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.
|
||
|

|
|
</div><h3 id="server.xml">server.xml</h3><div class="text">
|
||
|
|
<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>
|
||
|
|
<div class="codeBox"><pre><code><Engine name="Catalina" defaultHost="ren">
|
||
|
|
<Host name="ren" appBase="renapps"/>
|
||
|
|
<Host name="stimpy" appBase="stimpyapps"/>
|
||
|
|
</Engine></code></pre></div>
|
||
|
|
<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.
|
||

</div><h3 id="Webapps_Directory">Webapps Directory</h3><div class="text">
|
||
|
|
<p>
|
||
|
|
Create directories for each of the virtual hosts:
|
||
|
|
</p>
|
||
|
|
<div class="codeBox"><pre><code>mkdir $CATALINA_HOME/renapps
|
||
|
|
mkdir $CATALINA_HOME/stimpyapps</code></pre></div>

|

|
|
<div class="subsection"><h4 id="General">General</h4><div class="text">
|
||
|
|
<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>$CATALINA_HOME/renapps/ROOT</code> (directory).
|
||
|
|
</p>
|
||
|
|
<p><strong>NOTE: The <code>docBase</code> for a context should never be
|
||
|
|
the same as the <code>appBase</code> for a host.</strong>
|
||
|
|
</p>
|
||
|
|
</div></div>
|
||
|
|
<div class="subsection"><h4 id="context.xml_-_approach__1">context.xml - approach #1</h4><div class="text">
|
||
|
|
<p>
|
||
|
|
Within your Context, create a <code>META-INF</code> directory and then
|
||
|
|
place your Context definition in it in a file named
|
||
|
|
<code>context.xml</code>. i.e.
|
||
|
|
<code>$CATALINA_HOME/renapps/ROOT/META-INF/context.xml</code>
|
||
|
|
This makes deployment easier, particularly if you're distributing a WAR
|
||
|
|
file.
|
||
|
|
</p>
|
||
|
|
</div></div>
|
||
|

<div class="subsection"><h4 id="context.xml_-_approach__2">context.xml - approach #2</h4><div class="text">
|
||
|
|
<p>
|
||
|
|
Create a structure under <code>$CATALINA_HOME/conf/Catalina</code>
|
||
|
|
corresponding to your virtual hosts, e.g.:
|
||
|
|
</p>
|
||
|
|
<div class="codeBox"><pre><code>mkdir $CATALINA_HOME/conf/Catalina/ren
|
||
|
|
mkdir $CATALINA_HOME/conf/Catalina/stimpy</code></pre></div>
|
||
|
|
<p>
|
||
|
|
Note that the ending directory name "Catalina" represents the
|
||
|
|
<code>name</code> attribute of the
|
||
|
|
<a href="config/engine.html">Engine</a> element as shown above.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Now, for your default webapps, add:
|
||
|
|
</p>
|
||
|
|
<div class="codeBox"><pre><code>$CATALINA_HOME/conf/Catalina/ren/ROOT.xml
|
||
|
|
$CATALINA_HOME/conf/Catalina/stimpy/ROOT.xml</code></pre></div>
|
||
|
|
<p>
|
||
|
|
If you want to use the Tomcat manager webapp for each host, you'll also
|
||
|
|
need to add it here:
|
||
|
|
</p>
|
||
|
|
<div class="codeBox"><pre><code>cd $CATALINA_HOME/conf/Catalina
|
||
|
|
cp localhost/manager.xml ren/
|
||
|
|
cp localhost/manager.xml stimpy/</code></pre></div>
|
||
|
|
</div></div>

|
<div class="subsection"><h4 id="Further_Information">Further Information</h4><div class="text">
