Multiple domains on single apache tomcat

问题

I have two domains but only one virtual server which runs a tomcat 7. I have my own ubuntu Linux with full root access running on the virtual server. I setup shorewall firewall which forwards any request on port 80 to port 8080 (where tomcat is listening on).

So I already searched the net but I only find "solution" that do not work in my case. This is what I did so far:

1. I copied my websiteA.war as ROOT.war into the $CATALINA_HOME/webapps/ folder
2. I also copied my websiteB.war as WebsiteB.war into the $CATALINA_HOME/webapps/ folder

3. I modified my $CATALINA_HOME/conf/server.xml in the following way:

   Host name="www.websiteA.com" appBase="webapps" unpackWARs="true" autoDeploy="true"

   Host name="www.websiteB.de" appBase="webapps/websiteB" unpackWARs="true" autoDeploy="true"

   Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"

4. I created the following file ROOT.xml in the folder "$CATALINA_HOME/conf/Catalina/www.websiteB.com" :

   ?xml version="1.0" encoding="UTF-8"?

   Context displayName="www.websiteB.com" docBase="" path=""

   /Context

5. Restarted tomcat. The websiteA.com gets deployed under "/" and websiteB.com gets deployed unter "/websiteB"

6. Entering www.websiteB.com arrives at "/" which means that websiteA is actually shown for websiteB.com

What am I doing wrong here?

Goto your $CATALINA_HOME/conf/server.xml file.

There, you will find the following section:

<Engine name="Catalina" defaultHost="localhost">
    <!-- ... some other stuff ... -->
    <Host name="www.websiteA-Address" appBase="webapps" unpackWARs="true" autoDeploy="true"></Host>
    <Host name="www.websiteB-Address" appBase="directory/of/WAR-files-for-B" unpackWARs="true" autoDeploy="true"></Host>
    <Host name="websiteB-Address" appBase="directory/of/WAR-files-for-B" unpackWARs="true" autoDeploy="true"></Host>
    <Host name="www.websiteC-Address"  appBase="directory/of/WAR-files-for-C" unpackWARs="true" autoDeploy="true"></Host>
</Engine>

So, appBase will be the directory where your will have to put your ROOT.war(!) and name is the domain name that will be mapped onto this directory.

directory/of/WAR-files is a subdirectory in $CATALINA_HOME, that is the same level(!!!) as the standard folder webapps. So both directories coexist!
