There may be many Linux hosts in the list of managed servers, and then they visit each other and do a lot of things to interact with each other. It would be too troublesome if they all use passwords to access each other. Let's share with you how to establish a ssh trust relationship between two Linux hosts.

1. Use the command to create the key on host A first.

2. At this point, we can see the created public and private key in the / root/.ssh/ directory: ls / root/.ssh/

3. Let's copy the id_rsa.pub file to host B: scp-r / root/.ssh/id_rsa.pub 192.168.31.147:/root/.ssh/authorized_keys

4. At this point, you can see that host A connects to host B without entering a password.

5. Similarly: we create a public and private key on host B, and then put the public key file into the / root/.ssh/authorized_keys file of host A. Then host B connects to host A without having to enter a password.

6. As you can see above, as long as you create a public or private key and put your own public key in the other party's / root/.ssh/authorized_keys file, you can connect to the other party's host without a password. As long as you understand this principle, it will be easy.
