How to set up nginx whitelist

In nginx, whitelisting is an access control mechanism used to restrict access to specific parts of a website or application, allowing only requests from authorized sources. The following steps illustrate how to set up nginx whitelist:

1. Determine the allowed IP address or domain name

First, determine the IP address or domain name to allow access to protected content. These may be your own IP address, the IP address of a trusted partner or customer.

2. Create nginx configuration block

In the nginx configuration file, create a new server block to handle requests that will whitelist.

3. Add allow command

In the server block, add the following allow directive to allow access from the specified IP address or domain name:

 <code>allow 192.168.0.1; allow example.com;</code>

4. Add deny directive (optional)

If you want to deny all access except whitelists, you can add the deny directive:

 <code>deny all;</code>

5. Save the configuration and reload nginx

Save the nginx configuration file and apply the changes to the server:

 <code>sudo systemctl reload nginx</code>

Sample configuration

Here is an example of nginx whitelist configuration:

 <code>server { listen 80; location /protected/ { allow 192.168.0.1; allow example.com; deny all; } }</code>

This configuration will allow requests from the 192.168.0.1 IP address and example.com domain name to access the /protected/ directory, while denied all other requests.
