Installing GlassFish application Server cluster on Linux

GlassFish is a Java EE open source application server. The following instructions demonstrate how to install GlassFish 2.1.1 on any Linux platform.

http://glassfish.java.net/javaee5/build/GlassFish_LB_Cluster.html contains full information on downloading and installing glassfish clusters and load balancer plugin.

I am going to explain the steps I took to install glassfish clusters as I didn't require load balance support.

Please note all commands will require elevated privileges.

1. Download binary installer from http://glassfish.java.net/downloads/v2.1.1-final.html 
save to /opt directory.

2. Ensure JAVA_HOME variable is set to JDK directory

3. Within the /opt directory run java -Xmx256m -jar glassfish-installer-v2.1.1-b31g-linux.jar

INSTALLATION COMPLETE is displayed
This UN-bundles glassfish and installs under a new directory 'glassfish'

4. Change to glassfish directory cd glassfish/


5. Change permissions on lib/ant/bin sub directory using chmod -R +x lib/ant/bin


6. Run lib/ant/bin/ant -f setup-cluster.xml . If successful you get BUILD SUCCESSFUL displayed

7. From /opt/glassfish/bin run ./asadmin start-domain domain1 to start to default domain.
Domain [domain1] is running is displayed

8. Browse to http://localhost:8080/ to confirm Enterprise server is now running.

9. Browse to http://localhost:4848/ to access admin console. Default user name and password are username: admin, password: adminadmin . You can change this from the Application Server settings on the web admin interface page.

The server is now running and now we are going to look at creating a one machine cluster.

10. Change to directory /opt/glassfish/samples/quickstart/clusterjsp

Run /opt/glassfish/bin/asant setup-one-machine-cluster

This does the following:

Creates a cluster with name cluster1
Creates a node-agent with name cluster1-nodeagent
Starts the above
Creates two instances under the cluster

You can change these default values under /opt/glassfish/samples/quickstart/clusterjsp/cluster.properties before running

BUILD SUCCESSFUL is displayed

12. Start the cluster using glassfish/bin/asant start_cluster 

BUILD SUCCESSFUL is displayed again


13. View and confirm node with two instances is setup from http://localhost:4848/  select node agent then cluster1-nodeagent on the left pane




If you need to test the two instances you can simply deploy an application in glassfish and browse to the instance using http:localhost:PORT/appname 

If you continue reading the link below you can learn how to use the load balancer plugin and set up Sun Java System Web Server for this.
