Apache 1 virtual host definition listening on 2 ips - how?

  • 772

We have a couple of complex virtual host definitions in our httpd.conf file.

What I mean by that is:

<VirtualHost .....>
....
</VirtualHost>

What I mean by complex is that they are full of rewrite rules and such.

We would like to bind this virtual host on 2 ip addresses. Currently it is bound only to one.

Is it possible to bind a virtual host to 2 ip addresses using a single VirtualHost?

It would make things a lot easier to have a single one if we need to make changes in the future.

  1. You can just place multiple IP/Port specifiers in the definition, as described in the documentation.

    Example:

    <VirtualHost 1.2.3.4:80 2.3.4.5:80 1.2.3.4:8080>
DocumentRoot /path/to/wherever
ServerName example.com
# Stuff goes here
</VirtualHost>

    Just make sure you've got Apache configured with enough NameVirtualHost definitions.

  2. Sure:

    Listen 80

<VirtualHost _default_:80>
    ...
</VirtualHost>

    Alternatively, consider using name-based virtual hosts instead.

  3. You could use...

    Listen 80

<VirtualHost *:80>
...
</VirtualHost>

    ..to bind to any IP on the server

    An easy way to handle this is to extract the common bits into a separate file (e.g., /path/to/foo) and then Include it in your vhost defs:

    <Vitrualhost ...>
  ServerName X
  DocumentRoot Y
  Include /path/to/foo
</Virtualhost>

<Vitrualhost ...>
  ServerName Z
  DocumentRoot A
  Include /path/to/foo
</Virtualhost>

    Note: Do not put /path/to/foo somewhere that will be pulled in by a wildcard Include elsewhere.

  5. I would probably go with the named virtual hosts, AND make the modification to the DNS so that both IPs have A records with the same hostname.
