用rhc找回Openshift 中的 mysql密码

曾经有一份数据库账号密码摆在我面前，我没有珍惜，直到失去了才后悔莫及……╮(￣▽￣”)╭

如果说菜鸟到高手的路就是一条不断减少犯二次数的漫长征程，鉴于我现在还离起点没多远，每周把范过的二拿出来洗一洗估计都能炒一盘菜吃了。

这个博客搭建在redhat的Openshift应用平台上，当初看的教程说安装完phpmyadmin之后会显示数据库信息：

可是我当初手一贱直接就浏览器右上角小红叉然后奔去食堂会红烧肉。之后想要备份数据库到本地并且用localhost链接时才发现……本地数据库连接错误啊！

原来是因为openshift用的mysql数据库名在我本地数据库里不存在。

于是我想啊，如果我用和openshift相同的设置在本地建一个新的数据库，用户名和密码也和openshift的一样，不就可以在本地操作一个和线上完全一样的blog了么？（菜鸟如我也只能想到这么多了，如果有别的方法，请高手指教，多谢~）

可是可是！去Openshift网站My Application里，查！不！到！数！据！库！信！息！啊！(PД`q。)·。’゜

于是经过和英文Doc的一番奋战，终于哼哼哼……

还记得redhat client tool 么？官方建议（也算是强制了）使用的Openshift命令行管理工具，让它帮一帮你吧。

–help是程序员最好的伙伴Shell

    C:\Program Files\PowerCmd>rhc --help

出来这些信息：

    Usage: rhc [--help] [--version] [--debug] <command> [<args>]

    Command line interface for OpenShift.

    Getting started:

      server             Display information about the status of the OpenShift
    service.
      account logout     End the current session

    Working with apps:
      app restart        Restart the application
      app show           Show information about an application
      tail               Tail the logs of an application

看到这句了么 ?

    apps               List all your applications

于是我…

    C:\Program Files\PowerCmd>rhc apps

结果皆大欢喜：
