| For security reasons, the default parameters are very strict. It is forbidden for root users to directly use ssh to log in . For example, use a non-root account first. After logging in to ssh, su becomes root. |

Waiting for PIDS: 349. Starting sshd. xxx# After the restart is complete, ssh can log in |
