I am using the server provided by the school and connecting to two servers through a jump server. The control machine is configured with passwordless SSH, but there are still SSH errors during the check, as shown in the picture.

How can I solve this? There is no problem when I use root on my own virtual machine.

You set up passwordless access for the tidb user, but not for root, right?

This prompt indicates that you didn’t provide a password when logging in as root. If it doesn’t work, try adding -p to the command you originally entered and then input the password to see if it works.

Manually SSH to see if it works. If not, add the -p parameter to deploy using a password.

Should the root user operate or the tidb user?
Both should establish mutual trust. If both are done, after the user logs in, test logging in with ssh username@ip.

You can go talk to the school and set up a course.

Try using a password first, without using passwordless authentication.

Many universities have offered courses.

Manually test if passwordless login is working: ssh root@ip hostname

Is passwordless authentication working properly, and are the users consistent?

| username: ffeenn | Original post link

Manually enter the password.

Try setting up passwordless access for root as well.

| username: ziptoam | Original post link

Password-free login, enabling root login in sshd, etc., all need to be checked.

Do you have a root account? Use root to install: -user root -p
