Serving Grafana on a port < 1024

If you are using systemd and want to start Grafana on a port that is lower than 1024, you must add a systemd unit override.

1. Run the following command to create an override file in your configured editor.

   bashCopy

   # Alternatively, create a file in /etc/systemd/system/grafana-server.service.d/override.conf
   sudo systemctl edit grafana-server.service
   

2. Add the following additional settings to grant the CAP_NET_BIND_SERVICE capability.

   To learn more about capabilities, refer to capabilities(7) — Linux manual page.

   iniCopy

   [Service]
   # Give the CAP_NET_BIND_SERVICE capability
   CapabilityBoundingSet=CAP_NET_BIND_SERVICE
   AmbientCapabilities=CAP_NET_BIND_SERVICE
   
   # A private user cannot have process capabilities on the host's user
   # namespace and thus CAP_NET_BIND_SERVICE has no effect.
   PrivateUsers=false
