Setting Up the Reverse Proxy

# cp -R /etc/nginx/sites-available/default /etc/nginx/sites-available/default.bak
# vim /etc/nginx/sites-available/default

Locate the following block:
…
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
…
Change the existing block to this:
…
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection ‘upgrade’;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
…

Save & quit

# systemctl reload nginx

You can now access the default Grafana login screen by pointing your web browser to server ip.

By default, every Grafana uses the same administrative login credentials, the USER and PASSWORD are admin.

Updating Credentials

Click on the small Grafana logo in the upper,hover over the admin button and click on the profile button

You may edit all your profile settings at here.

Disabling Grafana Registrations and Anonymous Access

vim /etc/grafana/grafana.ini

locate [users]
uncomment “;” infront the allow_sign_up and change “true” to “false” to disable others register on Grafana.
The code should be like this:
…
[users]
# disable user signup / registration
allow_sign_up = false
…

locate [auth.anonymous]
Setting enabled to true gives non-registered users access to your dashboards; setting this option to false limits dashboard access to registered users only.
…
[auth.anonymous]
# enable anonymous access
enabled = false
…

Save and exit.

systemctl restart grafana-server

At this point, Grafana is fully configured and ready for use.
