Howto get Red Hat Enterprise Linux Installation Number

Posted on in Categories , last updated April 10, 2007

Q. While installing Red Hat Enterprise Linux it asks Installation Number. Where do I get red hat enterprise Linux installation number?

A. Red hat Enterprise Linux is a commercial subscription based product. During installation you need to supply a 16-character long string or serial number. Without this number you will not able to install:

=> Packages

=> Updates

=> Security patch

=> Additional applications

=> Support etc

If you are looking for free Linux version, try any one of the following for Server Installation:
=> CentOS

=> Debian Linux

  2. Hi All

    We have 1 Subscription for Red Hat Linux Enterprise edition. This will be used as a server, we need similar kind of setup for 10 number of clients machines which will be used for testing.

    Is it necessary to go for additional 10 subscriptions or shall i use the same installation media. Any way I don’t want any kind of support for client machines.

    If I configure, as described above is this going to be an illegal way of using subscription.

    Is there any Red Hat document which describes as per my requirements?
    Please help me on this query.

    Thanks in Advance

  6. Hello Folks,

    I had downloaded RHEL 5.3 .iso images from redhat network couple of days back & was searching for installation/subscription #s for adding cluster & virtualization suite to my RHEL instance.

    I’ve done the server core installation skipping the installation/subscription # screen but now want to add the cluster & virtualization suite. Could anyone among you share the installation #s for these?

    [Rekhu Prasad]: The installation # you had shared i.e. “22eda90c23f9e5a9”, using this will I be able to add cluster & virtualization or this would just register me to RHN for system updates?

    Guys, also kindly let me know whats the procedure for adding these optional suites after I’m done with the core installation? Do I need to mount the .iso image & just run the required .rpm or is there any option from desktop menu?

    I have an existing version of a LINUX ISO ver. 5, which I am trying to install on a Virtual machine.When I skip the installation number it gets installed very well(I am using it), however , when I try to install the Server by adding the server license it stops at the point installing the Apache.I have tried the SMB and the client however the keys ar not working.

    Second Query:
    I am also looking for a recent version of RED HAT which I can purchase. Can anyone suggest, which is the Latest version of RH Linux? Is it RHEL 7, 9 or 10?
    Is the 30 day version downloadable?
