Title: Php-fpm
Post by: lupetalo on 2012-12-28, 04:30:24

What is optimal template for using with large number of users (150+)? My memory always get swamped and all domains are always using some part of it...

Better use small users (with large domains) rather than large users (with small domains).

It's because (by default) php-fpm refer to user rather than to global or domains.

You can see setting for every user inside /etc/php-fpm.d

I know that, but question is how to optimise current situation :)
I tried lowering:

Code: [Select]

pm.max_requests = 200but it not help a lot...
Is it possible to kill those process that are not active but taking memory? I only have ~20 regulary active users at all times.

This is example for my modified for /home/php-fpm/tpl/custom.php53-fpm-pool.conf.tpl

Code: [Select]

<?php
    $userinfo = posix_getpwnam($user);

    if ($userinfo) {
        $fpmport = (50000 + $userinfo['uid']);
    } else {
        return false;
    }

    if ($user == 'apache') {
        $pool = 'default';
    } else {
        $pool = $user;
    }

    if ($user === 'riginta') {
        $startserver = '20';
        $minspareserver = '20';
        $maxspareserver = '40';
        $maxchildren = '200';
    } else {
        $startserver = '2';
        $minspareserver = '2';
        $maxspareserver = '4';
        $maxchildren = '10';
    }

Can you please tell mi what is changed and will it kill not active processes?

Title: Re: Php-fpm

That did opposite, memory fills in just few minutes, every process for every user is takeni even more memory....
1.4% of memory or 152.52 Mb per user, that is too much....

You can try something like:

Code: [Select]

       $startserver = '2';
        $minspareserver = '2';
        $maxspareserver = '4';
        $maxchildren = '4';

Ended up with creating script which checks for free memory and if below 200mb restart php-fpm. Takes 2 sec and it is not noticable a lot. But for two weeks on two occasions restart did not worked without any real reason. service php-fpm restart did not kill all php-fpm processes.
