Centos7 modifies that the default login port of ssh is similar to that of centos6, except that the firewall is different, and then it is best to turn off selinux.

[modify ssh default port 22]

Vi / etc/ssh/sshd_config

Add a line under Port 22, taking port 50000 as an example, Port 50000

Then save and restart the ssh service systemctl restart sshd.service

[release new ports in the firewall]

Firewall-cmd-permanent-add-port=50000/tcp

Use this command to query

Firewall-cmd-permanent-query-port=50000/tcp

If it is yes, it is successful. If it is no, it is not successful.

Reload firewall firewall-cmd-reload after success

[close selinux]

Check the selinux status sestatus. If it is enabled, it is enabled.

Vi / etc/selinux/config

Modify SELINUX=disabled

Then restart vps and try to log in with the new port 50000. If the login is successful, vi / etc/ssh/sshd_config delete Port port 22, and then restart the ssh service.
