Running multiples instances of JBoss AS in a physical server

In this tutorial, we are using CentOS, JDK6 and JBoss 5.1.x.

Remember that you can only run a process in the same IP/port and this is the reason we need this information if we are going to use multiples JBoss instances.

We go to $JBOSS_HOME/server directory, where default profiles are configured and we create profile1 and profile2 for our two JBoss instances. 

   [root@neodoo-00 ~]# cd /opt/java/jboss/server/
       
   [root@neodoo-00 server]# cp -Rf default profile1
   [root@neodoo-00 server]# cp -Rf default profile2

[edit] Running multiples instances of JBoss AS with a diferent IP address

We only need to use a diferent IP address for each JBoss instante.

In our example, we start 2 servers (we have two IP address configured): one with profile1 at IP 172.24.160.1 and the other with profile2 at IP 172.24.160.2. 

   /opt/java/jboss/bin/run.sh -c 172.24.160.1 -b profile1

   /opt/java/jboss/bin/run.sh -c 172.24.160.2 -b profile2 -Djboss.messaging.ServerPeerID=1

[edit] Running multiples instances of JBoss AS with a single IP address

If you only hace an IP address, we will have to configure all nodes modifying its ports.

[edit] Setting ports manually

You can do it manually modifying a lot of files but there is a easiest to do it we explain next.

[edit] Setting ports using ServiceBindingManager

Instead of to reshape all the ports manually, you can easily configure ports using ServiceBindingManager. This service allows to rotate a fixed amount all the ports of a JBoss instance.

This information is in the file bindings-jboss-beans.xml from the profile you are going to execute. 

   [root@neodoo-00 ~]# vi /opt/java/jboss/server/default/conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml

The simplest way to use is from command line. 


   [root@neodoo-00 ~]# cd /opt/java/jboss/bin

   [root@neodoo-00 ~]# run.sh -c profile1

   [root@neodoo-00 ~]# run.sh -c profile2 -Djboss.service.binding.set=ports-01

With this example, an instance of JBoss AS is running with the profile 'default' using the definition of ports-01 with all ports moved a quantity of 100. Look at the file bindings-jboss-beans.xml the default definition of ports-01.

You can also force JBoss instance to use 'ports-01' modifying bindings-jboss-beans.xml. In our example, We are going to do it with profile2 

   [root@neodoo-00 ~]# vi /opt/java/jboss/server/profile2/conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml

You can see there is some definitions ready to use and by default, we are going to use the group 'ports-01' (rotate 100 to each port from profile 2). 

   <parameter>${jboss.service.binding.set:ports-01}</parameter>

Now, you can start this node linked to profileboth nodes which are using differents ports with same IP.

Now, start the first node (it uses default ports). 

   ./run.sh -c profile1

You can access at http://ip_server:8080

In another console, start the second node (it use ports moved 100 from default). 

   ./run.sh -c profile2

You can access at http://ip_server:8180

[edit] Shutdown JBoss instances

AS we have several JBoss instances running, we have to indicate which we want to stop.

Shutdown the first instante profile1. 

   $JBOSS_HOME/bin/shutdown.sh -s jnp://localhost:11099

Shutdown the instance profile 2. 

   $JBOSS_HOME/bin/shutdown.sh -s jnp://localhost:11199


Thanks to Apser to leave us the virtual machines !
