GitHub - jupyterhub/jupyterhub: Multi-user server for Jupyter notebooksをインストールして、マルチユーザ対応。

JupyterHub
With JupyterHub you can create a multi-user Hub which spawns, manages, and proxies multiple instances of the single-user Jupyter notebook (IPython notebook) server.
JupyterHub provides single-user notebook servers to many users. For example, JupyterHub could serve notebooks to a class of students, a corporate workgroup, or a science research group.
JupyterHubを使用すると、シングルユーザーJupyterノートブック（IPythonノート）サーバーの複数のインスタンスをスポーン、管理、プロクシするマルチユーザハブを作成することができます。JupyterHubは、多くのユーザーにシングル・ユーザ・ノートブック・サーバを提供します。例えば、JupyterHubは学生のクラス、企業のワークグループ、または科学研究グループに（Jupyter)notebookを提供することができます。だそうです. (↑グーグル翻訳改)

systemdで自動起動
-
sudo vi /lib/systemd/system/jupyterhub.service/lib/systemd/system/jupyterhub.service[Unit] Description=Jupyterhub [Service] User=jupyterhub ExecStart=/usr/local/bin/jupyterhub WorkingDirectory=/etc/jupyterhub [Install] WantedBy=multi-user.target -
サービス有効・開始・状態
sudo systemctl enable jupyterhub sudo systemctl start jupyterhub sudo systemctl status jupyterhub
その他
-
c.JupyterHub.confirm_no_ssl = Trueで--no-sslにしてますが、ググるとすぐでてきて、簡単に対応できたと思います。(一度、動作確認してますが、ローカルネットワークならいらないかと...説明が面倒...)
