Обсуждение: Gentoo for production DB server?
Hello: At the risk of starting a flame-war, I'd like some more details on the use of Gentoo Linux for a production PostgreSQL server. There have been a couple of comments lately that it is not such a great idea; does anyone have specific experience they'd be willing to share? Some background: we've been running PostgreSQL on assorted versions of Red Hat for a couple of years. RedHat Enterprise is not an option, so we currently have a mix of Fedora, RH 9, White Box Enterprise (a RedHat clone), and Gentoo, and want to settle on a single distro, with White Box and Gentoo the leading contenders. Hardware is mostly Dell PowerEdge or white-box. I prefer to build PostgreSQL from source anyway, so package management is not as important as stability and ease of maintenance/updates. Most of what I've read says that Gentoo is either the greatest thing since sliced bread or not ready for primetime; in either case, details are sketchy. I would like to hear especially from people who are either running Gentoo in production or have tried and rejected it. Thank you.

I used Gentoo for a long time on my home systems but I recently quit. It's a "fun" distro as far as the options and all, and it has a great user community for support.. but I got tired of the Gentoo developers (whether intentional or not) pushing out new stuff marked as "stable" when it obviously was not. The price was right and I knew going in I wasn't getting a perfectly stable distro, but nevertheless they left me with a broken machine on several occasions. Having a slightly faster machine isn't worth the headaches to me personally. For stability, db/web server usage and such, I'd go with Debian. For features, desktop systems, etc., I'd go with Suse. 9.1 is impressive. For security, firewall, or router usage, I'd go with *BSD. -- Greg Donald
I've been extremely happy with my gentoo boxes. I switched from Slackware over the past year or so after many years of Slackware zealotry. I have nothing bad to say about using Gentoo other than I personally wouldnt use portage/ebuilds for PostgreSQL. Personally I always have better experiences when I download the source tarball and install things like PostgreSQL the way the developers distribute them.

We were using Gentoo until recently on production servers, and still do on some development machines. I've never had a problem with it, and would recommend it if you know what you're doing; only upgrade packages when you really need to, don't do emerge -u world/system, preferably perform updates on an exact mirror, test well, then switch servers, and sync up. If you treat it kindly, Gentoo will treat you kindly. We've now switched to RHEL3 (management decision - for support!), which IMHO is an admin nightmare (but thats just RPM's for you). We had to download and compile several important packages manually, the supplied PostgreSQL was very out of date, and PHP didn't even have PostgreSQL support builtin. You also don't have to install tons of unused crap, like X11. Provided you don't have management breathing down your neck about operating system support, and you know your way around a Linux system without a mouse, then I'd heartly recommend Gentoo. -- Mark Gibson <gibsonm |AT| cromwell |DOT| co |DOT| uk> Web Developer & Database Admin Cromwell Tools Ltd.

They provide a way for you to add unstable packages using ACCEPT_KEYWORDS="~x86". I never used the command because I never _wanted_ unstable packages. Seems I got them anyway. -- Greg Donald

RPMS for RHEL 3 is available on PostgreSQL FTP mirrors...
Also, if you want PostgreSQL support in PHP, you should install php-pgsql
rpm, provided in the CDs.

Agreed :(

Actually, FreeBSD is an outstanding platform for stability as well. They offer -current, -stable, and security branches depending on how much instability you can tolerate. -- Jim C.

Having a slightly faster > machine isn't worth the headaches to me personally. I too fiddled with it at home for a while. I saw a few benchmarks showing Gentoo was actually slower than Redhat and Mandrake - then I really wasn't sure why I was compiling for days. :) Yes, I know you don't have to compile everything. Yes, I realize those benchmarks weren't the most scientific. We use Redhat in production. When it came to decision time, the only real contenders were Redhat and Suse, because we wanted someone else to QA our operating system (not our business focus - that would cost us more than the OS) and we needed the best hardware vendor support. We picked Redhat over Suse primarily because everyone in our organization had Redhat experience (and on their desktops) but no Suse experience - otherwise I probably would've gone with Suse. I'm really tired of poor file system diversity on Redhat.

The worst thing is to have not done an 'emerge world' in 2 months, only to discover that there are now 99 pending updates. The biggest problem is not the technology of Gentoo (the ebuild system / portage is cool), but its the maintainers. It's very much of a bleeding-edge atmosphere... These days all my servers are either RHES or Debian-stable. All in all, debian is one of the best server platforms out there in the 'free' world, IMHO. I've been exceedingly pleased with it. I love the attention to detail and security, and yet they still let you have plenty of customization power. -Barry

You see the entire reason I was updating was because of a security patch for sshd. The chain of dependencies in this case (eg. sshd -> glibc -> gcc), mandated that I wound up needing to do a fairly substantial emerge. Don't get me wrong, I like Gentoo as a technology, I just personally think its not ready for use in production servers. -Barry
