Configure yum to install dependencies automatically

I just install RHEL version 6.4. trying to use yum command to install rpm-build package, but it showing below error messages: [root@redhat64 ~]# yum install rpm-build Loaded plugins: product-id, security, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Setting up Install Process No package rpm-build available. Error: Nothing to do By default, if you check with “yum repolist all” command, there are 2 repo source with status disabled:     [root@redhat64 ~]# yum repolist all     Loaded plugins: product-id, security, subscription-manager     This system is not registered to Red Hat Subscription Management.

The easy way is build a local repository from your current redhat’s DVD / ISO file:     # mkdir /media     # mount /dev/cdrom /media Rename existing repo file “rhel-source.repo” to “rhel-source.repo.backup” or whatever you want.

Create another repo file name, example “dvd.repo”: 

(Note: keep in mind that never use the default repo name, such as "redhat.repo", otherwise the repo file will be emptied automatically once perform "yum repolist")
