Step 1: Create a VPS Instance on Shape.Host
To begin, create a virtual private server (VPS) using Shape.Host:
Visit https://shape.host and log into your account.
Click on “Create” in the dashboard menu.
Select “Instance” as the resource type.
Pick the closest server location to your target audience (e.g., Frankfurt, Dallas, Amsterdam).
Choose Debian 12 (64-bit) as the operating system.
Select a hosting plan with at least 2 CPUs, 4 GB RAM, and 20 GB SSD for good performance.
Click “Create Instance”.
Once provisioned, copy the IP address from the “Resources” section of your dashboard.
Step 2: Connect to Your VPS Instance
From Linux or macOS:
Open a terminal and connect via SSH using:
ssh root@your-server-ip
From Windows:
Use an SSH client like PuTTY:
- Enter your server’s IP address.
- Choose SSH as the connection type.
- Click Open to start the session.
Step 3: Install JupyterLab on Debian 12
Update the system package index:
apt update
This command updates the list of available packages and their versions.
Install Python, pip, venv, and Git:
apt install python3 python3-pip python3-venv git
These are essential packages for Python development and virtual environments.
Create a project directory for JupyterLab:
mkdir -p /opt/jupyterlab
This creates a dedicated folder where JupyterLab will be installed.
Navigate into the project directory:
cd /opt/jupyterlab
Create a virtual Python environment:
python3 -m venv venv
This sets up an isolated environment so JupyterLab dependencies won’t affect system-wide packages.
Activate the virtual environment:
source venv/bin/activate
Upgrade pip:
pip install --upgrade pip
Keeps pip up to date with the latest version.
Install JupyterLab:
pip install jupyterlab
This command installs the full JupyterLab application inside the virtual environment.
Step 4: Create a Systemd Service for JupyterLab
Create the service file:
nano /etc/systemd/system/jupyterlab.service
Paste the following content:
[Unit]
Description=JupyterLab
After=network.target
[Service]
Type=simple
User=root
WorkingDirectory=/opt/jupyterlab
ExecStart=/opt/jupyterlab/venv/bin/jupyter lab --allow-root --ip=0.0.0.0 --port=8888 --no-browser
Restart=always
[Install]
WantedBy=multi-user.target
This service configuration allows JupyterLab to run in the background and automatically start on boot.
Apply and enable the new service:
systemctl daemon-reexec
Reloads the system manager configuration.
systemctl daemon-reload
Detects new or modified unit files.
systemctl enable jupyterlab
Enables the JupyterLab service to start at boot.
systemctl start jupyterlab
Starts the service immediately.
systemctl status jupyterlab
