If I have a number of virtual hosts in the sites-enabled
folder, how can I have a common whitelist for all of them?
Aka each one has this block
allow 127.0.0.1;
allow 192.168.0.0/16;
allow x.x.x.x;
deny all;
How can I have that apply to all the virtual hosts by default, instead of having to write it for every subdomain?
Use include
eg put the following text in the file /etc/nginx/shared-configs/whitelist.conf
in the file /etc/nginx/sites-enabled/site1.conf
in the file /etc/nginx/sites-enabled/site2.conf
