有一台服务器访问量非常高，使用的是nginx ，错误日志不停报以下错误：

2016/05/16 08:53:49 [alert] 13576#0: accept() failed (24: Too many open files)
2016/05/16 08:53:49 [alert] 13576#0: accept() failed (24: Too many open files)

解决方法：

centos5.3 中 ulimit -n 为1024， 当Nginx连接数超过1024时，error.log中就出现以下错误：

[alert] 12766#0: accept() failed (24: Too many open files)

使用 ulimit -n 655350 可以把打开文件数设置足够大， 同时修改nginx.conf ， 添加 worker_rlimit_nofile 655350； （与error_log同级别）

这样就可以解决Nginx连接过多的问题，Nginx就可以支持高并发。还要修改nginx
