哪个php5-fpm设置用于高并发连接数+ nginx

Question

请帮我调整我的 php5-fpm 和 nginx 配置。

问题是我的 php5-fpm 日志不断报告缓慢的脚本并杀死一个子线程。

专用服务器，四核至强，32Gb 内存。1 个 php 应用程序/站点正在运行。

Php 应用程序：坚果壳，搜索引擎，结果触发 curl 请求。每次搜索页面加载时间通常为 2 - 3 秒。

这是我认为正在发生的事情：

我有 750 个并发 php 用户在执行搜索。pm.max_children = 400由于 RAM 限制，我只能设置。我假设每个用户（子线程）有 50Mb，所以 = 20GB。我假设每个用户 = 1 个子线程。因此，pm.max_children这不足以涵盖 750 个需要 3 秒进行搜索的活跃 php 用户。

所以我想我看到用户排队是因为我看到 3 秒变成了 4 - 7 秒。当用户排队时，我认为脚本越来越慢会触发错误日志消息，而 php5-fpm pm 会杀死孩子吗？

这就是我认为正在发生的事情。我在下面提供了我的错误日志输出、nginx、php5-fpm 配置。

如果我可以调整我的配置，并且确实pm.max_children应该至少等于您的最大并发用户数，我真的很感激任何建议，请记住，我的 php 搜索打开了大约 3 秒。我需要更多的内存还是额外的服务器？

这是我的记忆，但我在大约 30 分钟前才重新启动了 nginx

:/var/log# free -m
             total       used       free     shared    buffers     cached
Mem:         32151      26175       5975          0        186      13334
-/+ buffers/cache:      12654      19496
Swap:        32739          5      32734

php5-fpm: www.conf: 进程管理器设置为静态

我使用静态是因为我认为所有孩子都可以立即使用而不是生成时间，而且我只在盒子上运行 1 个应用程序。

;pm = dynamic
pm = static

;pm.max_children = 10
pm.max_children = 400


;pm.start_servers = 4
pm.start_servers = 150


;pm.min_spare_servers = 2
pm.min_spare_servers = 32


;pm.max_spare_servers = 6
pm.max_spare_servers = 64


;pm.max_requests = 500
pm.max_requests = 10000

php5-fpm 日志中的错误

我应该澄清一下，我在高负载下看到的行为，一次 750 个用户是缓存和未缓存的搜索结果开始花费更长的时间。即缓存> 1 秒，非缓存> 4 到7 秒。因此，当用户排队等待时，我认为搜索时间会增加，并且会在负载下脚本运行缓慢。触发通知，孩子就会被杀死。

例如，这是在重新启动后

Answer 1

我还不能发表评论（没有足够的代表），所以我会发布一个答案：最好也有你的 nginx 日志。

关于您的 pool.d/www 配置：如果您将 pm 置于静态，则大多数变量不会产生任何影响， max_children 主要会影响您的设置。( http://php.net/manual/en/install.fpm.configuration.php ) 尝试使用PM“ondemand”。

您不应该从那么高的 pm.start_servers 开始。您也应该降低您的 min_spare_servers。

关于您的 nginx 配置： http://wiki.nginx.org/CoreModule#worker_processes "max_clients = worker_processes * worker_connections"

您的值“worker_rlimit_nofile”对我来说看起来不正确。

查看http://wiki.nginx.org/CoreModule#worker_cpu_affinity也可以使用所有核心。
