How to run another sshd on the same server?

Question

linux

Good afternoon,
There was a need to run another sftp installation on one RH server.
How to competently clone and run it on a different port without breaking the main sftp.
Different package versions on different ports.

Answer 1

vi /etc/ssh/sshd_config
port 22
port 2222
rc-service sshd reload

Answer 2

Take the sshd unit file, most likely it will be /lib/systemd/system/sshd.service
Copy it to, for example, /etc/systemd/system/sshd_new.service
In the resulting file, write the path to the new executable file, where it lies , and config (in which a different port must be specified), like this:
Save the file, then as root:

systemctl daemon-reload
systemctl enable sshd_new
systemctl start sshd_new

And everything is ready.
