CentOS 6
50 Replies
It was supposed to rsync to mirrors on July 5th. It's now the 9th and not a single mirror has it, nor has the dev list announced it's actually released.
Linode should switch over to Scientific Linux. Less Drama, more timely releases.
SL6 doesn't do as rigorous testing as CentOS; some broken dependencies were in their release. SL6 is not a replacement for CentOS.
@sweh:

What's the source on that statement?
We've moved from CentOS 5.5 to SL6.0 with zero problems (so far - knock on wood), but if there's something published about SL please share.
//and I still can't find a mirror with CentOS 6.0
C6 is internal sync'ing on the mirror network; not yet open to the public. But it is sync'ing, as they said it would. According to qaweb (
You'll probably be able to tell when it goes live:
> Update: 4:10PM PDT – Mirrors are picking up the release. The mirrors will remain "bit-flipped" (read: locked from public access) until it's decided that the release has made it to a sufficient number of mirrors for release. Watch the CentOS-Announce mailing list and/or #centos IRC channel for more info on the release. Anything you download from mirrors before the announcement may not be the final packages, and you may put your system into a funky state -- use at your own risk.
Huzzah!
regarding 6.1
> Since upstream has a 6.1 version already released, we will be using a
Continous Release repository for 6.0 to bring all 6.1 and post 6.1
security updates to all 6.0 users, till such time as CentOS-6.1 is
released itself. There will be more details about this posted within the
next 48 hours.
So, install away is my vote!
@bleeter:
+1 for C6
me too!!!
1) MySQL enabled Postfix (instead of just LDAP)!
2) Sieve plugin for Dovecot!
I'd be a pretty happy guy if this appeared…
@sblantipodi:
can't wait to install it on my linode.
Have you done it through the recovery console yet? If so please send directions my way
I created two partitions, one for /boot, and one for /. From here, I booted into finnix and dropped the kernel and initrd into /boot/install (just a directory I made, nothing fancy – I just didn't want any conflicts). A simple reboot into pv_grub, and type three lines:
root (hd0)
kernel /install/vmlinuz
initrd /install/initrd.img
… and it will kick off the installer. I'll give you a warning though: it isn't going to be pretty over lish.
If you have the RAM, you can pull off a GUI install over VNC, and specify a password on the kernel boot line. See this for all of the options:
PS: Pull the vmlinuz and the initrd.img file from almost any mirror… such as this one:
edit: so there are issues with the lish console and the installer, namely the disk selection part. So, I wrote a kickstart file. This will install almost nothing -- a grand total of 208 packages -- and if you know what you're doing with respect to partitioning and etc, you can probably have a C6 install up and running in 10 minutes.
You'll probably have to play with the partition options

Thanks man, I'm a newbie when it comes to some of this, but I was able to get it installed using the method you mentioned.

On the upside, I've got selinux now…
> Linode has PV-GRUB configured to search for menu.lst at (hd0)/boot/grub/menu.lst. This means that your first disk (ie. /dev/xvda) cannot be partitioned. It has to contain a filesystem with at least your /boot directory (including /boot/grub).
So you'll need to perform surgery on xvda to remove the partitioning and replace it with just a straight filesystem. tar it up, mkfs.ext2 (or 3) /dev/xvda, and then extract it again.
Once extracted, you'll need to put one more symlink in place to appease the linode bootloader, but that is a simple ln -s . boot once you're in /boot.
Be sure to update your /etc/fstab with the new UUID (find it in /dev/disk/by-uuid) and potentially your /boot/grub/menu.list as well to point to the proper device (mine only said 'xvdb1' when it should have said 'xvdb1').
So yeah, that kickstart is not exactly optimal. :)
hoping that it will arrive soon.
It now boots and I am on my way.
Thanks for your help!
@sblantipodi:
personally I will wait for an official support from Linode guys,
hoping that it will arrive soon.
@dffdce:
CentOS 6 (32 and 64 bit) is now listed in the Distribution drop down!
its true, is it stable and officially supported now?
I will wait for an official annoucement.
@vonskippy:
As it's listed under their "Current Distro" on their FAQ page, and it's a choice in their which distro pull down menu, I'm not sure it can get any more official.
ok, is there some saint that will make a small guide on how to painlessy switch from CentOS 5.6 to CentOS 6?
Looks like no…
@kbrantley:
http://bugs.centos.org/view.php?id=4946 Looks like no…
I don't mean to upgrade centos 5.6 to 6.0, I mean that it would be great to have a guide on how to install centOS 6.0 on new linode and than transfer the configuration from the old one to the new one.
Heare, heare, let all members of the land of Linodeia know that from this date forward the vast greatness of CentOS 6.0 will be available to all good citizens. Use it in good health so that all in the Kingdom may prosper!

There, are you happy now?

its funny but they usually makes a news for every new distro available on linode.
This is comfortable because I know when a new distro is available from my RSS client without needing to visit the forum every day and without needing to login to my llinode's dashboard every time I want to know if a distro has been supported.
Can't understand why they doesn't made a news for CentOS

Yes please, for a real novice like me this would be immensely helpful, because it was already hard enough setting the server up in the first place.
@obs:
There is no upgrade path between 5.6 and 6.0 you have to build a new server and copy your files over.
I have just done the upgrade, this is true.
@sondrizzle:
Yeah, but I was wondering more about how you copied the files from server to server and such…
I have a partition where I store my services and my website file,
that partition can be copied painless by using the clone funtionalities from linode manager.
The configuration file must be copied manually or using ssh GET or SCP if you need to transfer directory.
With SCP I transferred directories at lighting fast speed from my linode to my second linode because the two nodes are on the same datacenter.
You know, there are many ways to transfer files between servers.
Software must be obviously reinstalled from scratch but yum + epel is your friend.
Pay much attention to the mirror priorities, epel is really unkind with other repos.
