kea dhcp systemd service files for single instance

This systemd service files can be used to launch a single kea instance on a server.

This requires that the config files are located under /etc/kea/ and the config files themself match this pattern:

  • dhcp4 server: kea-dhcp6.conf
  • dhcp6 server: kea-dhcp4.conf
  • ddns server: kea-ddns.conf
  • ctrl agent: kea-ctrl-agent.conf

You can name them differently but then have to adjust the service files accordingly

The service files can used by copying them to the systemd service directory (eg. on debian /lib/systemd/system/ /etc/systemd/system/). Then enable the different kea services by running:

  • dhcp4 server: systemctl enable kea-dhcp4-server
  • dhcp6 server: systemctl enable kea-dhcp6-server
  • ddns server: systemctl enable kea-ddns-server
  • ctrl agent: systemctl enable kea-ctrl-agent

If you want that the kea services automatically restart if they crash you can add Restart=always to the [Service] section of the service files

See for a version with multiple instances on a single server
