LogBucket
a simple web service to keep important logs in mongodb
For recent versions of Ubuntu create /etc/systemd/system/myservice.service with:
[Unit]
Description=my amazing service
[Service]
Restart=always
RestartSec=3
ExecStart=/usr/bin/path/to/my/service some args
[Install]
WantedBy=multi-user.target
Run this one time:
systemctl enable myservice
You can then start and stop your service with:
sudo systemctl start myservice
sudo systemctl stop myservice
It will also start automatically when the server boots, and restart if it crashes.

There are many other service management solutions, but systemd comes with Ubuntu 16 so it's probably the easiest to use.
