#user  nobody;  ##配置用户或者组
worker_processes  1; ##允许生成的进程数，一般设置和cpu核数一样

##制定日志路径，级别。这个设置可以放入全局块，http块，server块，级别依次为：debug|info|notice|warn|error|crit|alert|emerg
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid; ##PID文件，记录当前启动的nginx的进程ID


events {
    worker_connections  1024; ##单个后台worker process进程的最大并发链接数
}


http {
    include       mime.types;  ##设定mime类型(邮件支持类型),类型由mime.types文件定义
    default_type  application/octet-stream; ##默认文件类型

    ##自定义日志格式
    #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 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;

    #keepalive_timeout  0;
    keepalive_timeout  65; ##连接超时时间，可以在http，server，location块。

    #gzip  on;

    server {  #一个Server节点就是一个虚拟主机 vhost
        listen       80; #监听的端口号
        server_name  localhost; #服务器地址，主机名/ip/域名都可

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        ##请求的url过滤，正则匹配，~为区分大小写，~*为不区分大小写。例如：location  ~*^.+$ {
        location / {
            root   html;   #静态资源路径 比如 /path/www/dist;   一般来说，访问dist/index.html文件，如果访问不到页面需加 try_files    $uri    $uri/    /index.html; 
            index  index.html index.htm;
        }
