<title>Virtual Hosting and Tomcat</title>
</properties>
<body>
<section name="Table of Contents">
<toc/>
</section>
<section name="Assumptions">
<p>
For the sake of this how-to, assume you have a development host with two
host names, <code>ren</code> and <code>stimpy</code>. Let's also assume
one instance of Tomcat running, so <code>$CATALINA_HOME</code> refers to
wherever it's installed, perhaps <code>/usr/local/tomcat</code>.
</p>
<p>
Also, this how-to uses Unix-style path separators and commands; if you're
on Windows modify accordingly.
</p>
</section>
<section name="server.xml">
<p>
At the simplest, edit the <a href="config/engine.html">Engine</a> portion
of your <code>server.xml</code> file to look like this:
</p>
<source>
<Engine name="Catalina" defaultHost="ren">
<Host name="ren" appBase="renapps"/>
<Host name="stimpy" appBase="stimpyapps"/>
</Engine>
</source>
<p>
Note that the directory structures under the appBase for each host should
not overlap each other.
</p>
<p>
Consult the configuration documentation for other attributes of the
<a href="config/engine.html">Engine</a> and <a href="config/host.html">
Host</a> elements.
</p>
</section>
<section name="Webapps Directory">
<p>
Create directories for each of the virtual hosts:
</p>
<source>
mkdir $CATALINA_HOME/renapps
mkdir $CATALINA_HOME/stimpyapps
</source>
</section>
<section name="Configuring Your Contexts">
<subsection name="General">
<p>Contexts are normally located underneath the appBase directory. For
example, to deploy the <code>foobar</code> context as a war file in
the <code>ren</code> host, use
<code>$CATALINA_HOME/renapps/foobar.war</code>. Note that the
default or ROOT context for <code>ren</code> would be deployed as
<code>$CATALINA_HOME/renapps/ROOT.war</code> (WAR) or
<code>$CATALINA_HOME/renapps/ROOT</code> (directory).
</p>
<p><strong>NOTE: The <code>docBase</code> for a context should never be
the same as the <code>appBase</code> for a host.</strong>
</p>
</subsection>
<subsection name="context.xml - approach #1">
<p>
Within your Context, create a <code>META-INF</code> directory and then
place your Context definition in it in a file named
<code>context.xml</code>. i.e.
<code>$CATALINA_HOME/renapps/ROOT/META-INF/context.xml</code>
This makes deployment easier, particularly if you're distributing a WAR
file.
</p>
</subsection>
<subsection name="context.xml - approach #2">
<p>
Create a structure under <code>$CATALINA_HOME/conf/Catalina</code>
corresponding to your virtual hosts, e.g.:
</p>
<source>
mkdir $CATALINA_HOME/conf/Catalina/ren
mkdir $CATALINA_HOME/conf/Catalina/stimpy
</source>
<p>
Note that the ending directory name "Catalina" represents the
<code>name</code> attribute of the
<a href="config/engine.html">Engine</a> element as shown above.
</p>
<p>
Now, for your default webapps, add:
</p>
<source>
$CATALINA_HOME/conf/Catalina/ren/ROOT.xml
$CATALINA_HOME/conf/Catalina/stimpy/ROOT.xml
</source>
<p>
If you want to use the Tomcat manager webapp for each host, you'll also
need to add it here:
</p>
<source>
cd $CATALINA_HOME/conf/Catalina
cp localhost/manager.xml ren/
cp localhost/manager.xml stimpy/
</source>
</subsection>
<subsection name="Further Information">
<p>
Consult the configuration documentation for other attributes of the
<a href="config/context.html">Context</a> element.
