After the installation of Grafana 7 on CentOS 7, the service can be started and enabled to start on system start using systemctl service management command:

sudo systemctl enable --now grafana-server

The service should be in running state.

$ systemctl status  grafana-server
  ● grafana-server.service - Grafana instance
    Loaded: loaded (/usr/lib/systemd/system/grafana-server.service; enabled; vendor preset: disabled)
    Active: active (running) since Tue 2019-06-04 11:19:36 UTC; 5min ago

Step 3: Configure Firewall

If you have an active firewalld service, ensure port 3000 is allowed.

sudo firewall-cmd --add-port=3000/tcp --permanent
sudo firewall-cmd --reload

Confirm the port is allowed in the firewalld.

$ firewall-cmd --list-all | grep 3000
ports: 3000/tcp
