This series gives practical examples of and teaches the theory behind making your applications run like services. It explores the init systems of System V, Upstart, and systemd from the perspective of service startup.
This tutorial shows you how to configure system services to automatically restart after a crash or a server reboot. We cover the three most common init systems in this tutorial: System V, Upstart, and systemd.
In this second tutorial about starting Linux services automatically, we’ll take a step back and explain init processes in more detail. You should gain a good understanding of how they control a daemon’s start-up behavior. We’ll see how to do this from three different init systems: System V, Upstart, and systemd.
