Setting Up Netdata with Basic Authentication on Nginx

To install Netdata, you can follow the detailed instructions available on DigitalOcean. Once you have Netdata set up, you will need to secure access to its dashboard using basic authentication.

During the setup, you will create a user-password file using the htpasswd command. This file will contain hashed credentials, which look something like this:

username:$apr1$somehashedvalue

Next, you will need to configure your Nginx server block to enforce authentication. Here’s an example configuration:

server {
    listen your_server_ip:80;
    server_name example.com;

    auth_basic "Authentication Required";
    auth_basic_user_file /path/to/netdata-access;
}

In this configuration, netdata-access is the file containing your hashed credentials, located in the Nginx configuration directory. However, since this server block listens on port 80 (HTTP), you might be wondering whether your password is transmitted in plaintext when you access the dashboard.

Unfortunately, without SSL (which would typically run on port 443), the credentials are sent unencrypted over the network. To secure your connection, consider setting up SSL for your Nginx server. This will encrypt the data transmitted between the client and server, including your password.

For more information on securing your Nginx server with SSL, refer to the official Nginx documentation.
