Nginx reverse proxy, dynamic static request separation, and Nginx cache application, and use Ngx_cache_purge to clear the specified URL

One, Nginx reverse proxy configuration

#tomcat Java code upstream tomcat_server{server 127.0.0.1:8080;   } erver{listen 80;      server_name www.wolfdream.com;         Location/{proxy_redirect off;         Proxy_set_header Host $host;         Proxy_set_header X-real-ip $remote _addr;         Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;      Proxy_pass Http://tomcat_server; }

It is obvious that the user accesses the www.wolfdream.com (you need to set the local localhost and point www.wolfdream.com to Nginx's IP) ( or write the www.wolfdream.com directly at the IP address where the nginx resides, and transfer the request to a Tomcat server in the background, that is, 127.0.0.1:8080, and send the requested data to the client

two, dynamic static request phase separation

God horse meaning. Pictures, js,html and other static things to access a dedicated server, while the dynamic request to access another server. As simple as this, on the example:

  Java code    server {          listen        192.168.154.128:80;          server_ name  image.wolfdream.com;    index index.html;             #proxy_pass  http://tomcat_server;                       #charset  koi8-r;               #access_log   logs/host.access.log  main;                              location / {               root   html;                #index   index.html index.htm;                 proxy_redirect off;          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 ~ .*\. (gif|jpg|jpeg|png|bmp|swf) $   {               valid_referers none blocked 192.168.154.128 192.168.154.1;        if  ($invalid _referer)        {           rewrite ^  /403.jpg break;        }                                    if  (!-f  $request _filename)  {                     rewrite ^ /404.jpg last;  <
