请帮我调整php5-fpm和nginx的配置.
问题是我的php5-fpm日志不断报告慢脚本并杀死子线程. 专用服务器,quad xeon,32Gb Ram. 1个php应用程序/站点运行. Php应用程序：Nutshell,搜索引擎,结果触发curl请求.每次搜索的页面加载时间通常为2-3秒. 这就是我认为正在发生的事情 所以我认为我看到用户排队,因为我看到3秒变成4-7秒.由于用户排队我认为脚本越来越慢触发错误日志消息而php5-fpm pm会杀死孩子？ 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. 我真的很感激任何关于我是否可以调整我的配置的建议,如果确实pm.max_children应该至少等于你的最大并发用户,请记住我的php搜索打开大约3秒钟.我需要更多内存还是其他服务器？ 这是我的记忆,但我只在大约30分钟前重新启动了nginx :/var/log# free -m

php5-fpm：www.conf： 我正在使用静态,因为我认为所有的孩子都可以立即使用,而不是产生时间,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,我在高负载下看到的行为,一次有750个用户是缓存的搜索结果而不是缓存开始需要更长的时间.即>缓存为1秒,非缓存为4到7秒.因此,当用户排队等待时,我认为搜索时间会增加,并且它会在负载下缓慢运行到脚本运行缓慢的程度.触发通知,孩子被杀. 例如刚刚重启之后 [04-Jun-2013 20:11:07] NOTICE: Finishing ...

php5-fpm通过TCP端口连接 谢谢
我认为你可能运行了太多并发的php进程,但是如果没有更多关于资源瓶颈的信息,很难知道.我想你可能受到磁盘IO和/或CPU的限制,并且所有并行的PHP进程都在竞争这些进程并相互减慢速度.在某些时候,进程切换的开销成为一个重要因素,并且通过运行大量进程可以获得更少的吞吐量而不是更多.您可能也会遇到或担心RAM耗尽并开始交换的情况,这非常糟糕.信任nginx能够将请求排队并保持更高的吞吐量更快的请求,同时减少它们.
我通常会从5到50个PHP进程中进行任何操作,该范围的两端都有点特殊.通常10-15.对于性能非常高的磁盘系统,以及超过通常的16个核心,拥有更多进程可能是有意义的,但与拥有更多更便宜的服务器相比,这通常是错误的经济.根据我的经验,除非你有很多编写得非常糟糕的代码,否则在一台服务器上并行处理超过15个php进程通常没什么好处,如果有一个好处,它可能是稳定性而不是吞吐量,面对病态长期运行的请求堆积并且不留下备用流程. 如果您有多个具有单独进程池的代码库,则可能需要大量进程,但每个池可能不需要超过3到5个进程. 你确实需要很多nginx工作者连接来处理静态文件.除了4096之外,不太可能有任何改进,只有在不寻常的情况下你会看到1000和4000之间的差异.(除非你主要服务于静态文件 – 这是一个完全不同的场景,但是因为你正在讨论这个问题上的php进程我不认为这是这种情况). 我怀疑你的超时时间太长了.如果没有任何结果,请断开连接并继续下一个连接. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
