Wordpress Wordpress Multi-site WPMU

Just to update this topic with my working subdomain WPMU site centminmod beta config:

Code:

# Centmin Mod Getting Started Guide
# must read http://centminmod.com/getstarted.html

# redirect from non-www to www
# uncomment, save file and restart Nginx to enable
# if unsure use return 302 before using return 301
#server {
#            listen   80;
#            server_name domain.com;
#            return 301 $scheme://www.domain.com$request_uri;
#       }

map $uri $blogname{
    ~^(?<blogpath>/[^/]+/)files/(.*)    $blogpath ;
}
map $blogname $blogid {
    default -999;
        include /home/nginx/domains/domain.com/public/wp-content/uploads/nginx-helper/map.conf ;
}


server {
 
  server_name domain.com *.domain.com;

    if ($uri !~ wp-content/plugins) {

    }

    # Rewrite multisite '.../wp-.' and '.../.php'.
    if (!-e $request_filename) {
        rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
        rewrite ^/[_0-9a-zA-Z-]+.(/wp-admin/.\.php)$ $1 last;

    }
 
  include /usr/local/nginx/conf/staticfiles.conf;

  include /usr/local/nginx/conf/drop.conf;
  #include /usr/local/nginx/conf/errorpage.conf;
  include /usr/local/nginx/conf/vts_server.conf;
}

and you need two wordpress plugins to install:
1. WordPress MU Domain Mapping
2. Nginx Helper
