压力测试中的Nginx/PHP-FPM kevent（）错误

G'day

我正在用Nginx（1.2.7_1,1）和PHP-FPM（5.4.12）运行一个FreeBSD盒（9.1-RELEASE）。我在使用Apache AB处理并发请求时遇到了大问题：

ab -n 10000 -c 500 http://10.128.28.164/index.php

我在/var/log/httpd-error.log中得到的主要错误（以千计）是：

2013/03/08 11:11:10[error]99855#0:*44116 kevent（）报告连接到上游时connect（）失败（54：由对等方重置连接），客户端：10.128.28.179，服务器：localhost，请求：“GET/index.php HTTP/1.0”，上游：fastcgi://10.128.28.164:9000，主持人：“10.128.28.164”

如果我浏览到服务器（10.128.28.164），它可以很好地用于HTML和PHP页面

任何帮助都将是惊人的

检查dmesg是否有任何内核消息，大意是网络连接的最大数量、打开的文件或某些其他资源已耗尽（或者达到限制）

您引用的日志消息仅说明代理的部分情况。为什么后端正在重置连接，应该在后端的日志中检查。。。例如，php fpm也可能超出了每个进程对文件描述符的限制——所以请检查日志/php-fpm.log中的错误
