing the companies intranet is beneficial e.g. in the case were a site is hosting multiple clusters. This KB article will describe how to create a local repository using the Bright headnode's webserver. The same instructions can be used also in the case that the local repository needs to be created on a non-Bright headnode provided that it has YUM installed and that the remote repositories are configured properly or the RPMs can be obtained from a DVD or ISO image.


cd /var/www/html

mkdir repos

cd repos


There are several ways to add RPMs. You can either copy them directly from a Bright ISO or DVD:


mount -o loop <ISO image> /mnt/iso


cp -r /mnt/iso/path/to/rpm/rectory /var/www/html/repos


or use reposync, a utility that will create a local copy of an online YUm repository. 


To install reposync:


# yum install yum-utils


Provided that the YUM repositories are properly configured on the headnode (see the output of the 'yum repolist' command), the following script can be used:



## declare an array variable
declare -a arr=("rhel-6-server-rpms" "rhel-6-server-optional-rpms" "rhel-server-dts2-6-rpms", "cm-rhel6-7.0", "cm-rhel6-7.0-updates")

## now loop through the above array
for i in "${arr[@]}"
cd /var/www/html/repos
mkdir -p $i
reposync --gpgcheck -l --repoid=$i -n
cd /home/rhel/$i
createrepo -v /var/www/html/repos/$i


The -n flag at the end of the reposync command instructs reposync to download only the latest version of each RPM that is available on the remote repository. You can add ore remove repositories from the array variable as needed.


To use the newly created local YUM repository create a .repo configuration file in /etc/yum.repos.d for the headnodes and /cm/shared/<software image>/etc/yum.repos.d for the software images.


[root@kerndev ~]# cat local-yum-repo.repo
name=My Red Hat Enterprise Linux $releasever - $basearch
baseurl=http://<hostname of webserver>/repos/rhel-6-server-rpms

name=My Red Hat Enterprise Linux $releasever - $basearch
baseurl=http://<hostname of webserver>/rhel-6-server-optional-rpms



If the repositories need to reside outside outside /var/www/html becuase e.g. the /var partition is too small then create an allias directory in the webserver's configuration:


vim /etc/httpd/conf.d/local-repo.conf


Alias /repos /home/repos

<Directory /home/repos>
Options Indexes MultiViews FollowSymLinks
Order allow,deny
Allow from all
and restart the webserver:
# service httpd restart
