Custom Service Management

This course uses creating a JupyterLab service that starts automatically on boot as an example. This is for reference only regarding service management procedures. Actual factory images already have the JupyterLab service configured to start automatically on boot.

1. Creating a Service File

Create a file named jupyterlab.service in your user directory.

xxxxxxxxxx
touch jupyterlab.service
vim jupyterlab.service

Add the following content: User represents the username and needs to be modified according to your actual username; ExecStart represents the command to be executed and needs to be modified according to your actual command.

System service file:

xxxxxxxxxx
[Unit]
Description=jupyterlab service
After=network.target
​
[Service]
Type=simple
ExecStart=/usr/local/bin/jupyter-lab
config=/home/jetson/.jupyter/jupyter_lab_config.py --no-browser
User=jetson
Group=jetson
WorkingDirectory=/home/jetson/
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target
​

Then press Esc to exit editing, type :wq to save and exit the file.

2. Update Services

Copy the newly created jupyterlab.service service file to the /etc/systemd/system/ path.

xxxxxxxxxx
sudo cp jupyterlab.service /etc/systemd/system/

Update system service

xxxxxxxxxx
sudo systemctl daemon-reload

3. Managing services

Check service status

xxxxxxxxxx
sudo systemctl status jupyterlab.service

Start service

xxxxxxxxxx
sudo systemctl start jupyterlab.service

Restart service

xxxxxxxxxx
sudo systemctl restart jupyterlab.service

Set service to start automatically on boot

xxxxxxxxxx
sudo systemctl enable jupyterlab.service

Stop service

xxxxxxxxxx
sudo systemctl stop jupyterlab.service

Disable service from starting on boot

xxxxxxxxxx
sudo systemctl disable jupyterlab.service
