| Kolan | Hi, Im about to setup a Dual Xenon EM64t server serving Apache/PHP/PostgreSQL on 4GB Ram. should I choose the AMD64 version of ubuntu? | 03:05 |
| Kolan | or would it be the same to use the regular? | 03:06 |
| === _JulienH_ [n=JulienH@tru75-2-82-67-204-235.fbx.proxad.net] has joined #ubuntu-server | ||
| infinity | Kolan: Yes, you want the amd64 version. | 03:12 |
| Kolan | infinity: thanks for the response, I was looking on the server wiki which is linking and talking about that Drapper is the build to use. Should I be safe to install that even though its not a stable release? | 03:15 |
| infinity | Safe? I suppose. But it's not released and not supported. | 03:16 |
| infinity | Where does it say to use dapper in production? | 03:16 |
| Kolan | its not saying anything about to use it in production | 03:16 |
| Kolan | but it describes it as it was a production release.. would you recommend me to install Breezy? | 03:18 |
| infinity | Well, if you want stability in production, you want breezy. | 03:18 |
| Kolan | as this server is to be in production | 03:18 |
| Kolan | ok | 03:18 |
| infinity | If you don't mind upgrading occasionally for the next couple of months and helping us find and fix bugs, dapper's cool. | 03:19 |
| infinity | I certainly don't mind people testing dapper and filing bugs for me to fix, just as long as you're aware that it's an unstable release, and you don't scream to loudly if we occasionally goof it up. | 03:19 |
| infinity | If it's a production box, please install breezy. :) | 03:19 |
| infinity | And after you install it, you'll want to install "linux-amd64-xeon" to get the Xeon-tuned kernel for your CPUs. | 03:20 |
| Kolan | ok.. is that even though I install the AMD64 version? | 03:23 |
| infinity | Yes, the amd64 installer will install "linux-amd64-generic" which is a very generic amd64 kernel that runs okay on Athlon64, Opteron, and Xeon systems. | 03:24 |
| infinity | The tuned kernels (-k8, -xeon, etc) run better on their target platforms. | 03:24 |
| infinity | This is no different from the i386 install, which installs a -386 kernel by default, but you may want -686, -k7, etc. | 03:25 |
| Kolan | okay.. is there any special kernel for smp aswell? | 03:25 |
| infinity | The xeon kernel is SMP-enabled. | 03:26 |
| Kolan | ok | 03:26 |
| infinity | (based on the argument that none of us have ever seen a useful Xeon system that wasn't SMP) | 03:26 |
| Kolan | I've been struggeling to get Debian up an running on this server for a week, but as their kernels are to old it dosn't work with the configuration I've | 03:27 |
| infinity | breezy should be okay... | 03:27 |
| Kolan | ok :) we'll see | 03:28 |
| infinity | If the system really does have a lot of incredibly shiny new hardware, you may be stuck having to try a dapper install CD. | 03:28 |
| Kolan | mm.. it shouldn't, it runs well on xBSD | 03:28 |
| infinity | Hey, the BSDs beat us to new hardware support sometimes. :) | 03:29 |
| infinity | (Though, not often) | 03:29 |
| Kolan | well according to the company that deliverd the server it has runned on FreeBSD for almost 1.5 years | 03:30 |
| Kolan | with this hardware | 03:30 |
| infinity | Oh, then yeah, it's crusty, old, and will happily run Ubuntu. :) | 03:32 |
| infinity | Probably even Warty or Hoary, if you feel like going back in time. | 03:32 |
| infinity | (warty not recommended, we just dropped support for it) | 03:32 |
| Kolan | I'm burning out the Breezy AMD64 CD right now | 03:36 |
| Kolan | so no worries about older version are needed | 03:37 |
| Kolan | what about when the Drapper's going stable, is it possible to upgrade than? how is that working..? | 03:38 |
| infinity | Dapper, not Drapper. :) | 03:38 |
| Kolan | sorry | 03:38 |
| infinity | And yes, dist-upgrading between releases is generally painless. | 03:38 |
| Kolan | ahhh... Ubuntu seems to be a dream :) | 03:39 |

| Kolan | how big should the SWAP partition be if I've 4GB of Ram | 03:55 |
| infinity | As big as you like. | 03:55 |
| Kolan | so theres no general rule about 2xRam-size | 03:56 |
| infinity | If it's not going to be a massively loaded machine, it may never swap anyway, but if you have plenty of disk, it doesn't hurt to have swap. | 03:56 |
| Kolan | ok | 03:56 |
| infinity | I usually do RAM*1.5, but that's just force of habit, no hard rule. | 03:56 |
| Kolan | ok | 03:56 |
| Kolan | I've also been recommended to use JFS as filesystem on /var since databases works better on those. is this something known? I've never heard about it before | 03:58 |
| infinity | I wouldn't recommend it, personally. | 04:00 |

| Kolan | any special arguments for that? | 04:02 |
| infinity | Stability, peace of mind. | 04:03 |
| infinity | The two most stable filesystems on Linux currently are ext3 and xfs. | 04:03 |
| infinity | I generally use the former, unless I have a wonderfully good reason to use the latter. | 04:03 |
| infinity | (because the latter still has a few really weird corner-case bugs that confuse people sometimes) | 04:03 |
| Kolan | okay | 04:04 |
| Kolan | than I'll go for EXT3 on all my partitions | 04:04 |
| jurjenst | I had some real problems deleting 200k files from a ReiserFS once... I don't recommand that FS to anyone | 04:05 |
| jurjenst | it could be better with the newest version of it but it was a pain.. took several hours to delete the files | 04:05 |
| jurjenst | What is the experience here with checks of EXT3 when the server is reset 20 times? Do you disable the check or just let all the users wait till it is finished? | 04:08 |
| Kolan | where can I find documentation on the server version? I'm thnikn of installation.. | 04:09 |
| Kolan | or when I get to boot: | 04:10 |
| Kolan | shall I run: server | 04:11 |
| jurjenst | Kolan: server installs only the minimal software... | 04:11 |
| jurjenst | no X, Gnome or KDE | 04:11 |
| jurjenst | so you login on the prompt and install whatever you like to run | 04:12 |
| jurjenst | something like: apt-get install mysql-server phpmyadmin | 04:13 |
| Kolan | hmm.. I was thnikin of when booting a server iso CD and get to the installation "boot:" prompt | 04:13 |
| Kolan | I was just hitting enter | 04:13 |
| infinity | jurjenst: I tend to tune2fs and remove the "maximum mount count", but leave the "maximum mount age", so 30 reboots won't cause a fsck, but rebooting after a long time up will. | 04:16 |
| jurjenst | infinity: thanks... I'm not totally sure what to install on servers... downtime is allways annoing ubuntu drake boots up fast... that is really nice... | 04:24 |
