fedora 32更改端口号重启sshd服务时报错：Job for sshd.service failed because the control process exited with error
 
在fedora上更改端口号重启sshd服务时报错：
Job for sshd.service failed because the control process exited with error code.See “systemctl status sshd.service” and “journalctl -xe” for details.

重启：sudo systemctl restart sshd
重启后报错

原因:
查看SElinux允许的ssh的端口号
$ sudo semanage port -l | grep ssh
ssh_port_t                     tcp      22
发现SELinux允许的ssh的端口号和ssh配置文件中设置的端口号不一致。

解决方法:
使用semanage添加ssh端口号
sudo semanage port -a -t ssh_port_t -p tcp 11234
sudo systemctl restart sshd
成功！！！！
