Looks like a release candidate. > At this point we have a set of images that we consider release grade, pending final testing, we will move to release these unless a major blocker is reported.

  the site is not loading what's new besides upgrades?

    That page was just a list of links to download the images for testing.

looking forward to trying systemd, hope it isn't too much of a learning curve. Looking at: http://tecadmin.net/red-hat-enterprise-linux-7/# http://tecadmin.net/red-hat-enterprise-linux-7/# - will HAProxy come with centos 7?
- msumpter 12y ago
  Anything that is in the standard release of RHEL7 will be in CentOS7. But for sanity sake I checked one of the 7 mirrors and there is an HAproxy (1.5) RPM: http://mirrors.easynews.com/linux/centos/7/os/x86_64/Packages/haproxy-1.5-0.3.dev22.el7.x86_64.rpm http://mirrors.easynews.com/linux/centos/7/os/x86_64/Package...

  It honestly isn't. The documentation is really good if you know how to use google.
  - pling 12y ago
    Until its your network gatewayb appliance that is down and then you're fucked... NEVER rely on Google for documentation or GNU info as that's probably not installed on your server. This sort of scenario is where *BSD win every time.
    - SEJeff 12y ago
      The man pages are also available for every systemd app.
      - pling 12y ago
        Ok my bad there. Last time I looked there were no manpages.

  It's quite sad, in my opinion, that this is halfway down the page while yet another beating of the dead horse that is the systemd flam^H^H^H^H discussion is the most visible comment thread. Thank you for posting this.

Even this article title says "POTENTIAL" release. I am not even sure it is signed? They are still doing QA, it will be a week or two before GA Before you rush to 7.0 after 6.5 - things you are going to have to learn because they change everything: systemd replaces init.d grub2 replaces grub xfs is now default over ext4 filesystem (many, many people dislike systemd, it is somewhat anti-linux in nature) No more easy editing/understanding grub.conf No more easy to edit/understand /etc/init.d (systemctl instead) No more text log files for system log (journalctl instead) Watch out for default XFS filesystem instead of EXT4 because it is slower in real world use for databases, etc. Red Hat claims RHEL7 is 11-25% faster than RHEL6, I am not convinced at all, I think they are referencing a stock setup for 6 vs 7, but I don't know anyone that runs things stock without tuning. Wait for independent benchmarks. CentOS 6.x will be supported until 2020 If you want a 3.x kernel for CentOS 6.x, try the ELrepo repository, they do builds for both mainline and longterm 3.x kernel releases. http://elrepo.org/tiki/kernel-lt http://elrepo.org/tiki/kernel-lt If you want newest GCC for CentOS 6.x try the CERN repo for devtoolset http://linux.web.cern.ch/linux/devtoolset/ http://linux.web.cern.ch/linux/devtoolset/ ps. there is currently no way to upgrade a 6.x install "in place" to 7.x, though Red Hat has migration tool and CentOS folks say they will look at doing the same - but like I said, don't be in a rush to early adopt 7.x pps. RHEL7 notes are a way to explore what else is new: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/ https://access.redhat.com/documentation/en-US/Red_Hat_Enterp...

  Thanks for posting this. That's what i was expecting. Does any of that really improve my day? Nope. In fact most of it makes it worse and adds friction. More cogs turning in different directions. Will keep our devops stuff on CentOS 6.5 for at least another 4 years...

A few mirrors already have the full version, so if the site is offline, you can - for instance - grab one from a Belgian hoster; http://centos.mirror.nucleus.be/7/ http://centos.mirror.nucleus.be/7/

If I were a large enterprise I'd reconsider CentOS. RedHat's lack of a commitment to the customer's experience in favor of RH's personal design preferences smacks of Oracle-ism. Anything they develop they immediately force on their users, and you have to just accept it rather than use it optionally. It's less easy to get away from those kind of changes versus something more open like ubuntu/debian (and I have no love for debian). And then there's the whole secret kernel patches and backported "features"... Then again i'm a dirty hippie who prefers Slackware, so maybe i'm too Linux-libertarian for today's enterprises.
- SEJeff 12y ago
  Care to elaborate? Systemd has a few nice features that I (as a systems admin of thousands of servers) really like such as: - simple "init script" like upstart, so magical or crappy shell scripts from vendors are a thing of the past. A standardized unit file - Ulimit support natively as part of the format - Limiting via memory/disk/cpu cgroups to contain buggy apps (hello mysql!) - Process restarting so tools like supervisord, monit, runit, etc are no longer necessary - It can _always_ stop an errant daemon as it uses control groups to do so, sysv init was sometimes buggy in this regard - Private /tmp (via filesystem namespaces), limiting system calls a service can run, tcp wrappers, read only parts of the filesystem (like /etc) are all trivial to add to any legacy service such as bind or sendmail and a supported part of the systemd unit file definition. RHEL/CentOS 7 also include some super nice things like the new abrtd for centrally reporting any application coredump/kernel issue, pacemaker/crm for high availability clusters, and just a lot newer linux userspace. (yay for du -hsc | sort -h | tail) As an _actual_ user who uses RHEL/Debian/etc on bare metal at scale, I really see nothing but awesome in RHEL7. It is just like I see awesome in Fedora 20 or in the latest Ubuntu/Debian. The Linux ecosystem has massively grown. Now we have a serious engineering company putting a lot of resources into supporting a new operating system. I'd love to see some of the technical reasons you have the opinion you do.

    I'm not going to turn this thread into a debate over the merits of individual contributions to CentOS. All i'm saying is whatever RH develops gets shoved into their distro with seemingly no regard to the customer. It's not just that they're adding new tools, they're also forcing you to use them. The nice thing to do for your customers is to make new technology optional, and provide alternatives for people who have 10+ year old infrastructure that they don't want to spend 2 years upgrading because it's now full of legacy systems. But RH not only shoves anything they want down your throat, half the time they're not transparent about the changes taking place, and you just have to hope nothing breaks your apps (kernel as an example, but userland package changes are similar).
