我已经安装了xampp，并且能够去phpmyadmin。
但是，我已经安装了mysql workbench（在xmpp之后），并且当我想启动mysql时，我在mysql日志中看到以下消息：您是否已经在端口3306上运行了另一个mysqld服务器？。我尝试更改my.ini中的端口，此问题已解决，但现在当我想转到phpmyadmin时，它说access denied并抛出了很多错误。
错误是：
MySQL说：文档
**
Cannot connect: invalid settings.
mysqli_real_connect(): The server requested authentication method unknown to the client [caching_sha2_password]
mysqli_real_connect(): (HY000/2054): The server requested authentication method unknown to the client
Connection for controluser as defined in your configuration failed.
mysqli_real_connect(): The server requested authentication method unknown to the client [caching_sha2_password]
mysqli_real_connect(): (HY000/2054): The server requested authentication method unknown to the client
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.
** 我删除了xampp一次，我将其安装为agian，但无法解决该怎么办？
