    Hi Sir,

    How to downgrade to the previous O/S version, suppose i want to downgrade from Centos6.7 to Centos 6.4 release. Please help

    • Ravi Saive says:

      Unfortunately, you can’t rollback whole CentOS version, but you can downgrade or rollback a specific version of package in CentOS using following command.

      # yum downgrade packname

    Can you show me how to update it if my server is offline?
    My server is CentOS release 6.4 (Final) and I dont have other linux servers available.

    Can I somehow download the updates manually in a windows workstation, use Winscp to transfer them to the Linux server and install them locally through Putty.

    • Ravi Saive says:

      No way and not possible to update offline, the only way is to update online, because the updates are fetched from official CentOS repository and we don’t which package and how many packages needs to be downloads and installed during updates..

  3. Hi ,

    I am using CentOS 5.8 From many days on my Database server, its working perfectly fine, now i bought Dell R630 server, these are new generation server’s so Dell R630 is not supported for 5.* series. And CentOS 6.4 is also showing me Error like “This Hardware is not supported by CentOS” .
    so i want to ask you, can i go with 6.5 or 6.6, both are able to install and also there is no ant error while installing.
    But which is more stable and bug free version. which should i use for my server CentOS 6.5 OR CentIOS 6.6.

    Please suggest me .

      All CentOS 6.x versions are stable and bug free and better in performance, you should go for CentOS 6.5 as this is the one of the best stable version I worked with..

    Is this the same procedure, if upgrading from CentOS 5.x to 6.5 ?

    • Ravi Saive says:

      No you can’t jump directly from CentOS 5.x to 6.x, you need to do a fresh installation of CentOS 6, this is the only way..

      • Pavan says:

        Thanks a lot. True, It upgraded from 5.6 to 5.10 when i tried. So will go ahead and do fresh installation.

    I’ve seen several web sites with this basic instructions, but I have a less than ideal configuration. Due to very strict firewall rules, our servers can not go out to Internet yum repositories and we have to use an in house mirror.
    One consequence of that is our repo.conf files use fixed paths in the base url’s rather than the dynamically generated paths to mirror repositories for the Internet mirrors.

    I’m sure there is a stage in the yum update where these paths change from http://mirrror…/6.3/.. to http://mirror/…/6.4/… in the normal configuration, but I’m going to have to do that manually. At what point in the upgrade does the yum switch repositories?

    • Ravi Saive says:

      Yes, you correct yum switch to other mirrors, if current mirrors fails to fetch data or you can define custome repos like yum –enablerepo=reponame install package name..

    Hello Ravi, I came upon your post after I went to build some new machines and found I could no longer download ISO’s for CentOS 6.1-6.4. It seem’s as if they were blown away in most if not all mirrors.

    Was there a major flaw/vulnerability in the previous releases?

    I have not found much related to why the change was so quick and destructive. It makes me wonder.. Was there a vulnerability so extreme or perhaps NSA tampering?!?! Haha. Apparently, I am tardy to the party.
