Create a Services in linux box

In linux box, everything runs at startup is a service.

Service located on  /etc/systemd/system/servicename.service

Step to create a service are :
1. Create a service user account
2. Change ownership of config file to the service account
3. Create a service file to load when startup

Create service user account the secure way :

• $ sudo useradd --no-create-home --shell /bin/false blackbox_exporter

Here are template for create a service and use the created user above.

[Unit]
Description=Blackbox Exporter
Wants=network-online.target
After=network-online.target

[Service]
User=blackbox_exporter
Group=blackbox_exporter
Type=simple
ExecStart=/usr/local/bin/blackbox_exporter --config.file /etc/blackbox_exporter/blackbox.yml

[Install]
WantedBy=multi-user.target

This will be inside the .service file.

Then we need to reload the daemon.

#systemctl daemon-reload

And service can run using below command :

#systemctl start service_name

To enable it do :

#systemctl enable service_name

Hope this helps
