wordpress数据库建立失败

将wordpress文件夹放入共享云虚拟主机后，远程通过浏览器访问wordpress文件夹，出现“请在下方填写您的数据库连接信息”的提示。正确填写信息后，点击“提交”，出现“Internal Server Error”的错误，具体错误内容如下：
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@bxu2344600133.my3w.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

请问这个问题该如何解决呢？我是个菜鸟，谢谢大家的帮助。我想重启虚拟机试试，但不知道如何重启……
