permissions. for the production environment, root account protection is very important, one of which is that during remote SSH connection, we 'd better disable the root remote connection function. You need to modify the configuration file. There is an sshd_config file under/etc/ssh. This file contains a PermitRootLogin configuration, which is commented out by # by default. to disable SSH login, you need to remove this comment, change the value to no (the default value is yes ).Copy codeThe code

The Troubleshooting logic will naturally fall into the ssh-related settings of the server. 1. Check whether the sshd server is started. If it is started properly, exclude 2. Check
