Topic: Configuring Apache2 separate domain to a dynamic homepage

[Beyondhelp]

Hi all,

Can just about get my way round apache2, but I can't get this to work.

I have a few domains a.com b.com c.com

a.com is the sites root directory. This works fine.

I want domains b.com and c.com to point to other dynamic pages within a.coms domain, so that if you goto b.com you are essentially taken to another area on he same site as a.com.

Any help would be hugely appreciated.

Believe you need to explain precisely what you mean by "dynamic pages".

Presumably, the DocumentRoot settings for b.com and c.com differ to that for a.com, and yet you want parts of those sites to be served by content from a.com?

So within Apache, could you use Alias or AliasMatch directives within those domains (vhosts?), to pick up content from the directory structure for a.com?

See https://httpd.apache.org/docs/current/mod/mod_alias.html for details and examples.

Please excuse me if I use incorrect terminology I just mean pages on a Joomla site.

I'll try and explain again.

a.com is the main site home page/document root. Within the a.com are a load of pages that can be viewed as a.com/topic_b/

I just want b.com to treat a.com/topic_b/ as its document root.

I tried setting up a complete virtual server config and used topic_b as the document root but it doesn't work as strictly speaking a.com/topic_b is dynamic so it would be a.com/index.php/topic_b.php but that doesn't work either.

The alternative could be a b.com redirect to a.com/topic_b/ but google/bing wont index that as its a redirection.

Ok, so your site content is being dynamically generated by Joomla CMS code, and you want some content overlap across differing domains using Apache.

I'd definitely start with a virtual host for each domain, each with a separate document root, and work from there. I tried the following basic configuration in a test environment, using local host file entries for a.com and b.com.

The Alias directive in the second vhost duly mapped requests for http://b.com to the content below C:/Apache24/htdocs/a.com/topic_b/

I'm going to give this a go and report back.

Thanks

So it comes up with file not found when trying to call topic_b.html, so www.a.com/topic_b which works but calling it via Alias "/" "/var/www/a/topic_b.html" shows file not found.

If I test that location by actually creating a real topic_b.html it does load it fine. So it seems that its pointing to the right place just not loading a dynamic page.

Ok I think I've found a suitable solution.

Using the virtual server config for b.com I've added this:

RewriteEngine on
RewriteRule ^/$ /topic_b/ [R]

So now going to b.com shows b.com/topic_b/ as the landing page which as long as it gets picked up by google etc properly, is totally fine.
