For those unfamiliar, Systemd is a popular Init system used to start, run and manage multiple services and processes on Linux and other Unix-like operating systems.
Unlike a traditional init system, Systemd can control more than just process execution, it can manage and monitor system resources, log output, create networking rules, and more.
In this article, we show you how to create a custom Systemd service unit in Ubuntu.
There are two main types of service units: user and system services.
While user services are non-persistent and only available for the current session, system services are stored in a different directory, run on boot, and are available to all users.
You can easily create both types, and we show you how step-by-step, as well as showing you how to tweak your custom services.
