为什么 PHPMyAdmin 有 2 个服务器选择

Question

我用的是虚拟机ubuntu 20.04 我像往常一样在我的 VM 上安装 mysql，但是当我连接到 phpmyadmin 时。它有服务器选择

本地主机：3306

和

本地主机

我不知道我错在哪里，但是当我要连接到3306时，它说

配置禁止无密码登录（参见AllowNoPassword）

我已经更改了 config.inc.php AllowNoPassword = TRUE

当我想用本地主机登录root时，它说

无法登录MySQL服务器

mysqli_real_connect(): (HY000/1698): 拒绝用户 'root'@'localhost' 访问

更新： 我可以在 localhost 服务器上无密码登录 root，但是我可以删除 localhost:3306 服务器吗？
