nginx实现动静分离

1. 要点：
   
2. 配置文件参考：

   user nginx;
   worker_processes auto;
   error_log /var/log/nginx/error.log;
   pid /run/nginx.pid;
   include /usr/share/nginx/modules/*.conf;
   events {
   worker_connections 1024;
   }
   http {
   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  /var/log/nginx/access.log  main;
   sendfile            on;
   tcp_nopush          on;
   tcp_nodelay         on;
   keepalive_timeout   65;
   types_hash_max_size 2048;
   include             /etc/nginx/mime.types;
   default_type        application/octet-stream;
   include /etc/nginx/conf.d/*.conf;
   server {
       listen       80 default_server;
       listen       [::]:80 default_server;
       server_name  _;
       root         /usr/share/nginx/html;
       include /etc/nginx/default.d/*.conf;
       location ~* ^.+.(ico|gif|bmp|jpg|jpeg|png|swf|html|css|js)$ {
           proxy_pass http://192.168.8.83:80;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
       }
       location ~* ^.+.(?![ico|gif|bmp|jpg|jpeg|png|swf|html|css|js])$ {
           proxy_pass http://192.168.8.84:80;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
       }
       error_page 404 /404.html;
           location = /40x.html {
       }
       error_page 500 502 503 504 /50x.html;
           location = /50x.html {
       }
   }
   }
