nginx性能优化
1.worker_processes n;
nginx 进程数，一般为cpu的倍数
2.worker_cpu_affinity 00000001 00000010 ..
为每个进程分配cpu，可多写几个，也可将一个进程分配到多个cpu
3. worker_rlimit_nofile 65535;
nginx进程打开的最多文件描述符数目，查看linux系统文件描述符的方法
[root@ray ~]# sysctl -a | grep fs.file fs.file-max = 1599020 fs.file-nr = 10240 0 1599020
4.use epoll
使用epoll的I/O模型
5.worker_connections 65535;
每个进程序允许的最多连接数，理论上每台服务器的最大连接数为 worker_processes * worker_connections
6.keepalive_timeout 60;
keepalive超时时间
7.client_header_buffer_size 4k;
客户端请求头部的缓冲区大小，一般设置为系统分页大小的倍数。
[root@ray ~]# getconf PAGESIZE 4096
8.oepn_file_cache max=65535 inactive=60s;
为打开文件指定缓存,max值一般和打开文件数以值，inactive 指经过多长时间文件没被请求后删除缓存
9.open_file_cache_valid 80s;
多长时间检查一次缓存的有效信息
10.open_file_cache_min_uses 1;
