配置文件的结构解析

#user  nobody;
    worker_processes  1; #工作进程：数目。根据硬件调整，通常等于cpu数量或者2倍cpu数量。
     
    #错误日志存放路径
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;
     
    #pid        logs/nginx.pid; # nginx进程pid存放路径
     
     
    events {
        worker_connections  1024; # 工作进程的最大连接数量
    }
     
     
    http {
        include       mime.types; #指定mime类型，由mime.type来定义
        default_type  application/octet-stream;
     
        # 日志格式设置
        #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; #用log_format指令设置日志格式后，需要用access_log来指定日志文件存放路径
    					
        sendfile        on; #指定nginx是否调用sendfile函数来输出文件，对于普通应用，必须设置on。
    			如果用来进行下载等应用磁盘io重负载应用，可设着off，以平衡磁盘与网络io处理速度，降低系统uptime。
        #tcp_nopush     on; #此选项允许或禁止使用socket的TCP_CORK的选项，此选项仅在sendfile的时候使用
