    	index.html # 默认首页
    	
    logs # nginx默认日志路径
    	error.log # 错误日志
    	nginx.pid # nginx进程号
    	access.log #nginx访问日志

    # 检查配置文件正确性
    ./nginx -t 
    
    # 检查指定配置文件正确性
    ./nginx -t  -c /usr/local/nginx/conf/nginx.conf

### 基础配置 ###

#user  nobody;
    worker_processes  1;
    
    # 全局的配置，注释的是默认
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;
    #pid        logs/nginx.pid;
    
    
    events {
        use epoll; # linux加上这个, 采用epoll模式
        worker_connections  1024;
    }
    
    
    http {
        include       mime.types;
        default_type  application/octet-stream;
    
        # 默认的日志模版叫man
        #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
        #                  '$status $body_bytes_sent "$http_referer" '
        #                  '"$http_user_agent" "$http_x_forwarded_for"';
    
        # 使用man日志模版
        #access_log  logs/access.log  main;

        #keepalive_timeout  0;
        keepalive_timeout  65; # 连接的超时时间
