查找出现的错误原因
根据错误提示运行
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | systemctl status ssh.service #提示为 ● ssh.service - OpenBSD Secure Shell server Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset: > Active: failed (Result: exit-code) since Sat 2020-12-12 10:50:04 CST; 1mi> Docs: man:sshd(8) man:sshd_config(5) Process: 11657 ExecStartPre=/usr/sbin/sshd -t (code=exited, status=255/EXC> 12月 12 10:50:04 li-virtual-machine systemd[1]: ssh.service: Scheduled restart> 12月 12 10:50:04 li-virtual-machine systemd[1]: Stopped OpenBSD Secure Shell s> 12月 12 10:50:04 li-virtual-machine systemd[1]: ssh.service: Start request rep> 12月 12 10:50:04 li-virtual-machine systemd[1]: ssh.service: Failed with resul> 12月 12 10:50:04 li-virtual-machine systemd[1]: Failed to start OpenBSD Secure> |
如图所示
之后执行上图所示的ExecStartPre=/usr/sbin/sshd -t
1 2 3 4 5 6 7 8 | /usr/sbin/sshd -T 提示/etc/ssh/sshd_config中61行 64 66 68行出现错误 /etc/ssh/sshd_config: line 61: Bad configuration option: rootRootLogin /etc/ssh/sshd_config: line 64: Bad configuration option: sudo /etc/ssh/sshd_config: line 66: Bad configuration option: systemctl /etc/ssh/sshd_config: line 68: Bad configuration option: m /etc/ssh/sshd_config: terminating, 4 bad configuration options |
解决办法
1 2 3 4 5 6 | vi /etc/ssh/sshd_config #61行rootRootLogin拼错 PermitRootLogin #64 66 68 行可以注释掉 #重启 service sshd restart |
