Script to run jupyter notebooks from remote server

问题

I have a server (Ubuntu server 16.04) that runs jupyter notebooks, and a local machine (Mac) where I use google-chrome to visualize these notebooks. To do so, I have to:

Run jupyter notebook in the server:

jupyter notebook --no-browser --port=${remotePort}
Specify a SHH tunnel in my local machine:

ssh -f ${username}@${serverIP} -L ${localPort}:localhost:${remotePort}

To automate this process, I've created the script jupyter.sh (described below), such that I only run on my local machine:

bash jupyter.sh -u myUserNameInServer

It works flawlessly. It's able to run the previous two steps plus it automatically open the jupyter page in my web-browser. Still, I would like to know if there is a better way to do this. I would greatly appreciate your comments.

Thanks in advance.

回答1:

You can use the "jupyter config file" wich is not activated by default so need to do this command fisrt (on your server):

jupyter notebook --generate-config

Then in the generated "jupyter_notebook_config.py" in the "/.jupyter" folder : uncomment the line and change the value.

This way you can tweak configuation such as password instead of token, default directory , port and so on .. Do as you want it may be a proper way to do some of the "jupyter config" in your script then keep evertything else.
