切换到 php7.4 后，phpMyAdmin 完全可以正常工作。这个问题只发生在 php5.6
设置 - Ubuntu 20.04、php5.6、Apache/2.4.41、phpMyAdmin-4.9.5deb2、mysql-8.0.21 php -m（输出）

我已经从发行版中删除了 phpmyadmin 并通过 zip 安装。我收到以下错误。
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
我发现问题在于身份验证方法并将“caching_sha2_password”更改为“mysql_native_password”但我仍然收到上述错误。
