I have a general question. How does one start a systemd unit *.service after a particular *.service has started successfully?
More specific question is, how do I start website.service only after mongodb.service has started? In other words website.service should depend on mongodb.service.
In the .service file under the [Unit] section:
[Unit]
Description=My Website
After=syslog.target network.target mongodb.service
The important part is the mongodb.service
The manpage describes it however due to formatting it's not as clear on first sight
