One of the main advantages of Netdata is that we can install it using the official Ubuntu repositories. This, apart from being secure, will give us the necessary stability in this kind of procedure.

So, open a terminal or SSH session.

When you start it, it updates Ubuntu completely.

sudo apt update
sudo apt upgrade

Once the system is fully upgraded, you can install Netdata by running the following command:

sudo apt install netdata

Netdata is also managed as a system service, so you can use the systemctl command to start it, stop it, or check its status.

Netdata is now available from http://localhost:19999 but you may want to configure Nginx as a reverse proxy.

Configuring Nginx as reverse proxy for Netdata

First, install Nginx from the Ubuntu repositories.

sudo apt install nginx

Next, create a new configuration file for Netdata

sudo nano /etc/nginx/conf.d/netdata.conf

And add the following:

upstream backend {
# the Netdata server
server 127.0.0.1:19999;
keepalive 64;
}
server {
# nginx listens to this
listen 80;
# the virtual host name of this
server_name angtest.ga;

    location / {
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://backend;
proxy_http_version 1.1;   
proxy_pass_request_headers on;
proxy_set_header Connection "keep-alive";
proxy_store off;
}
}

Replace server_name with the name of your server.

It is also a good idea to secure your Netdata installation by installing and adding certificates to enable HTTPS.

So, install Certbot.
sudo apt install certbot python3-certbot-nginx

And create the new certificate for your domain by running:

sudo certbot --nginx --agree-tos --redirect --hsts --staple-ocsp --email [email protected] -d your-domain

Replace the email and -d values with your own.

Finally, restart Nginx.

sudo systemctl restart nginx

Using Netdata

Now you can open netdata from your web browser by opening https://your-domain and you will see the dashboard.

  1. Hello. I Have this problem:

    sudo certbot –nginx –agree-tos –redirect –hsts –staple-ocsp –email [email protected] -d Netdata
    Saving debug log to /var/log/letsencrypt/letsencrypt.log
    Error while running nginx -c /etc/nginx/nginx.conf -t.

    nginx: [emerg] invalid parameter “server_name” in /etc/nginx/conf.d/netdata.conf:12
    nginx: configuration file /etc/nginx/nginx.conf test failed

    The nginx plugin is not working; there may be problems with your existing configuration.
    The error was: MisconfigurationError(‘Error while running nginx -c /etc/nginx/nginx.conf -t.\n\nnginx: [emerg] invalid parameter “server_name” in /etc/nginx/conf.d/netdata.conf:12\nnginx: configuration file /etc/nginx/nginx.conf test failed\n’)

    My netdata.conf:

    upstream backend {
    # the Netdata server
    server 127.0.0.1:12999;
    keepalive 64;
    }

    server {
    # nginx listens to this
    listen 80

    # the virtual host name of this
    server_name C4.netfree;

    location / {
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://backend;
    proxy_http_version 1.1;
    proxy_pass_request_headers on;
    proxy_set_header Connection “keep-alive”;
    proxy_store off;
    }
    }
