Nginx subdomain configuration

Question

I have nginx acting as a reverse proxy to apache  I now need to add a new subdomain that will serve files from another directory  but at the same time I want all location and proxy pass directives that I have for the default host to apply to the subdomain also   I know that if I copy the rules from the default host to the new subdomain it will work  but is there a way for the subdomain to inherit the rules  Below is a sample configuration  server       listen       80      server name  www somesite com      access log  logs access log      error log  logs error log error       location  mvc         proxy pass  http   localhost 8080 mvc            location  assets         alias    var www html assets        expires     max               a lot more locations    server       listen       80      server name  subdomain somesite com       location                     root    var www some dir                  index  index html index htm                Thanks

You could move the common parts to another configuration file and include from both server contexts. This should work:

server {
  listen 80;
  server_name server1.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

server {
  listen 80;
  server_name another-one.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled (normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org's configuration file is /etc/nginx/sites-enabled and it looks like this:

server {
  listen   80 default_server;
  listen   [2a01:4f8:120:3105::101:1]:80 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-80;
}

server {
  listen   443 default_server;
  listen   [2a01:4f8:120:3105::101:1]:443 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/ssl-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-443;
}

As an example here's the /etc/nginx/include.d/all-common file that's included from both server contexts:

index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;

location ~ /\.ht {
  deny all;
}

location = /favicon.ico {
  log_not_found off;
  access_log off;
}

location ~ /(README|ChangeLog)$ {
  types { }
  default_type text/plain;
}

Another type of solution would be to autogenerate the nginx conf files via Jinja2 templates from ansible  The advantage of this is easy deployment to a cloud environment  and easy to replicate on multiple dev machines
