This shell script configures systemd services on a Linux system by copying service files to /etc/systemd/system and enabling them to start at boot time. It reloads the systemd daemon, enables and starts services for Jupyter Notebook and Selenium, ensuring they run automatically when the system boots up.

Run example

npm run import -- "install systemd"

install systemd

cd ~/jupytangular \
   && cp ./jupyter.service /etc/systemd/system \
   && cp ./jupyter.timer /etc/systemd/system \
   && systemctl daemon-reload \
   && systemctl enable jupyter.timer \
   && systemctl enable jupyter.service \
   && systemctl start jupyter.service \
   && systemctl start jupyter.timer \
   && cp ./selenium.service /etc/systemd/system \
   && systemctl daemon-reload \
   && systemctl enable selenium \
   && systemctl start selenium.service

#!/bin/bash

# Set the Jupyter and Selenium configuration directories
JUPYTER_DIR=~/jupytangular
SELENIUM_DIR=~/jupytangular

# Create the Jupyter and Selenium configuration directories if they do not exist
if [! -d "$JUPYTER_DIR" ]; then
  mkdir -p "$JUPYTER_DIR"
fi

# Copy configuration files to the system directory
cp./jupyter.service /etc/systemd/system
cp./jupyter.timer /etc/systemd/system
cp./selenium.service /etc/systemd/system

# Reload the systemd daemon to apply changes
systemctl daemon-reload

# Enable Jupyter and Selenium services
systemctl enable jupyter.timer
systemctl enable jupyter.service
systemctl enable selenium.service

# Start Jupyter and Selenium services
systemctl start jupyter.service
systemctl start jupyter.timer
systemctl start selenium.service

# TODO: Add error handling and logging for better debugging and monitoring

Systemd Configuration Script Breakdown

This is a shell script that configures systemd services on a Linux system. Here's a step-by-step explanation:

Directory and File Copying

1. cd ~/jupytangular: Changes the current working directory to ~/jupytangular.
2. cp./jupyter.service /etc/systemd/system: Copies the jupyter.service file from the current directory to /etc/systemd/system.
3. cp./jupyter.timer /etc/systemd/system: Copies the jupyter.timer file from the current directory to /etc/systemd/system.
4. cp./selenium.service /etc/systemd/system: Copies the selenium.service file from the current directory to /etc/systemd/system.

Systemd Configuration

1. systemctl daemon-reload: Reloads the systemd daemon to pick up changes to service files.
2. systemctl enable jupyter.timer and systemctl enable jupyter.service: Enables the jupyter.timer and jupyter.service services to start at boot time.
3. systemctl start jupyter.service and systemctl start jupyter.timer: Starts the jupyter.service and jupyter.timer services.
4. systemctl enable selenium and systemctl start selenium.service: Enables the selenium service to start at boot time and starts it.

These commands configure systemd to run Jupyter Notebook and Selenium services at boot time and start them immediately.
