If you are supporting Oracle Linux, the official repos are here: http://public-yum.oracle.com/

You can create a custom repository to serve up your own RPMs or a mirrored copy of a repo.

1. Install Apache Web Server and Create Repo packages

   yum install httpd createrepo

2. Start and enable the web server
   1. EL 6

      service httpd start
      chkconfig httpd on

   2. EL 7

      systemctl start httpd
      systemctl enable httpd

3. Create the directory structure

   mkdir -p /var/www/html/repos/mycustom

4. Copy your RPMs to the directory

   rsync -avhP *.rpm /var/www/html/repos/mycustom/

5. Create the repo data

   createrepo -v /var/www/html/repos/mycustom

   1. For future package updates/additions, run the createrepo command with the “–update” option in order to only update metadata for packages that have changed

      createrepo -v --update /var/www/html/repos/mycustom

On clients that will use the repo:

1. Create a repo file

   vim /etc/yum.repos.d/mycustomrepo.repo
    
   [mycustomrepo]
   name=My Custom Repo
   baseurl=http://server2.example.com/repos/mycustom
   gpgcheck=0
   enabled=1

2. Cleanup yum

   yum clean all

3. List repos

   yum repolist

4. Install a package from the repo to test

   yum install <package-name>
