缓存方式解决wordpress后台管理访问速度慢的问题

1、WORDPRESS简介
WordPress 功能强大、扩展性强，这主要得益于其插件众多，易于扩充功能，基本上一个完整网站该有的功能，通过其第三方插件都能实现所有功能；
wordpress有强大的社区支持，有上千万的开发者贡献和审查wordpress，所以wordpress是安全并且活跃的。
2、后台访问速度慢的原因
由于静态化较差，确切地说是真正静态化做得不好，所以在访问后台的时候wordpress会加载很多接口信息。
当你登陆wordpress后台的时候，它会连接wordpress官方接口，获取程序更新，主题更新，插件更新，语言包更新等，由于wordpress官方服务器在国外，所以说国内用户访问加载极其缓慢，有时候直接假死。
3、解决方法
我们需要做的就是屏蔽掉无用的后台查询功能，把以下代码添加到你当前主题目录下的函数文件functions.php中：

如果提示：出现在您保存修改前，您需要将此文件设置为可写。参见CODEX来获取更多资讯。
解决方法如下
首先需要你有root权限，SSH登录，进入到wp的安装目录：
<span class="token function">cd</span> /var/www/

这里主要是找到自己的wp-content目录，不同的人不一样，我的在wwwroot下，找到后直接chomd赋予权限即可！

修改后发现以及可以更新了！

如果之前代码添加出错可添加如下代码
// 后台禁用Google Open Sans字体，加速网站
