[NGINX](https://www.nginx.com) is a high performance load balancer, web server, and reverse proxy.
- In your NGINX configuration file inside `http` section, add the following:
```nginx
# this is required to proxy Grafana Live WebSocket connections.
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
upstream grafana {
server localhost:3000;
}
server {
listen 80;
root /usr/share/nginx/html;
index index.html index.htm;
location / {
proxy_set_header Host $http_host;
proxy_pass http://grafana;
}
# Proxy Grafana Live WebSocket connections.
location /api/live/ {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_set_header Host $http_host;
proxy_pass http://grafana;
}
}
```
- Reload the NGINX configuration.
- Navigate to port 80 on the machine NGINX is running on. You're greeted by the Grafana login page.
For Grafana Live which uses WebSocket connections you may have to raise Nginx [worker_connections](https://nginx.org/en/docs/ngx_core_module.html#worker_connections) option which is 512 by default – which limits the number of possible concurrent connections with Grafana Live.
Also, be aware that the above configuration will work only when the `proxy_pass` value for `location /` is a literal string. If you are using a variable here, [read this GitHub issue](https://github.com/grafana/grafana/issues/18299). You will need to add [an appropriate NGINX rewrite rule](https://www.nginx.com/blog/creating-nginx-rewrite-rules/).
To configure NGINX to serve Grafana under a _sub path_, update the `location` block:
```nginx
# this is required to proxy Grafana Live WebSocket connections.
