Adding a Linux Service

    Creating Service
    Open a new service file in a text editor.
        sudo nano /etc/systemd/system/candle.service
    Sample contents of the file:
        [Unit]
        Description=Candle Test / Demo Server Built from Develop Branch

        [Service]
        WorkingDirectory=/var/aspnetcore/candle.cloud
        ExecStart=/var/aspnetcore/candle.cloud/Candle.WebApp --listen-url=http://192.168.0.24:5000
        Restart=always
        RestartSec=10  # Restart service after 10 seconds if dotnet service crashes
        SyslogIdentifier=candle-cloud
        User=www-data
        Environment=ASPNETCORE_ENVIRONMENT=Production
        Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

        [Install]
        WantedBy=multi-user.target

    Save the file and then enable the services.
        sudo systemctl enable candle.service

    Start the service and verify that it's running:
        sudo systemctl start candle.service
        sudo systemctl status candle.service

    Viewing logs
    Since the web app using Kestrel is managed using `systemd`, all events and processes are logged to a centralized journal. However, this journal includes all entries for all services and processes managed by `systemd`. To view the `candle.service`-specific items, use the following command:
        sudo journalctl -fu candle.service

    For further filtering, time options such as `--since today`, `--until 1 hour ago` or a combination of these can reduce the amount of entries returned.
        sudo journalctl -fu candle.service --since "2018-5-18" --until "2018-5-30 04:00"
