JBoss AS 7.1 - Multiple virtual servers with mod_jk

[wgaulke]

Hello,

i am currently stuck in a configuration problem with JBoss AS 7.1.1 together with Apache 2.2 and mod_jk 1.2.32.

I closely followed https://docs.jboss.org/author/display/AS71/AJP+Connectors  - but I have serious trouble getting multiple vhosts to work.

My mod_jk / AJP configuration is correct, if I use only the default virtual hosts.

What I want: I have multiple domains and applications and want to use mod_jk to map the domains to a jboss virtual server.

Some configuration details:

workers.properties:

{noformat}
worker.list=node1,node2,status
worker.node1.port=8009
worker.node1.host=localhost
worker.node1.type=ajp13
worker.node2.port=8009
worker.node2.host=test.com
worker.node2.type=ajp13
{noformat}

standalone.xml

{noformat}
<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false">
            <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
            <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>
            <virtual-server name="default-host" enable-welcome-root="true">
                <alias name="localhost"/>
            </virtual-server>
            <virtual-server name="test.com" default-web-module="myWarfile" />
</subsystem>
...
<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
           <socket-binding name="ajp" port="8009"/>
...
{noformat}

What works: The domain configured for node1 successfully conntects to the default-host. All applications are available through their path. For example node1domain.com/myWarfile

What doesn't work: The domain configured for node2 returns always a 502 - bad gateway. The mod_jk log gives me: (node2) connecting to tomcat failed.

I am really clueless how to solve this problem - does someone here have an idea? Did I miss something in the documentation?

Some update on the issue. I tried a few more things:

1. Add a jboss-web.xml with the following content:

{noformat}
<jboss-web>
    <context-root>/</context-root>
    <virtual-host>test.com</virtual-host>
</jboss-web>
{noformat}

Which did not have any impact.

2. Upgrade mod_jk to the recently release 1.2.36 -> no success either. With 1.2.36 the whole connection for jboss seems not to work.

Any more tipps or advice? Does no one use jboss in production - maybe I should try mod_cluster?

Despite the overwhelming community feedback I found a solution.

For the record and good will of sharing:

My config:

JBossAS 7.1.2 Tag (self compiled)

HTTPD 2.22

Mod_jk 1.2.32

Apache config:

{noformat}
<VirtualHost *:80>
  ServerName test.com
  JkMount /* node1 
</VirtualHost>
<VirtualHost *:80>
  ServerName another-host.com
  JkMount /* node1 
</VirtualHost>
{noformat}

Workers.properties:

{noformat}
worker.list=node1
worker.node1.port=8009
worker.node1.host=localhost
worker.node1.type=ajp13
{noformat}

Jboss Config:

{noformat}
     <subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false" instance-id="node1">
            <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
            <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>
            <virtual-server name="default-host" enable-welcome-root="false">
                <alias name="localhost"/>
                <alias name="another-host.com" />
            </virtual-server>
            <virtual-server name="test.com">     
            </virtual-server>            
        </subsystem>
...
     <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
          ...
        <socket-binding name="ajp" port="8009"/>
          ...
     </socket-binding-group>
{noformat}

Jboss-web.xml:

{noformat}
<jboss-web>
    <context-root>/</context-root>
    <virtual-host>test.com</virtual-host>
</jboss-web>
{noformat}

One remark: it did not work with mod_jk 1.2.36. Also I did not try mod_cluster and have yet not configured SSL.

Maybe someone on this board is willing to share his multidomain configuration - no matter of mod_jk or mod_cluster.

Thanks for posting that, it saved me a lot of time.  One modification I made to get it to work for me was that I needed to set the default-web-module in the default virtual server.  Also, I can confirm that this worked just fine with ssl.  In my case, I had one site domain served with ssl and another without, going to different jboss virtual hosts, and it all worked fine.
