Is there something notable about this beyond just a new version?
- geerlingguy 12y ago
  RHEL 7 was released on June 10[1], but many people (myself included) don't have a RedHat subscription and run CentOS, the 'community' edition of RedHat. Up until today, CentOS 6.5 was the latest release... so I can start using CentOS 7 now and enjoy the benefits that RedHat introduced in RHEL 7. You can see that the delay before CentOS releases a community version of RHEL has been much improved in recent years in this Wikipedia chart[2]. Also, iirc, this is the first major CentOS release with the CentOS project more or less under RedHat's wing[3].

  CentOS/RHEL 7 uses systemd. That's a notable change. Also, LXC and docker should work out of the box. And xfs now instead of ext4 by default. Release notes: http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7

You can go to https://git.centos.org https://git.centos.org which is hosting all the sources used to build the system. Of course for RPM packages that is only metadata, not the actual upstream software source.
- justin66 12y ago
  Just out of curiosity, since it sounds like you might know: on ubuntu I can do something like sudo apt-get source packagename and the system will just download the associated source code if a source repo is setup in the system's sources list. Does RHEL/CentOS have a similar capability?
  - priteau 12y ago
    Yes it does. "yumdownloader --source package_name" will download the source RPM. yumdownloader is part of the yum-utils package.

Woo. Have been using the RHEL 7 Amazon AMI images, and it's nice not to worry about shell scripts / custom supervisord stuff for your web services anymore. My node app is deployed with a single `myapp.service` file thanks to systemd: [Service] ExecStart=/usr/local/bin/node --harmony /var/www/myapp/server.js Restart=always User=nobody Group=nobody Environment=PATH=/usr/bin:/usr/local/bin Environment=NODE_ENV=production [Install] WantedBy=multi-user.target Then: iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000 (since I run my app on a low port so it can run as nobody, and 3000 isn't visible to the outside) cp myapp.service /etc/systemd/system systemctl enable myapp.service systemctl start myapp.service This has all the stuff you expect: - Not restarting repeatedly if the app is bouncing up and down. - I can see how it goes with `journalctl` which reads journald messages, and those messages come from a source called `myapp` rather than the old ancient syslog facilities (local0, uucp, lpd) which everyone just ignored in favour of grepping.
- netcraft 12y ago
  that looks so much cleaner than init.d scripts. I have heard some people refer to systemd as not very linux-esque - can someone comment on what that might mean?

      It looks like the listed minimum for RHEL 6 was 1gb[1].

  CentOS is a repackaged RHEL, with all the Red hat IP (logo's, artwork etc.) stuff stripped out. So it's almost the same distribution. As such, the only advantage RHEL probably offers next to support are slightly faster updates.
  - jerven 12y ago
    And actually being able to call redhat can be very useful once in while when you are having a really bad day.
    - TallGuyShort 12y ago
      Given that the OP said "other than support", I'll assume you mean they're actually nice and supportive when call to complain about your day :)

        Thanks! I somehow completely read over that part :) But my my single experience with RedHat support was a real pleasure.
- derekp7 12y ago
  The support goes both directions. It is a way to get the organization you work for to indirectly donate to a variety of free software projects, and your company also gets the contractual safety net that they want.

I always scare of CentOS/Fedora. Whenever I updated something, it will be very old packages. Leading to use 3rd repo, and without any kind of document, the next sysadmin will be in trouble. I used to install Gearman on Centos 5.9 and it was a nightmare: the original 3rd repo didn't have gearman and I have to use other repo which is complain about PHP-Common conflicting. Remi and webtactic did help at the end. It's hard to keep Centos Update to date with latest software IMHO. I'm not an SysAdmin but I think the idea of APT and YUM is same but why it's so hard/trouble to use YUM?
- TallGuyShort 12y ago
  Perhaps it's what you're familiar with and the intended use case. I personally can't stand the way APT won't let you override certain behavior. RHEL / CentOS have always favored stability over being bleeding-edge, and in my experience EPEL provides enough newer software to make the system usable for most cases, although if you're wanting the latest frameworks, etc.. I can see that being incompatible with your needs. I have very rarely had any problems with broken dependencies in Red Hat repositories except for the occasional 15-minute hiccup. SUSE seems to have more problems, but still has never been enough of a problem to make me question using it in production.
  - derekp7 12y ago
    I think the third-party frameworks issue can be solved with LXC / Docker. If app x requires library y and supporting utility z, this can all be put into a container without having to update the OS's versions of y and z.
    - TallGuyShort 12y ago
      Although personally I've had more instances of running into an incompatibility with the older CentOS 5 kernel than with any of the libraries in the distribution - which LXC wouldn't be able to help with.
- jamescun 12y ago
  Fedora is the RedHat "testbed" and has regular updates similar to the debian/ubuntu universes. One of the core features of CentOS/RedHat/Scientific Linux/etc is their longterm support and package freeze (excluding critical security updates). If you are reliant on a different version of software from the default repositories (both newer or older) then you are encouraged to build and package them yourself. Additionally in the RedHat-derivative universe there is the EPEL package repository which contains a wider range of software and is kept more readily updated in addition to being maintained by the Fedora Project (essentially RedHat).
ck2 12y ago
I can learn to adjust to systemd But wow I cannot stand grub2, what a mess.
- rando289 12y ago
  Agreed. Config files 100 times bigger and more complicated. Why? Go to it's home page and find a link that says "differences between GRUB Legacy and GRUB" which simply goes to the grub .97 manual which says absolutely nothing about differences between the 2 versions. They really care about their users, that's for sure.
  - mercurial 12y ago
    On Debian you usually stick to changing options in /etc/default/grub and don't touch anything in /etc/grub.d.
- scurvy 12y ago
  Aye, and now grub2 requires a 1MB partition to boot a GPT labelled disk on a BIOS (non-EFI) system. Well, looks like we're out of primary partitions. Adios swap.
  - tacticus 12y ago
    GPT labelled disks don't have a limit on the number of primary partitions
    - scurvy 12y ago
      Nice! Didn't know that.
- reality_czech 12y ago
  grub2 is pretty much the textbook definition of "overdesigned." All it has to do is transfer control to the OS... that's it. But somehow it grew code to parse filesystems, set up graphical user interfaces, load modules, and do half a dozen things that it really has no reason to do. Half the time this hairball won't even boot after you change something, because you forgot to run the correct script to refresh the other scripts, or you moved something on the disk. Just install elilo and enjoy having a system that actually works.

- ck2 12y ago
  Thank you for this! I was going crazy trying to figure out how to get "eth0" back. Works perfect. yum install net-tools is also a must I think I've spent the first dozen hours with centos 7.0 just trying to get it to behave more like 6.5 Having to remember to run a script every time I edit grub configuration is annoying as hell too. grub2-mkconfig -o /boot/grub2/grub.cfg I mean that is so natural and easy to remember, lol - I had to make "update-grub" (like debian) an alias for it

Now there are 2 kernel boot parameters required to get old style "eth#" interface names. net.ifnames=0 and biosdevname=0 CentOS 6 only required biosdevname=0

Thank you for this! I was going crazy trying to figure out how to get "eth0" back. Works perfect. yum install net-tools is also a must I think I've spent the first dozen hours with centos 7.0 just trying to get it to behave more like 6.5 Having to remember to run a script every time I edit grub configuration is annoying as hell too. grub2-mkconfig -o /boot/grub2/grub.cfg I mean that is so natural and easy to remember, lol - I had to make "update-grub" (like debian) an alias for it

Will I still be able to run commands like service mysqld start, etc?
