Connect the SSH client to the host and run the script in the nohup background.

The following script is implemented: first copy the script from the local host to the remote host, and then connect to the remote host using SSH to execute the copied script (because the script needs to be executed for a long time, it should be executed in the background ), this script is only used for memo. If you have any questions, please kindly advise!
