Error: Failed to initialize TiDB environment on remote host ‘10…233’ (task.env_init.failed)
caused by: Failed to create new system user ‘tidb’ on remote host
caused by: Failed to execute command over SSH for ‘appdeploy@10…233:22’
caused by: Process exited with status 1
ssh免密是可以登录的
麻烦参考此文档先检查下，多谢。
已经按这个方式赋权了，用免密登录报这个
Error: Failed to initialize TiDB environment on remote host ‘10…233’ (task.env_init.failed)
caused by: Failed to create new system user ‘tidb’ on remote host
caused by: Failed to execute command over SSH for ‘appdeploy@10…233:22’
caused by: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none], no supported methods remain
用密码是报下面的错

caused by: Failed to create new system user ‘tidb’ on remote host
caused by: Failed to execute command over SSH for ‘appdeploy@10…233:22’

1.请问具体使用的哪个用户免密？免密是如何做的，如何确认免密没有问题？
2.部署的命令是什么？
是单机部署
tiup cluster deploy icss_tidb4 v4.0.1 ./topo.yaml --user appdeploy -p
直接在本机是可以登录的
[appdeploy@1zzzz ~]$ ssh 10…233

[appdeploy@1zzzz ~]$
可以提供下 debug 日志看下，
–user 需要在所有 tidb 节点免密互信，可以尝试在中控节点使用 ssh appdeploy@10…233 是否可以登陆，其他节点类似操作
在10.****.233 执行 tiup cluster deploy icss_tidb4 v4.0.1 ./topo.yaml --user appdeploy -p

请问命令里使用的appdeploy 是否有足够权限，能否尝试用 root 用户部署，多谢
系统默认root没ssh权限，问题已经解决了，是app这个账号没有sudo权限导致，加上sudo权限就好了。谢谢！
我使用了root用户 也看到/etc/sudoers 文件中有sudo权限 但是还是报同样的错误，请大神指教tiup-cluster-debug-2020-10-29-10-25-52.log (26.0 KB)
