       ; Unix user/group of processes
       ; Note: The user is mandatory. If the group is not set, the default user's group
       ;       will be used.

   [nginx-stable]
   name=nginx stable repo

   [nginx-mainline]
   name=nginx mainline repo

   配置解析php

   location ~ .php$ {
       root           html;
       fastcgi_pass   127.0.0.1:9000;

       fastcgi_param  SCRIPT_FILENAME  /ust/Nginx/nginx/html$fastcgi_script_name;
       include        fastcgi_params;
   }

 虚拟机

1. 虚拟主机

   最少要有listen，基于端口区分

       server {
           listen 8002;
           root /opt/nginx/web2;
       } 

   基于域名区分，在监听端口时，可以指定默认主机；

       server {
           listen 8000;
           server_name web1.donatello.cc;
           root /opt/nginx/web1;
       }   
   
       server {
           listen 8000 default_server;
           server_name web2.donatello.cc;
           root /opt/nginx/web2;
       }   
   
       server {
           listen 8000;
           server_name web3.donatello.cc;
           root /opt/nginx/web3;
       }  

2. location
   语法规则：

   synopsis:  location [=|~|~*|^~]  /uri/ {}
   =   精确匹配
   ~   区分大小写
   ~*  不区分大小写
   ^~  禁止表达式匹配

   ftp 目录浏览

       server {
           listen 8000 default_server;
           server_name web2.donatello.cc;
           root /opt/nginx/web2;
   
           location /ftp {
               autoindex on; 
           }   
           location /data {
   
           }
       }

代理&Http负载均衡

1. 代理配置，转发到其他主机的指定端口

   location / { 
       proxy_pass http://donatello.cc:80;
   }

2. 负载均衡
   要使用 http 负载均衡，须在 nginx 配置文件 http 指令中使用 upstream 指令定义后台服务器组

   server {
       listen       80; 
       server_name  localhost;
   
       location / { 
           proxy_pass http://pinyou;
       }   
   
   }
   
   
       upstream pinyou {
           server www1.com:800;
           server www2.com:800;
           server www3.com:800;
           server www4.com:800;
       }   

   简单粗暴的回话保持

       upstream pinyou {
           ip_hash;
           server www1.com:800 weight=1;
           server www2.com:800 weight=2;
           server www3.com:800 weight=3;
           server www4.com:800 weight=1;
       }  

   NGINX Plus offers better solutions if session persistence is required.

       upstream pinyou {
           zone backend 64k;
           least_conn;
           server www1.com:800 weight=1;
           server www2.com:800 weight=2;
           server www3.com:800 weight=2;
           server www4.com:800 weight=1;
       } 

   保险的方式，引入恢复的上游服务器：

   server www1.com:800 weight=1 slow_start=30s;

3. Nginx Plus
   Http KeepAlive，Nginx可以保留与上游服务器的 tcp 连接，从而提供响应速度。

   server {
       listen 80;
       location / {
           proxy_pass http://pinyou;
           proxy_http_version 1.1; # 1
           proxy_set_header Connection ""; # 2
        }
   }
   
   upstream backend {
       server server www1.com:800;
       server server www2.com:800;
   
       # maintain a maximum of 20 idle connections to each upstream server
       keepalive 20; # 3
   }
