After creating a new user aps, perform password-free login. When performing ssh login, password-free login is still required. Later, I will find a solution to the problem on the Internet.
First we need to check the system log file

Found the problem: Authentication refused: bad ownership or modes for file
Literally, it can be seen that the owner and permissions of the directory are improperly configured. Looking for information, we know that: SSH does not want the home directory and the ~/.ssh directory to have write permissions for the group. Change it through the following commands
[aps@aps01 ~]$ chmod g-w /home/aps [aps@aps01 ~]$ chmod 700 /home/aps/.ssh [aps@aps01 ~]$ chmod 600 /home/aps/.ssh/authorized_keys
