phpmyadmin 连接 mysql 8

phpmyadmin 连接 mysql 8 数据库，出现如下错误：

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

安装 php7.4, 或者按网上的方法，修改 mysql 的加密方式。
