Blocking IPs with Nginx

Follow these steps to block an IP address.

1. View the Nginx configuration file locations article to create your local /nginx/example.com directory.
2. Create a file named access.conf in this /nginx/example.com directory.
3. Add the contents from the following sections.
4. Make sure to reload Nginx for the changes to take effect.

location / {
   deny 1.2.3.4;
 }

This blocks the IP address of 1.2.3.4 from accessing your site entirely.

If you want to block access to all IPs while allowing a specific IP to still access your site, use this:

location / {
   allow 9.8.7.6;
   deny all;
 }

This may be helpful if you're working on your site and do not want anyone but you to view it.

You can also create and combine multiple sets of these rules in your access.conf file:

location /subdir {
   allow 1.2.3.4;
   deny all;
 }

 location / {
   deny all;
 }

The above allows 1.2.3.4 to only browse the subdirectory named /subdir. All other IPs are blocked from everywhere in your site.
