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. </p> </subsection> </section> </body> </document>
