Step 3: Start Grafana Service

Grafana service is managed by systemd. Start the service and enable it to start on boot.

$ sudo systemctl enable --now grafana-server.service 
 Synchronizing state of grafana-server.service with SysV service script with /usr/lib/systemd/systemd-sysv-install.
 Executing: /usr/lib/systemd/systemd-sysv-install enable grafana-server
 Created symlink /etc/systemd/system/multi-user.target.wants/grafana-server.service → /usr/lib/systemd/system/grafana-server.service.

The default port used is 3000. If you have another process using this port, you’ll need to set custom port in Grafana configuration file /etc/grafana/grafana.ini.

http_port = 3000

Your grafana-server service should show running state.

$ systemctl status grafana-server.service
