This post shows how to create Service unit files for systemd which let start and restart BuildBot on Linux distributions using systemd. This unit files depend on a working VirtualEnv installation of BuildBot in the /srv/buildbot directory. It also runs BuildBut with the user/group “buildbot”. Two unit files are necessary to start the master and slave instance respectively. Instead of using the buildbot/buildslave commands, the twistd binary is executed directly in foreground. twistd is an application/service framework for Python, which BuildBot makes use of.
