Configured SSH mutual trust, but during cluster check, detecting self failed while other IPs are done.

TiUP needs to be deployed on a separate control machine and cannot be mixed with other nodes.

You also need to copy a public key for yourself.

When I tried to use tiup cluster -user -p to deploy, I found that I could only enter one password. However, I have multiple machines with multiple passwords. How should I solve this?

Create a new user, using the same account is fine.

Just configure mutual trust for your own IP in SSH.

  1. The control machine can also be deployed on the host where the DB instance is located. Although it is not recommended, it is technically feasible.
  2. Even if it is on the same host, you still need to configure SSH for this host.
  3. You can transfer the control machine’s key to each DB host. A relatively simple method is to use:
    ssh-copy-id -i ~/.ssh/id_rsa.pub ${IP}
    where ${IP} is the specific DB host IP address.
