How to set up a remote Jupyter Notebook server on Ubuntu
January 27, 2019, 3 min read
In this tutorial we’ll learn how to install and configure a remote Jupyter Notebook server on Ubuntu. A typical use case for this is having a desktop computer with a powerful GPU that you want to expose to other machines, like a laptop or a Mac, when working with Jupyter Notebooks.
By default, a Jupyter Notebook server runs locally at 127.0.0.1:8888 and is accessible only from localhost on http://127.0.0.1:8888. We’re going to change that to allow remote connections. As a security precaution, I recommend blocking incoming internet connection to the
8888 port on your router.
In terminal, type:
jupyter notebook --generate-config
You will have to enter this password whenever you access your Notebooks from a browser. In terminal, type:
jupyter notebook password
You will see the following output:
Enter password: **** Verify password: **** [NotebookPasswordApp] Wrote hashed password to /home/your_username/.jupyter/jupyter_notebook_config.json
It’s a good idea to enable SSL when sharing your Jupyter Notebooks over the network. You’ll need a certificate for that. The easiest way is to create a self-signed certificate—the downside is that you’ll have to ignore your browser’s security warnings.
In terminal, type:
cd ~/.jupyter openssl req -x509 -nodes -days 9999 -newkey rsa:2048 -keyout mykey.key -out mycert.pem
The Jupyter Notebook config file
jupyter_notebook_config.py is in the
~/.jupyter directory. Open the file and change the following settings:
# Replace 'your_username' with your actual username c.NotebookApp.certfile = u'/home/your_username/.jupyter/mycert.pem' c.NotebookApp.keyfile = u'/home/your_username/.jupyter/mykey.key' # Allow remote connections c.NotebookApp.ip = '*' # Save Notebooks under your home folder. # Replace 'your_username' with your actual username c.NotebookApp.notebook_dir = '/home/your_username/notebooks/' # Do not open browser when Jupyter Notebooks start c.NotebookApp.open_browser = False
The last step is to ensure Jupyter Notebooks runs every time you boot Ubuntu. There are various ways you can achieve that. The easiest I’ve found is to add a cron job. In terminal, type
crontab -e to edit your cron jobs and add the following to the end of the file:
# Replace 'your_username' with your actual username @reboot cd ; source /.bashrc; ~/anaconda3/bin/jupyter notebook --config=/home/your_username/.jupyter/jupyter_notebook_config.py >>~/cronrun.log 2>&1
Congratulations! You can now use Jupyter Notebooks remotely and take advantage of your GPU. Remember to use
https when connecting to your Jupyter Notebook server (i.e.
