使用Tiup部署TiDB机器的时候，报SSH错误

为提高效率，请提供以下信息，问题描述清晰能够更快得到解决：

【TiDB 版本】
tidb-community-server-v4.0.10-linux-amd64.tar

【问题描述】
tiup cluster check /home/tidb/cluster/topo.yaml --user tidb -i /home/tidb/.ssh/id_rsa

检查的时候报错，但是从中控机到其他机器的SSH已经是互通的

With great power comes great responsibility

用的什么用户，有 sudo 权限吗

[懂的都懂 (wangtianyi)]

@inner

sudo: no tty present and no askpass program specified

建议您在提问之前在 asktug 里面搜索一下。很多这样的帖子。

用的是tidb用户，没有给这个用户添加sudo权限，加上就好了，非常感谢

有 sudo ， 有 ssh 权限， ssh 命令 需要 用 -p指定端口，安装时 是这么做的么。。

1、sudo加个root免密权限/etc/sudoers

2、在中控机上查看使用ssh tidb@IP是否能切换到对应节点上如果不能需要做下ssh互信
