WordPress加速网站的方法

WordPress网站优化是主题开发者必须处理好的问题，只有提升了主题站的运行速度，才能使网站在不落后别人一部，所以今天我们就用网站中的Nginx缓存进行主题站点加速的方法教学，大家可以一起学习一下：

一般Nginx配置fastcgi cache。fastcgi_cache的好处是大部分用户的请求不用后端php-fpm打交道，直接发送缓存的静态页面

自从使用了nginx缓存，网站平稳运行，再也没有出现过宕机的现象。同时vps的cpu和内存占用率直线下降，再也无需担心vps的配置问题，感觉再来10倍流量博客也撑得住！

因为nginx稳如狗的体验，所以现在对于博客类读多写少的产品都是强推nginx缓存（fastcgi缓存或者proxy缓存）。鉴于可能帮到一些网友，现贴出 /etc/nginx/nginx.conf 配置文件供大家参考（包含ssl设置和gzip部分）：
