Changing only the password does not affect mutual trust.

If you mean that mutual trust has expired, then copy the content of /home/tidb/.tiup/storage/cluster/clusters/ClusterName/ssh/id_rsa.pub to the ~/.ssh/authorized_keys file on each machine.

Mutual trust can be skipped. Just use the -p parameter to input the password during installation, and all passwords should be the same.

Once and for all
It is recommended to run the script with the root user for mutual trust

./sshUserSetup.sh -user tidb -hosts "192.168.80.131 192.168.80.132 192.168.80.133 192.168.80.134 192.168.80.135" -advanced exverify -confirm

The script is as follows:
sshUserSetup.sh (32.6 KB)
Keep answering yes, yes
Just press enter without any prompts
