CentOS 7 is on its way

CentOS 7 is on its way

Summary: Developers have already started work on CentOS 7, the next version of the popular Red Hat Enterprise Linux clone.


For some companies, the first question after the release of Red Hat Enterprise Linux (RHEL) 7 was: "When will CentOS 7 be out?" The answer is soon.

CentOS, the well-regarded RHEL clone, which recently became a Red Hat partner, is already working on CentOS 7, its RHEL 7 clone. As Karanbir Singh, a CentOS developer, tweeted when asked if CentOS 7 would be out immediately, "Not quite, but we're not far from there either. Just working on getting the ducks all lined up nicely." He continued, "It's going to take a few days to get the RPMs all done, then another few to get ISOs into installable state; we'll post updates."

Singh added, "Looks like we have RHEL-7 released. All CentOS developers ... TO THE BUILDSTATIONS!"

The process, however, for building the next version of CentOS has changed. Jim Perrin, a CentOS project developer, blogged on the official CentOS 7 site, "As part of the preparation for CentOS 7, and with a growing focus around making the source easier to work with for developers and special interest groups, the CentOS Project is publishing the git source tree used for building the distribution. This represents a bit of a change from previous releases and we understand that it will cause some users to change their workflows a bit."

To help programmers get up to speed with this new system, CentOS has put together a wiki page on how to use git with CentOS. Git is a popular version control system that comes with CentOS 6 and higher.

While Perrin isn't ready to give a release date for the new CentOS, he did say that the team is already working on the project and now it's "simply time and testing." As for working with Red Hat, in an email interview Perrin said, "Speaking for myself, joining forces with Red Hat has given me more time to devote to the project. CentOS is my job now, so I don't have to try to contribute after a day job, family time, etc. I get to work on CentOS full time, which is great. I can do more and contribute more, which to me helps things overall."

He added, "Red Hat's also provided us with some hardware. Along those lines, they've also provided us with budget to travel so that we can better put ourselves in front of our users at conferences and other events. That's helped tremendously, both because we now have the time and the ability to actually reach out to the community."

However, CentOS is not simply a division of Red Hat. "We don't really work directly with Red Hat engineering at all," said Perrin. "I'm on a different team within Red Hat, so we're pretty separated from them. From the community side, I feel that we can collaborate with them much more openly than we could in the past. We're able to reach out to the community projects Red Hat has, like oVirt, Gluster, or Ceph, and they're able to interact with us similarly." 

Put it all together and I think we can be certain that we won't see the months of delays we saw with the release of CentOS 6 after RHEL 6 was released in 2010. Instead, I expect CentOS to follow closely on RHEL's heels from here on out. That's good news for the many cloud, datacenter, and web-hosting companies that rely upon CentOS as their day-in, day-out server operating system.

  • News on Scientific Linux as well?

    Scientific Linux is also a widely used Red Hat clone. Is there any news about SL 7?

    It would be interesting to see a feature comparison of CentOS 7 versus SL 7. Whereas CentOS nowadays has the advantage of being part of the Red Hat company, it might be confronted with restrictions that don't apply to SL.

    Regards from a sunny Noord-Brabant, Pjotr.
    • Keen on CentOS 7 but does it give extra value...

      ...compared to LTS distributions like Ubuntu and Linux Mint? And how about when you have to buy new devices including new USB-modems? And Wifi?
  • Redhat is open source, why CentOS?

    Sorry for the ignorant question. Redhad is based on open source technologies. Only support is paid. If so is there any licensing violation if one uses Redhat freely without subscribing to paid support? If it's Ok then what is the reason for CentOS to exist?

    Thanks in advance for your kind guidance.
    • No updates

      Yes u can use redhat free of cost but it won't give you software updates
      • No binary rpm available

        For my understanding when you buy a RedHat subscription you sign a EULA that provide the right to keep installed on a server or VM their binary as long as your subscription is in place.
        When the subscription expires you must deinstall them and, if you want, use packages built from SRPM; It means you need CentOS or SL... because they also take care to remove all trademark files
    • As ankitsagwekar says, no updates, and

      a non-registered Redhat install will not have access to any of the supplemental packages channels.

      Redhat breaks up thier distro into a base repo, and many supplementry repos. Only the base rpms are included on the freely downloadable iso image, and the rest become available as selectable channels once the system is registered.

      CentOS has all the Redhat rpms, and all accessible without registering. Redhat is OK with this, as their focus is enterprise businesses. Enterprise businesses have no problems paying for Redhat subscriptions.

      Redhat is fine with small business using CentOS. The way Redhat looks at it is that once a small business grows to a certain point, the business will decide it needs the assurances Redhat can provide, and will migrate from CentOS to Redhat.

      i.e. Redhat sees CentOS as nursery for Redhat customers.

      I think its a very sensible business plan on Redhat's part.
      • Make all sense


        Thank you very much for the clarification.
  • Is it possible to put all RPMs on a single USB drive?

    USB drives has been out in the market for many years. Yet we still see RHEL distributed in 2 DVD disks. While CENTOS is at it, is it possible to put all RPMs in a single USB drive and install from this single USB drive?
    • Both Redhat 7 and CentOS7 DVD images can be put on a USB device

      You can write the the DVD .iso image to a USB device and then boot from the USB device to install. I use 'dd' on Linux for putting the iso image onto the USB device, but there are many utilities for Win/Mac/Linux to do this.

      As to having 'all' the rpms on a USB stick: Most of us don't worry about having 'all' rpms on our install media. Since updates come out regularly, it is a lot of work attempting to keep any install media up to date.

      The simpler way is to just install a base system from USB or DVD media, then update the install and add to it using Software manager under X-Windows. This way, the install is quick, and a after an update (step 2 of any OS install), you can easily add the newest versions of whatever you want directly from Internet repos.
      • All RPMs in the 2 DVDs in a single USB drive.

        Thank you. Sorry wasn't clear on my question. I meant all the RPMs on the 2 DVDs into a single USB drive. I am a novice playing around with LINUX hoping to use kickstart with minimum interaction.
      • It's much better to use USB device when installing Linux distribution...

        ... because it's much faster and seems to eliminate lots of other troubles. I haven't use DVD or CD for install since 2010.
