Multi-site with two sites sharing the same domain?

Question

There is absolutely no problem to have multi sites, where:

• domain1.com points to site A
• domain2.com points to site B

But I want to have multi-site setup, where:

• domain1.com points to site A
• domain1.com/blabla points to site B

I was doing everything to solve it, for example using directory structure like that:

• domain1.com
• domain1.com.blabla

or using file sites.php with content:

$sites = array(
'domain1.com' => 'domain1.com',
'domain1.com' => 'domain1.com.blabla',
);

Nothing works, site 'domain1.com' takes all traffic.

FYI:

• I'm using nginx.
• I'm using Drupal 7.
• I do not want to use the module Domain as I want to have separated databases.

Please help!

Answer 1

I have done this before. Given a generic location / { ... } entry for Nginx which serves domain1.com to make the subdirectory install work I did the following 2 steps. I am not aware of a solution that doesn't involve making a symlink.

Step 1:

In your Nginx configuration:

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            index index.php;
            try_files $uri $uri/ @rewrite;
            expires max;
            # Uncomment to enable naxsi on this location
            # include /etc/nginx/naxsi.rules
    }

    location /blabla {
     try_files $uri $uri/ /blabla/index.php?$args;
    }
    location ~ /blabla/.+\.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
            webuser /usr/share/nginx/html;
    }

Step 2:

Then wherever your docroot is for your site you add an alias with your subfolder name to the main docroot, allowing the path to be valid for Drupal:

$ pwd
/usr/share/nginx/html

user@localhost:/usr/share/nginx/html$ find . -type l -ls
41059    0 lrwxrwxrwx   1 webuser    webuser           21 Sep 25 01:58 ./blabla -> /usr/share/nginx/html

You will still need your sites.php configuration as you have listed. You will need to restart Nginx.
