nginx.conf默认配置：

[[email protected] conf]# cat nginx.conf

# 全局块
#user  nobody;
worker_processes  1; #工作线程数，一般设置为CPU个数*单个CPU核数

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


# events块
events {
    worker_connections  1024; #一个子进程最大允许连接数
}


# http块， 配置http服务器
http {
    include       mime.types; #引入的文件
    default_type  application/octet-stream;

    # 定义日志格式： main是格式名称，默认格式，也可以添加自定义格式
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    # main格式记录的内容是：
    # 远程IP - 远程用户[用户时间] 请求方法(如GET/POST)和协议
    # 状态  请求体body长度  referer来源信息
    # 用户代理  被转发的请求的原始IP 
    # 注: http_x_forwarded_for:在经过代理时,代理把你的本来IP加在此头信息中,传输你的原始IP

    #access_log  logs/access.log  main; #设置访问日志，第一个参数指定日志文件，第二个参数指定日志文件使用的格式

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65; #客户端与nginx的长连接时间,单位秒,设置为0则禁用
    server_tokens   off; #报错时不显示Nginx版本号

    #gzip  on;
