业务需求nginx对后端tomcat(静态文件)做缓存 减轻后端服务器的压力
# nginx-1.6.2.tar.gz ngx_cache_purge-2.3.tar.gz
#编译安装
./configure --add-module=../ngx_cache_purge-2.3 --prefix=/usr/local/nginx --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module
make && make install
#安装ngx_cache_purge后 必须重启nginx才能生效(reload无效 报错 unknown directive "proxy_cache_purge")
