setting up virtual hosts. These scenarios are those involving multiple

web sites running on a single server, via <a href="name-based.html">name-based</a> or <a href="ip-based.html">IP-based</a> virtual hosts.

|
|
|
|
<p>Your server has a single IP address, and multiple aliases (CNAMES)
|
|
point to this machine in DNS. You want to run a web server for
|
|
<code>www.example.com</code> and <code>www.example.org</code> on this
|
|
machine.</p>
|
|
|
|
<div class="note"><h3>Note</h3><p>Creating virtual
|
|
host configurations on your Apache server does not magically
|
|
cause DNS entries to be created for those host names. You
|
|
<em>must</em> have the names in DNS, resolving to your IP
|
|
address, or nobody else will be able to see your web site. You
|
|
can put entries in your <code>hosts</code> file for local
|
|
testing, but that will work only from the machine with those
|
|
hosts entries.</p>
|
|
</div>
|
|
|
|
<div class="example"><h3>Server configuration</h3><p><code>
|
|
|
|
|
|
# Ensure that Apache listens on port 80<br />
|
|

# Listen for virtual host requests on all IP addresses<br />

|
|
</span>

|
</VirtualHost>
|
|
</code></p></div>
|
|
|
|
<p>The asterisks match all addresses, so the main server serves no
|
|
requests. Due to the fact that <code>www.example.com</code> is first
|
|
in the configuration file, it has the highest priority and can be seen
|
|
as the <cite>default</cite> or <cite>primary</cite> server. That means
|
|
that if a request is received that does not match one of the specified
|
|
<code>ServerName</code> directives, it will be served by this first
|
|
<code>VirtualHost</code>.</p>
|
|
|
|
<div class="note">
|
|
<h3>Note</h3>
|
|
|
|
<p>You can, if you wish, replace <code>*</code> with the actual
|
|
IP address of the system. In that case, the argument to
|
|
<code>VirtualHost</code> <em>must</em> match the argument to
|
|
<code>NameVirtualHost</code>:</p>
|
|
|
|
<div class="example"><p><code>
|
|
NameVirtualHost 172.20.30.40<br />
|
|
<br />
|
|
<VirtualHost 172.20.30.40><br />
|
|
# etc ...
|
|
</code></p></div>
|
|
|
|
<p>However, it is additionally useful to use <code>*</code>
|
|
on systems where the IP address is not predictable - for
|
|
example if you have a dynamic IP address with your ISP, and
|
|
you are using some variety of dynamic DNS solution. Since
|
|
<code>*</code> matches any IP address, this configuration
|
|
would work without changes whenever your IP address
|
|
changes.</p>
|
|
</div>
|
|
|
|
<p>The above configuration is what you will want to use in almost
|
|
all name-based virtual hosting situations. The only thing that this
|
|
configuration will not work for, in fact, is when you are serving
|
|
different content based on differing IP addresses or ports.</p>

|
|
<p>The server machine has two IP addresses (<code>192.168.1.1</code>
|
|
and <code>172.20.30.40</code>). The machine is sitting between an
|
|
internal (intranet) network and an external (internet) network. Outside
|
|
of the network, the name <code>server.example.com</code> resolves to
|
|
the external address (<code>172.20.30.40</code>), but inside the
|
|
network, that same name resolves to the internal address
|
|
(<code>192.168.1.1</code>).</p>
|
|
|
|
<p>The server can be made to respond to internal and external requests
|
|
with the same content, with just one <code>VirtualHost</code>
|
|
section.</p>
|
|
|
|
<div class="example"><h3>Server configuration</h3><p><code>
|
|
|
|

than the fully qualified host name
|

<code>server.example.com</code>.</p>
|
|
|
|
<p>Note also that, in the above example, you can replace the list

respond the same on all addresses.</p>

<p>The following example allows a front-end machine to proxy a
|
|
virtual host through to a server running on another machine. In the
|
|
example, a virtual host of the same name is configured on a machine
|
|
at <code>192.168.111.2</code>. The <code class="directive"><a href="../mod/mod_proxy.html#proxypreservehost on">ProxyPreserveHost On</a></code> directive is
|
|
used so that the desired hostname is passed through, in case we are
|
|
proxying multiple hostnames to a single machine.</p>
|
|
|
|
<div class="example"><p><code>
|
|
<VirtualHost *:*><br />
|
|
ProxyPreserveHost On<br />

|
|

<p>Using such a default vhost with a wildcard port effectively prevents

served from the primary name-based vhost (the vhost for that

address/port appearing first in the configuration file).</p>

<p>The default vhost for port 80 (which <em>must</em> appear before any

|
|
|
|
<p>The name-based vhost with the hostname
|
|
<code>www.example.org</code> (from our <a href="#name">name-based</a> example, setup 2) should get its own IP
|
|
address. To avoid problems with name servers or proxies who cached the

|
old IP address for the name-based vhost we want to provide both

variants during a migration phase.</p>
|
|
|
|
<p>
|
|
The solution is easy, because we can simply add the new IP address
|
|
(<code>172.20.30.50</code>) to the <code>VirtualHost</code>
|
|
directive.</p>

|
|
<p>We have a server with two name-based vhosts. In order to match the
|
|
correct virtual host a client must send the correct <code>Host:</code>
|
|
header. Old HTTP/1.0 clients do not send such a header and Apache has
|
|
no clue what vhost the client tried to reach (and serves the request
|
|
from the primary vhost). To provide as much backward compatibility as
|
|
possible we create a primary vhost which returns a single page
|
|
containing links with an URL prefix to the name-based virtual
|
|
hosts.</p>

<p>Due to the <code class="directive"><a href="../mod/core.html#serverpath">ServerPath</a></code>
|
|
directive a request to the URL
|
|
<code>http://www.sub1.domain.tld/sub1/</code> is <em>always</em> served
|
|
from the sub1-vhost.<br /> A request to the URL
|
|
<code>http://www.sub1.domain.tld/</code> is only
|
|
served from the sub1-vhost if the client sent a correct
|
|
<code>Host:</code> header. If no <code>Host:</code> header is sent the
|
|
client gets the information page from the primary host.</p>
|
|
|
|
<p>Please note that there is one oddity: A request to
|
|
<code>http://www.sub2.domain.tld/sub1/</code> is also served from the

|
sub1-vhost if the client sent no <code>Host:</code> header.</p>
|
|
|

<p>The <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> directives

are used to make sure that a client which sent a correct

with or without URL prefix.</p>
