Awesome your Grafana server is now up and running.[/vc_column_text][vc_column_text]6. Allow or open the Grafana services on port 3000 via TCP on your server, by adding new firewall rules
Grafana uses the port 3000 for Web Administration so we can access the grafana on local network.

To open the port 3000 on CentOS 8, run this command
[simterm]
$ sudo firewall-cmd –add-port=3000/tcp –permanent
success
[/simterm]
[simterm]
$ sudo firewall-cmd –reload
success
[/simterm]

Verify the firewall configuration is correctly set.
[simterm]
$ sudo firewall-cmd –list-all | grep ports
ports: 3000/tcp
forward-ports:
source-ports:
[/simterm]
[/vc_column_text][vc_column_text]7. Launch Grafana Web UI, navigate to http://localhost:3000 or the http://server-ip:3000 with your web browser withe port 3000,the default port for Grafana is 3000.

Note:
The default login for Grafana is ‘admin’ and the default password is also ‘admin’ and after you login the grafana dashboard asked you to update your password.
Change Password Before you can get started with awesome dashboards we need you to make your account more secure by changing your password. You can change your password again later.

You should be able to see the default dashboard on Grafana.

[/vc_column_text][vc_column_text]8. Disable new user registrations in order to prevent other user to register and access your grafana serverm you can disable user registration.
Note:
User registration can be access at http://localhost:3000/signup / http://server-ip:3000/signup

[/vc_column_text][vc_column_text]To disable user registration, head back to your configuration file, and disable the following section.
[simterm]
$ sudo nano /etc/grafana/grafana.ini

[users]
# disable user signup / registration
;allow_sign_up = true

# Allow non admin users to create organizations
;allow_org_create = true

# Set to true to automatically assign new users to the default organization (id 1)
;auto_assign_org = true
[/simterm]

Change the allow_sign_up setting to false, and restart your Grafana server.
[simterm]
;allow_sign_up = false
[/simterm]
[simterm]
$ sudo systemctl restart grafana-server
[/simter]
