Nginx配置文件详解

# 配置可启动nginx的用户
#user  user [group];
#不限制用户则可注释user行，或像如下配置：
#user nobody nobody;
#user  nobody;

#配置nginx工作进程数，一般与cpu核数相同
#worker_processes  number | auto;
worker_processes  1;

#配置错误日志存放路径及错误日志输出级别(debug,info,notice,warn,error,crit,alert,emerg)
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#配置pid存放路径
#pid        logs/nginx.pid;

#引入其他配置文件，file支持相对路径
#include file;

events {
    #开启nginx进程接收链接序列化，防止多个进程对连接的争抢。默认为on。只能配置在events中
    #accept_mutex on | off;
    #配置是否开启每个work process同时接收多个新到达的网络连接，默认为off。只能配置在events中
    #multi_accept on | off;
    #配置强制使用某种事件驱动模型来处理网络消息。method包括：select,poll,kqueue,epoll,rtsig,/dev/poll,eventport。只能配置在events中
    #use method;
    worker_connections  1024;
}

    #服务日志可是定义，只能在http块中配置
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

    #服务日志存放路径定义
    #access_log  logs/access.log  main;

    #用于开启或关闭使用sendfile()传输文件
    sendfile        on;
    #配置每个work process每次调用sendfile()传输的数据量最大值；若为0则不限制
    #sendfile_max_chunk size;
    #tcp_nopush     on;

    #配置nginx与用户建立连接会话后，nginx保持这个连接打开的一段时间(单位s)
    #keepalive_timeout  timeout[ header_timeout];
    keepalive_timeout  65;
    #该指令用于限制用户通过某一连接向nginx服务器发送请求的次数
    #keepalive_requests number;
