There are many reasons you may want a local Red Hat Enterprise Linux repository. Bandwidth is a major factor as downloading updates from the Internet can be time and bandwidth consuming. Another reason may be that your servers are not connected to the Internet and thus need to get their updates from a local source. You may have a development environment that you would prefer to not spend money on licenses for but still need to update. Whatever your reason, this tutorial will walk you through the process of getting your local repository setup.
Note: The server that serves as your repository should only serve as a repository.
First make sure that all other repos have the enabled flag set to 0 (zero) within the repo file in /etc/yum.repos.d. I wouldn't delete the repos for now because you might need them later. Simply changing the enabled flag is enough.
Now you need to create a .repo file that will be added to the /etc/yum.repos.d directory on every server using the repositories. That file should look similar to the following file.

Install packages needed for the repositories
yum install yum-utils createrepo httpd
Create the directories for your repositories
mkdir /var/www/html/rhel6
mkdir /var/www/html/rhel6/server
mkdir /var/www/html/rhel6/dts
mkdir /var/www/html/rhel6/dts2
mkdir /var/www/html/rhel6/rhsc
mkdir /var/www/html/rhel6/server
mkdir /var/www/html/rhel6/dts
mkdir /var/www/html/rhel6/dts2
mkdir /var/www/html/rhel6/rhsc
Helpful Commands
List the repos on your server both enabled and disabled.
yum repolist all
List the repos available on your subscription
subscription-manager repos --list
Enable a repo on your system
subscription-manager repos --enable=rhel-6-server-optional-rpms
Disable a repo on your system
subscription-manager repos --disble=rhel-6-server-optional-rpms
We want to have the server, dts, and rhsc (software collections) repositories enabled on the repositorySync Repos
Once all of these repos have been enabled perform the following command for all of them changing the download_path for each to match the download_path for that repo.
reposync --gpgcheck -l --repoid=repoid --download_path=/var/www/html/rhel6/repo_name --downloadcomps --download-metadata
Note: The server repo will take the longest. Like all night long. The others should be much shorter.
Createrepo Command
Once the packages have been downloaded all that is needed is the createrepo command below for each repo
createrepo -v /var/www/html/rhel6/repo_name/ -g comps.xml
Note: The -g comps.xml is only needed for the server repo.
Setting Up Client Servers
Now you have a local repository but you need to make some changes on your Red Hat servers that will be using these repositories for updates.First make sure that all other repos have the enabled flag set to 0 (zero) within the repo file in /etc/yum.repos.d. I wouldn't delete the repos for now because you might need them later. Simply changing the enabled flag is enough.
Now you need to create a .repo file that will be added to the /etc/yum.repos.d directory on every server using the repositories. That file should look similar to the following file.
vi /etc/yum.repos.d/name_of_repo_file.repo
[server] name = rhel-6-server-rpms baseurl = http://hostname_or_ip_address_of_repository/rhel6/server gpgcheck = 0 enabled = 1 [dts] name = rhel-server-dts-6-rpms baseurl = http://hostname_or_ip_address_of_repository/rhel6/dts gpgcheck = 0 enabled = 1 [dts2] name = rhel-server-dts2-6-rpms baseurl = http://hostname_or_ip_address_of_repository/rhel6/dts2 gpgcheck = 0 enabled = 1 [rhsc] name = rhel-server-dts2-6-rpms baseurl = http://hostname_or_ip_address_of_repository/rhel6/dts2 gpgcheck = 0 enabled = 1
Create Script and Cron Job to Update Your Repositories
Create a script named update-repository.sh and put it in /usr/local/bin with the following contents:
vi /usr/local/bin/update-repository.sh
echo Update script started at $(date) >> /var/log/update-repository.log reposync --gpgcheck -l --repoid=rhel-6-server-rpms --download_path=/var/www/html/rhel6/server --downloadcomps --download-metadata createrepo --update /var/www/html/rhel6/server/ reposync --gpgcheck -l --repoid=rhel-server-dts-6-rpms --download_path=/var/www/html/rhel6/dts --downloadcomps --download-metadata createrepo --update /var/www/html/rhel6/dts/ \\ reposync --gpgcheck -l --repoid=rhel-server-dts2-6-rpms --download_path=/var/www/html/rhel6/dts2 --downloadcomps --download-metadata createrepo --update /var/www/html/rhel6/dts2/ echo Update script ended at $(date) >> /var/log/update-repository.log
chmod 600 /usr/local/bin/update-repository.sh
Note that I have it dropped into a log that I have setup to rotate monthly.
Create a file in /etc/cron.d and name it update-repository with the following content.
vi /etc/cron.d/update-repository
@weekly root /usr/local/bin/update-repository.sh
