How can I change my environment if my nodes have different root passwords

How can I change my environment if my nodes have different root passwords?
And when I check the connection to other nodes, I naturally get this picture

root@ubuntu22:~/postgresql_cluster# ansible all -m ping 192.168.171.1 | SUCCESS => { "changed": false, "ping": "pong" } 192.168.171.3 | UNREACHABLE! => { "changed": false, "msg": "Data could not be sent to remote host \"192.168.171.3\". Make sure this host can be reached over ssh: ssh: connect to host 192.168.171.3 port 22: No route to host\r\n", "unreachable": true } 192.168.171.2 | UNREACHABLE! => { "changed": false, "msg": "Invalid/incorrect password: Warning: Permanently added '192.168.171.2' (ED25519) to the list of known hosts.\r\nPermission denied, please try again.", "unreachable": true }

In addition, having solved the problem of connecting to all nodes by issuing a key (although the original question remains open), I get this picture... PostgreSQL has not risen on any node

No. Because Ansible provides atomicity.
