关于 WP Rocket 配置
我这里主要讲 web 服务器是 Nginx 的使用方法。
1、下载安装 WP Rocket （下载地址往下看），39 刀正版支持，诸位老板少抽几包烟，尽量支持官方。
2、添加rewite规则到vhost配置文件中。目的就是让web服务器节省在请求动态文件，直接读取生成的静态文件。

以上代码复制保存为 rocket.conf 文件上传到你的 nginx/conf 目录中，然后我们只要在我们的vhsot文件中引入即可。
# BEGIN WP rocket include /usr/local/nginx/conf/rocket.conf; # END WP rocket
然后 Nginx restart 重启一下使文件生效。按照如上配置好之后，查看网站源码，源码最底部就会出现安装成功后的提示如下：
能看到此信息，就说明完事ok了。
PS：当然何先生并没有使用这款插件，而是选择了 WP Super Cache 这款插件，为什么呢？因为这款插件似乎评论者填写评论信息之后再访问网页就不会再访问缓存内容了，而 WP Super Cache 确有这个设置，我是一个强迫症患者，我需要所有人看到的都是缓存，这也是我没有使用这款插件的原因，当然这款插件的优化速度是比 WP Super Cache 要快很多的，看各自舍取吧
