I'm in the process of purchasing a RHEL license. In the meantime, I'd like to utilize CentOS 7 repos on my RHEL 7. I created a /etc/yum.repos.d/centos.repo file in the /etc/yum.repos.d directory but I don't know how to move past that. Most of the information I found online either points to fedora repos or is referring to CentOS 5. Below is something I found online and copy pasted onto my centos.repo file. Thank you.

[centos]

name=CentOS $releasever - $basearch

baseurl=http://ftp.heanet.ie/pub/centos/7/os/$basearch/

enabled=1

gpgcheck=0



[base]

[contrib]

Delete this centos.repo (or change enabled=0 for all) and Create a new repository centos1.repo in /etc/yum.repos.d/ with the content:

[centos]

name=CentOS-7

baseurl=http://ftp.heanet.ie/pub/centos/7/os/x86_64/

enabled=1

gpgcheck=1

gpgkey=http://ftp.heanet.ie/pub/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7

Then run

yum repolist

Now check if you can install any package like

yum install nmap -y

Done!!!

You can use repo-file from CentOS, but need to prepare it:

1. 
   

   Replace $releasever inside this file with the appropriate release number (e.g. 7 for RHEL-7):

   
   
   

   sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo
   
   

   
   


2. 
   

   Download key:

   
   
   

   curl http://ftp.heanet.ie/pub/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7 >/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
   
   

   
   
   

   or change inside repo-file gpgkey's to url, as in @erTugRul answer:

   
   
   

   gpgkey=http://ftp.heanet.ie/pub/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7
