Reverse Proxy Grafana with Nginx
Video Lecture
Description
Now to add a proxy. I will use Nginx. The Nginx proxy will also allow us to more easily configure our Grafana servers public address and bind an SSL certificate to it. It is possible to change the grafana.ini settings to use a specific port number, SSL certificates and HTTP protocol instead, but you will also need to manage file permissions that the Grafana server process will need. It is more versatile to use a dedicated proxy and especially if your server will be hosting multiple web applications.
Check if Nginx is installed
nginx -v
No, then install it with
sudo apt install nginx
Now check its version
nginx -v
Now check its status
sudo service nginx status
Visit http://[your ip address]
You should get the default Nginx web server index.html.
CD to the Nginx sites-enabled folder
cd /etc/nginx/sites-enabled
Create a new Nginx configuration for Grafana
sudo nano YOUR-DOMAIN-NAME.conf
And copy/paste the example below, changing YOUR-DOMAIN-NAME to your actual domain name you've set up. Mine was grafana.sbcode.net.
server {
listen 80;
listen [::]:80;
server_name YOUR-DOMAIN-NAME;
location / {
proxy_set_header Host $http_host;
proxy_pass http://localhost:3000/;
}
}
Save and restart Nginx
sudo service nginx restart
sudo service nginx status
Test it by visiting again
http://YOUR-DOMAIN-NAME
Visiting your IP address directly will still show the default Nginx welcome page. If you don't want this to happen, then you can delete its configuration using the command below.
rm /etc/nginx/sites-enabled/default
Grafana 9 and Ubuntu 22.04 Notes
Proxy Set Header
In later versions of Grafana 8 and version 9, the nginx configuration requires the extra line setting the proxy header for the location node.
I.e.,
server {
listen 80;
listen [::]:80;
server_name YOUR-DOMAIN-NAME;
location / {
proxy_set_header Host $http_host;
proxy_pass http://localhost:3000/;
}
}
Daemons using outdated libraries
Since Ubuntu 22.04, installing new packages may give you a full screen prompt to restart other dependent services. Press Tab to highlight the OK option, and press Enter.
