Nginx配置文件详解

#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

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

# '"$http_user_agent" "$http_x_forwarded_for"';

#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

listen 80;
server_name www.xiaohu.com;
