events {
    use   epoll;             #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能
    worker_connections  1024;#单个后台worker process进程的最大并发链接数
    # multi_accept on;

    default_type  application/octet-stream;
    #设定日志格式
    access_log    /var/log/nginx/access.log;
    #sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，
    #必须设为 on,如果用来进行下载等应用磁盘IO重负载应用，可设置为 off，以平衡磁盘与网络I/O处理速度，降低系统的uptime.
    sendfile        on;
    #tcp_nopush     on;
