这是一个很逗(Sha)比的错误，在一个很无聊的时间，发生在一个很无聊的人身上。

由于某些测试，折腾需求，去尝试申请QQ互联应用，验证需要验证首页Header，添加meta标签。

然后我像逗比一样的吧header（和跳转一样）直接写index.php里了，没想到触发后整个应用会503。

听说Radhat维护了。。。。

然后我准备等等看看。

 

两天后。。。。。

 

还是503。。各种503。。重启应用还是503，刚重启好，挂了，刚重启好，挂了，结果后来重启，打开博客一看：“数据库链接错误”，顿时吓Die了，难道又是什么神秘的BUG？还是维护后遗症？再次重启，提示mysql某文件被锁定，我还去谷歌了半天。

好的，后来开这VPN访问博客SFTP，查看日志，诶我擦，不会吧。。

以上省略

以下省略

于是结果出来了，就是首页index.php的一句话错了，（不知道为什么）整个应用就503，然后Stopped了。

然后开启后，百度的云观测，dnspod之类的监控就爬过来看看恢复了没有。

然后又触发了，又死了。。

于是来来回回折腾几次，终于开SFTP吧万恶的代码删了。

（index，我还是改成HTML做302跳转吧，等号给tx验证header。）
