Persistent use of Jupyter Notebook from remote ser

问题:

I connect to a remote server using ssh -L but if I close the laptop lid or the connection is lost, the jupyter notebook is disconnected.

After I reconnect to the remote server, the "last" session is lost.

What can be done to make it persistent? Could screen help with it?

回答1:

On the remote server, you should open your jupyter in a screen session, it will make it persistent if you lose the connection to the server and resume it.

1. On your computer: ssh -L xxxx:localhost:yyyy server.
2. screen.
3. jupyter notebook --no-browser --port=yyyy.
4. In your browser: localhost:xxxx.

To disconnect manually and reconnect:

1. Exit the screen window: control + a and then d.
2. Disconnect from the server: control + d
3. And reconnect ssh -L xxxx:localhost:yyyy.
4. Optionally, you can reopen the screen window, though unnecessary, using screen -r.
5. Go back to your notebook or reopen localhost:xxxx.

The standard usage for persisting Jupyter server sessions is the use of nohup and &; in your remote server with IP address xx.xx.xx.xx:

nohup jupyter notebook --no-browser --ip xx.xx.xx.xx --port yyyy &

Now, even if you switch off your laptop or lose the connection, you will be always able to reconnect by pointing your browser at xx.xx.xx.xx:yyyy
