  2. Roman Gherta says:

    Matei in Centos we were receiving this error.

    “User cannot register with any organizations”
    until we executed
    subscription-manager register –username your_username –password your_password –auto-attach

      It seems you don’t have a RedHat subscription, means you can’t register your system to RedHat network repository.

      • Roman Gherta says:

        I actually had a username registered but still got that error. It wasn’t until I used the –auto-attach parameter that it worked as expected.

        • Ravi Saive says:


          I didn’t noticed that –auto-attach parameter in the command you posted, anyways thats great it worked for you finally..:)

  5. Nic says:

    There is an error in the code for listing all the services

    you have “-available” but in the print screen you have “–available”

    Please look into resolving that – Cheers.

    Great blog otherwise.

    do you have to register the core edition of centos 7? I used the minimal installation disk from the online centos source page. it does not a redhat any where in the boot up. is that still consider redhat to..

    • Ravi Saive says:


      Only RedHat distributions needs to be registered to RedHat subscription to get package updates, CentOS distributions is free and doesn’t required any registration to get package updates..

  7. dilshath says:

    For this subscription, Redhat will deduct the amount?

    • Ravi Saive says:


      Yes, they have yearly RedHat subscription plans, you need check out official RedHat subscription page to know more about it..

    Hi Matei nice tutorial, l have redhat 7.2 and l need repos for rhscl for installing php55, but seems not to find them, can you help me how to get those repository ?

  9. Matei Cezar says:

    Simple as that, no! The packages will remain installed on your system forever and ever, unless you manually choose to uninstall them! Feel free to upgrade the system, but after that month support, you wont be able to upgrade packages anymore!

  10. Rinshad says:

    Hi Matei,

    Thank you for the detailed post. If I subscribe 30 Day Self-Supported RHEL free subscription, can I upgrade my system to latest version? and what will happen after one month? all the packages that I have installed in system will lost?
