How do you conditionally include files in Nginx vhost?

Question

In the lines below, I might have a site-specific configuration file that contains additional fastcgi_params unique to that site. If this file exists I want to load it.

server {
        listen 80 default;
        server_name _;
        root /path/www/$host;

        # Pass PHP scripts to php-fastcgi listening on port 9000
        location ~ \.php {
                include fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;


                if (-f /path/www/$host/nginx.conf) {
                        include /path/www/$host/nginx.conf;
                }
        }
}

However, this doesn't work and the error I get is:

nginx: [emerg] "include" directive is not allowed here in ...

Update

I thought that rather than checking separatly, I could let include check for me.

server {
        listen 80 default;
        server_name _;
        root /path/www/$host;

        # Pass PHP scripts to php-fastcgi listening on port 9000
        location ~ \.php {
                include fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;

                include /path/www/$host/*.nginx;
        }
}

However, this doesn't seem to be working.

Answer 1

include does its thing during server start - runtime variables like $host can't be used, nor is it able to be used in an if context, as you found out.

You'd need to split up the server blocks for different hosts. Sorry!
