CentOS7启动SSH服务报:
Job for ssh.service failed because the control process exited with error codesee systemctl status ssh.service and journalctl -xe for details.
然后按照提示输入: systemctl status sshd.service

表示给出的提示很坑爹,完全不知道哪里出错了。
经过艰难的百度,可能是SELINUX启用了,并且SELINUX允许的sshd-port跟设置的port不匹配造成的.

1. 查看SeLinux设置的ssh端口
# semanage port -l | grep ssh

20180401224654690.
发现端口22222和22是允许被使用的
2.查看 ssh设置的端口
# vi /etc/ssh/sshd_config

ssh使用的是默认端口22,与selinux是匹配的。不是这个错。继续百度......
终于在ubuntu社区看到一篇帖子:
run sudo /usr/sbin/sshd -T to see what is wrong with the service and why does it fail.
# /usr/sbin/sshd -T

可以看到,似乎是sftp组的设置参数似乎有问题
# vi /etc/ssh/sshd_config

使用 : set number显示行号. 找到第147行

原来是ForceCommand 写错啦!赶紧改对.....
