Multiple fastcgi projects as subdomains for nginx

I have directory containing FastCGI projects, to be more specific different versions of the same project. For example, there are ver1 and ver2 directories located at /some/dir/project/ and I want them to be ver1.project.example.com and ver2.project.example.com respectively.

How should I do it with nginx wi开发者_如何学Gothout creating different configs for each version and assuming that new versions may be added dynamically?

in /etc/nginx/sites-enabled/project:

server {
  server_name ~^(?<version>\w+)\.project\.example\.com;
  root /some/dir/project/$version;
  include fastcgi_params;
}

adding a new version directory at /some/dir/project/version99 will automatically make it available at version99.project.example.com.

Regarding the multiple config issue., it can be solved using an nginx inclusion file include fastcgi_params;. I don't know about variable server and socket locations, however, you should probably use multiple clauses for that. To make things quicker you could write something like add-fcgi-subdomain.sh. I resolved this issue once using templates for nginx configs and shell scripts to generate them from /var/www.
