我已经安装了ngix PHP5-fpm.我很高兴,但我不能优化PHP5-fpm,以便它可以正常工作.每个固定错误都会产生不同的错误.

首先,我有默认设置,导致很多错误：

[04-Jun-2012 03:30:06] WARNING: [pool www] server reached pm.max_children setting (5),consider raising it

我增加了所有数字：

pm.max_children = 15
pm.start_servers = 5
pm.min_spare_servers = 3
pm.max_spare_servers = 5
;pm.max_requests = 500

它导致了一个不同的错误：

[28-Feb-2013 07:45:06] WARNING: [pool www] seems busy (you may need to increase pm.start_servers,or pm.min/max_spare_servers),spawning 8 children,there are 18 idle,and 28 total children

我再次增加了所有数字：

pm.max_children = 70
pm.start_servers = 20
pm.min_spare_servers = 20
pm.max_spare_servers = 35
;pm.max_requests = 500

这导致日志文件填满了这个：

[28-Feb-2013 13:21:55] NOTICE: [pool www] child 21868 exited with code 0 after 4171.293476 seconds from start
[28-Feb-2013 13:21:55] NOTICE: [pool www] child 23962 started

我没有注释：

pm.max_requests = 500

我有同样的错误,但不是经常 – 每5分钟：

[28-Feb-2013 13:21:55] NOTICE: [pool www] child 21868 exited with code 0 after 4171.293476 seconds from start
[28-Feb-2013 13:21:55] NOTICE: [pool www] child 23962 started

我确实再次增加：

pm.max_requests = 1000

现在我每小时有2-3次这个错误,但它仍然存在.

我会再次增加这个数字,但我觉得我的服务器(网站)的工作速度比在其他服务器上托管的网站有点慢：pm.max_children = 15,pm.start_servers = 5,pm.min_spare_servers = 3,pm.max_spare_servers = 5.(可能这只是一个网络问题,我不知道).

我搜索了谷歌和这个网站,知道如何计算pm.max_children(它取决于RAM).但我找不到任何有关如何计算的信息：

    pm.start_servers
    pm.min_spare_servers
pm.max_spare_servers
    pm.max_requests

有人可以帮忙吗？

我没有更改Nginx配置文件中的任何内容.
