【linux】在CentOS7上更改端口号时报错：Job for sshd.service failed because the control process exited with error

1、问题描述

在在CentOS7上更改端口号时报错：
Job for sshd.service failed because the control process exited with error code.See “systemctl status sshd.service” and “journalctl -xe” for details.

2、修改ssh端口号的方法

修改：$ sudo vi /etc/ssh/sshd_config

将 “#Port 22” 改为 “Port 11234”
将 “#PermitRootLogin yes” 改为 “PermitRootLogin no”

重启：sudo systemctl restart sshd.service
重启后报错

3、原因分析

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。

4、解决方法

使用semanage工具添加ssh端口号

sudo semanage port -a -t ssh_port_t -p tcp 11234

重启

sudo systemctl restart sshd.service
