Apache alias virtual host

Question

I have two applications running in the same server and I would like to have one served from subpath in the url (i.e):

• foo.com -> /var/www/foo
• foo.com/bar -> /var/www/bar

I'm trying to do an alias but is not working:

<VirtualHost *:80>
  ServerAdmin [email protected]
  ServerName foo.com
  DocumentRoot /webapps/foo/current/public
  <Directory /webapps/foo/current/public>
    AllowOverride all
    Options -MultiViews
  </Directory>
  RailsEnv staging
  Alias /blog /webapps/blog/current
 <Directory /webapps/blog/current>
   allow from all
   Options +Indexes
 </Directory>

Do you know why this is not working?

I also tried serverpath directive without any success.

Do you know how to achieve this?

Thanks in advance.

Is your virtualhost working at all? Cos if you need to access it via www. as well as the root of the domain, I would say you need a ServerAlias www.foo.com in there... – Faris

Also, does either app use any mod_rewriteing? – Faris

Oh sorry, actually the address is without the www. I fixed that on the post. The virtualhost is working, I'm able to access it, but if I go to /blogs/ it does nothing. Both applications have mon_rewrite inside their .httaccess – Holder

What do you get? A 404? And what is in the Apache logs? And are you using a [PT] on you rewrite rules for the /blogs directory? – Faris

I get a 404 that is handled by /var/www/foo. I don't have a [PT] rewrite rule. Actually I don't have a rewrite for the /blog... I'm using for other things. Should I have a rewrite and the alias in order to make it work? – Holder

Not necessarily, it depends on your app - it's just that some rewrite rules wont work with aliases unless you have a [PT] (although not all rules, it depends on what it does). Let me have a play with the Apache install on my laptop and I'll get back to you... – Faris

what about using a subdomain such as bar.foo.com. This way it will have its own vhost configuration. – Mahau

the subdomain is the way I have it know, but we wanted to change it to the other way. – Holder

Besides tuning apache configuration, have you ever tried create a symbolic link /var/www/bar to /var/www/foo/bar – Unlucky

Answer 1

Use AliasMatch instead of Alias:

AliasMatch ^/bar/?(.*) /var/www/bar/$1

Or, in your case:

AliasMatch ^/blog/?(.*) /webapps/blog/current/$1

Answer 2

Have you considered using another separate subdomain, like bar.foo.com for your other application?

Here's how you'd set that up:

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/foo
    ServerName foo.com
    ServerAlias foo.com www.foo.com
    ErrorLog logs/foo.com_Error_Log
</VirtualHost>
<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/bar
    ServerName bar.foo.com
    ErrorLog logs/bar.foo.com_Error_Log
</VirtualHost>
