【 TiDB 使用环境】测试
【 TiDB 版本】v8.1.0
【复现路径】
按照官网文档操作后：https://docs.pingcap.com/zh/tidb/stable/quick-start-with-tidb#在单机上模拟部署生产环境集群
【遇到的问题：问题现象及影响】
外部 mysql 客户端无法连接到tidb，但是本地localhost登录却可以。
连接命令: mysql -h 172...* -u myuser -P 4000;
注意：我并没有设置密码。
报错：Access denied for user ‘myuser’@‘172...’ (using password: NO);
设置了密码也不行，报错：
Access denied for user ‘myuser’@'172...’ (using password: YES);
mysql 版本 :mysql Ver 8.0.39-0ubuntu0.22.04.1 for Linux on x86_64 ((Ubuntu))
