Vim Edit SSH Configuration
vim /etc/ssh/sshd_ config
Find "# Port 22", directly type "yyp" in this line, copy this line to the next line, and then remove the comments in the two lines and change them to
Port 22 Port 10086
The default listening port of SSH is 22. If you do not force other ports to be specified, "Port 22" is an open 22 access port. I reserved port 22 above to prevent access to port 22 from becoming impossible due to various permissions and configuration problems. When everything is OK, close port 22.
Restart the server
shutdown -r now
