Step 2: Start Grafana 6 service on CentOS 7

After the installation of Grafana 6 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
      Docs: http://docs.grafana.org
  Main PID: 25423 (grafana-server)
    CGroup: /system.slice/grafana-server.service
            └─25423 /usr/sbin/grafana-server --config=/etc/grafana/grafana.ini --pidfile=/var/run/grafana/grafana-server.pid --packaging=rpm cfg:…

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

Step 4: Access Grafana Dashboard

Once the service has been started, you can access its web dashboard by visiting http://[serverip|hostname]:3000.

The default login details are:

Username: admin
Password: admin

You’re asked to reset admin password after successful login. Provide a new password and confirm.
