  ./configure --prefix=/works/nginx --with-pcre=/works/pcre-8.33 --with-zlib=/works/zlib-1.2.7 --add-module=/works/ngx_cache_purge-2.1

 make && make install

7、配置 nginx.conf

    }

    server {

               error_page 405 =200 /purge$1;
         }
         if ( $request_method = "PURGE" ) {
 		   rewrite ^(.*)$ /purge$1 last;
	 }


        location / {
            proxy_set_header Host $host;

            proxy_pass http://my_server_pool;
 
         }
         

    }


}

8、启动nginx sbin/nginx

#用于清除缓存,假设一个URL为http://xxx.test.com/test.gif,通过访问
    #http://xxx.test.com/purge/test.gif可以清楚该url的缓存
