标准配置文件详解

#main 全局配置
#user  nobody; #主模块命令，指定Nginx的worker进程运行用户以及用户组，默认由nobody账号运行
worker_processes  1; #指定Nginx要开启的进程数
# worker_rlimit_nofile 100000; #worker 进程的最大打开文件数限制
#error_log  logs/error.log; #用来定义全局错设日志文件的路径和日志名称
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid; #Nginx进程id的存储文件位置

#设置nginx的工作模式以及连接数上限
events {
    worker_connections  1024;#设置nginx每个进程最大的连接数，默认是1024
}

#http服务器相关属性配置
http {
    include       mime.types;#主模块命令，对配置文件所包含文件的设 定，减少主配置文件的复杂度，相当于把部分设置放在别的地方，然后在包含进来，保持主 配置文件的简洁
    default_type  application/octet-stream;#默认文件类型，当文件类型未定义的时候就使用这类设置的

    #指定nginx日志的格式
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on; #开启高效文件传输模式，避免内核缓冲区数据和用户缓存区数据之间的拷贝
    #tcp_nopush     on; #开启 TCP_NOPUSH 套接字（sendfile 开启时有用）

    #keepalive_timeout  0; 客户端连接超时时间
    keepalive_timeout  65;

    #gzip  on; 设置是否开启gzip模块

    #虚拟主机配置
    server {
        listen       80; #虚拟主机的服务端口
        server_name  localhost;#用来指定ip或者域名，多个域名用逗号分开

        #charset koi8-r;

        #URL匹配特定位置后的设置
        location / {
