14.2. Configure Server Instance as a Worker Node
Task: Configure a JBoss Enterprise Application Platform Worker Node
Follow this task to correctly configure a JBoss Enterprise Application Platform instance as a SJWS worker node.
Create a server profile for each worker node
Make a copy of the server profile that you wish to configure as a worker node. (This procedure uses thedefault
server profile.)[user@workstation jboss-ep-5.1]$ cd jboss-as/server [user@workstation server]$ cp -r default/ default-01 [user@workstation server]$ cp -r default/ default-02
Give each instance a unique name
Edit the following line in thedeploy/jbossweb.sar/server.xml
file of each new worker instance:<Engine name="jboss.web" defaultHost="localhost">
Add a uniquejvmRoute
value, as shown. This value is the identifier for this node in the cluster.For thedefault-01
server profile:<Engine name="jboss.web" defaultHost="localhost" jvmRoute="worker01">
For thedefault-02
server profile:<Engine name="jboss.web" defaultHost="localhost" jvmRoute="worker02">
Enable session handling
Uncomment the following line in thedeployers/jbossweb.deployer/META-INF/war-deployers-jboss-beans.xml
file of each worker node:<property name="useJK">false</property>
This property controls whether special session handling is used to coordinate with mod_jk and other connector variants. Set this property totrue
in both worker nodes:<property name="useJK">true</property>
Start your worker nodes
Start each worker node in a separate command line interface. Ensure that each node is bound to a different IP address with the-b
switch.[user@workstation jboss-eap-5.1]$ ./jboss-as/bin/run.sh -b 127.0.0.1 -c default-01
[user@workstation jboss-eap-5.1]$ ./jboss-as/bin/run.sh -b 127.0.0.100 -c default-02
