A simple way to launch Jupyter Notebook / Lab and set a password

Introduction

Qiita has already mentioned how to set a password for Jupyter, but I wish it was simply written as "There is no doubt if you do it this way. It's easy and secure." I hope it will be helpful for those who set up a Jupyter Notebook server from scratch.

For the time being, from the installation of Jupyter server.

Premise

--Availability of pip

Launch the Jupyter Notebook server

terminal

$ pip install jupyter
$ jupyter notebook --port=8888 #If you want to specify the port

Launch Jupyter Lab server

terminal

$ pip install jupyterlab
$ jupyter labextension install jupyterlab-plotly #When using Plotly with Jupyter Lab (details will be described later)
$ jupyter lab --port=8888 #If you want to specify the port

Set password

You don't have to hash it yourself or write the password in clear text, it will be automatically encrypted and saved by keyboard input. It's easy. See also: Official Documentation

terminal

$ jupyter notebook password
Enter password: 
Verify password:
[NotebookPasswordApp] Wrote hashed password to $HOME/.jupyter/jupyter_notebook_config.json

Digression

Generate a configuration file

If you don't want to launch the browser when the server starts, you can edit this file directly. The method is common to Jupyter Notebook / Lab.

terminal

$ jupyter notebook --generate-config
Writing default config to: $HOME/.jupyter/jupyter_notebook_config.py

#actually$HOME is not displayed. The home directory of your environment is displayed.

Required settings if using Plotly with Jupyter Lab

When I try to draw a Plotly graph in Jupyter Lab, it may not be displayed. Let's install the plugin with the jupyter command. It is assumed that the node command can be used globally.

Install as described in * JupyterLab Support (Python 3.5+) * in Plotly Official Documentation.

terminal

$ brew install node #For macOS
$ node --version
v14.13.0
$ jupyter labextension install jupyterlab-plotly
