Start Jupyter as service

From https://gist.github.com/whophil/5a2eab328d2f8c16bb31c9ceaf23164f

/etc/systemd/system/jupyter.service:

# After Ubuntu 16.04, Systemd becomes the default.
# It is simpler than https://gist.github.com/Doowon/38910829898a6624ce4ed554f082c4dd

[Unit]
Description=Jupyter Notebook

[Service]
Type=simple
PIDFile=/run/jupyter.pid
ExecStart=jupyter-notebook --config=/home/pi/.jupyter/jupyter_notebook_config.py
User=pi
Group=pi
WorkingDirectory=/home/pi/Notebooks/
Restart=always
RestartSec=10
#KillMode=mixed

[Install]
WantedBy=multi-user.target

To use, just do it in systemctl way:

sudo systemctl start jupyter
sudo systemctl stop jupyter
# To launch while start up
sudo systemctl enable jupyter

❕ NOTICE

run systemctl daemon-reload often when changing unit file. Or it will silently use the old bad file.

不要问我是怎么知道的

libf77blas.so.3: cannot open shared object file

sudo apt install libatlas-base-dev

Config Jupyter

Follow https://jupyter-notebook.readthedocs.io/en/stable/public_server.html

Typical Way

jupyter notebook --generate-config
# Get passwd hash
python3 -c 'from notebook.auth import passwd;print(passwd())'
# cd to a nice directory
# where `nodes` means `no-des`, no passwd for private key
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -sha256 -nodes

And here is the official example for the configuration file:

# Set options for certfile, ip, password, and toggle off
# browser auto-opening
c.NotebookApp.certfile = '/absolute/path/to/your/certificate/fullchain.pem'
c.NotebookApp.keyfile = '/absolute/path/to/your/certificate/privkey.pem'
# Set ip to '*' to bind on all interfaces (ips) for the public server
c.NotebookApp.ip = '*'
c.NotebookApp.password = 'sha1:bcd259ccf...<your hashed password here>'
c.NotebookApp.open_browser = False
# It is a good idea to set a known, fixed port for server access
c.NotebookApp.port = 9999

⚠️ ​IMPORTANT

There are so many keys in the file, be sure to modify the correct key.

Listen to ipv6 Only

c.NotebookApp.ip = '::'

Jupyter Themes

Installation

pip3 install jupyterthemes

Configuration

jt -t oceans16 -T -N -fs 16 -nfs 16 -cellw 90%

Explanation:

-T, --toolbar         make toolbar visible
-N, --nbname          nb name/logo visible
-t THEME              theme name to install
-fs MONOSIZE          code font-size
-nfs NBFONTSIZE       notebook fontsize
-tfs TCFONTSIZE       txtcell fontsize
-dfs DFFONTSIZE       pandas dataframe fontsize
-ofs OUTFONTSIZE      output area fontsize
-mathfs MATHFONTSIZE  mathjax fontsize (in %)
-cellw CELLWIDTH      set cell width (px or %)

Font sizes are in pt

Behind Nginx

Reference: https://gist.github.com/christopherbaek/39e6c432e212ca7a67ffe015fe869664

• Disable SSL and bind IP back to localhost, add base_url

c.NotebookApp.base_url = 'jupyter'
c.NotebookApp.ip = '127.0.0.1'
c.NotebookApp.open_browser = False
c.NotebookApp.password = 'sha1:84cb...36f7e6'
c.NotebookApp.port = 9999

• Config Nginx, headers are important, slash is also important

location /jupyter/ {
    proxy_pass http://127.0.0.1:9999/jupyter/;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-NginX-Proxy true;

    # WebSocket support
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Origin "";
}
