如何修改ssh默认端口
修改的是 /etc/ssh/sshd_config 文件

1. [root@linux ~]# vi /etc/ssh/sshd_config
2. # $OpenBSD: sshd_config,v 1.100 2016/08/15 12:32:04 naddy Exp $
4. # This is the sshd server system-wide configuration file. See
5. # sshd_config(5) for more information.
7. # This sshd was compiled with PATH=/usr/local/bin:/usr/bin
9. # The strategy used for options in the default sshd_config shipped with
10. # OpenSSH is to specify options with their default value where
11. # possible, but leave them commented. Uncommented options override the
12. # default value.
14. # If you want to change the port on a SELinux system, you have to tell
15. # SELinux about this change.
16. # semanage port -a -t ssh_port_t -p tcp #PORTNUMBER
17. #
18. Port 10008 //默认是有 # 号的，而且默认是 22 ，修改一下就ok了
19. #AddressFamily any
20. #ListenAddress 0.0.0.0
21. #ListenAddress ::

重起ssh服务，修改端口才生效

1. [root@linux ~]# service sshd restart
2. Stopping sshd: [ OK ]
3. Starting sshd: [ OK ]
4. [root@linux ~]#

注意修改端口，记得添加防火墙

1. [root@linux ~]# firewall-cmd --zone=public --add-port=10008/tcp --permanent
2. [root@linux ~]# firewall-cmd --reload
