nignx + ngx_cache_purge 配置

1、下载ngx_cache_purge: http://labs.frickle.com/nginx_ngx_cache_purge/

2、下载nginx ：http://nginx.org/download/nginx-1.4.1.tar.gz

3、下载zlib ：http://prdownloads.sourceforge.net/libpng/zlib-1.2.8.tar.gz?download

4、下载pcre ：http://sourceforge.net/projects/pcre/files/pcre/8.33/pcre-8.33.tar.gz/download

5、解压
???? 将上面所有包解压到同一目录。
6、安装
???? 进入解压后的nginx-1.4.1目录，执行。
? ./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

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
