destroy删除集群的时候报错

tiup cluster destroy xxxx
报错如下

Stopping component alertmanager
        Stopping instance 172.16.xx.xx

Error: failed to stop alertmanager: failed to stop: 172.16.xx.xx alertmanager-9093.service, please check the instance's log(/tidb-deploy/alertmanager-9093/log) for more detail.: executor.ssh.execute_failed: Failed to execute command over SSH for 'tidb@172.16.xx.xx:22' {ssh_stderr: , ssh_stdout: , ssh_command: export LANG=C; PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin /usr/bin/sudo -H bash -c "systemctl daemon-reload && systemctl stop alertmanager-9093.service"}, cause: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

看报错是互信的问题，最后定为问题原因是，用户目录下的pubkey和tiup里面的pubkey不一致了。。。

如下解决

ssh-copy-id -i /home/tidb/.tiup/storage/cluster/clusters/tidb-test/ssh/id_rsa.pub 10.0.xx.xx
