Nginx配置文件详解

标签：nginx

#user  nobody;    登录用户

worker_processes  1;   nginx开启的进程数，一般开启一个就足够，多开几个work进程，可以减少机器io带来的影响，在一般情况下

开启4个或者8个，多开无意

#error_log  logs/error.log;  错误日志目录

#error_log  logs/error.log  notice;

#error_log  logs/error.log  info;

#pid        logs/nginx.pid;   记录nginx pid文件的参数

events {  每个work进程可以处理的连接数 并发连接数

    worker_connections  1024;  如果网站访问量过大，已经超过1024并发数，那么就要修改worker_connecions，这个植越大

并发数也就大，按照实际情况决定，不能设置过多，否则会造成IO负载量过大

}

http {

    include       mime.types;  为文件类型定义文件

    default_type  application/octet-stream; 默认文件类型

    #access_log  logs/access.log  main;  创建访问日志

    sendfile        on;

    #tcp_nopush     on;  开启后会产生一个响应头部信息产生独立的数据包发送，一个响应头一个包

    #keepalive_timeout  0;  保持连接的超时时间

    keepalive_timeout  65;

    #gzip  on; 是否采用压缩
