因此，我在运行Ubuntu 14.04LTS的Linux机器上安装了Xampp。现在突然发现，当我尝试连接到phpmyadmin时，它拒绝连接。我也已经单独安装了MySQL，但它似乎不起作用。有解决此问题的方法吗？

我得到的错误是：

MySQL said:

Cannot connect: invalid settings. Connection for controluser as defined in your configuration failed. phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

有没有发生这种情况的原因和解决办法？
