Several years ago, I wrote a set of instructions how to install JBoss on a RHEL / CentOS Linux operating system. Then, the procedure utilized the GUI, mouse clicks, and the terminal. Well, as my comfort level with Linux has grown, so has the instructions into a script.

A prerequisite for JBoss is Java JDK. For JBoss 5.1.0.GA, I elected to use Java JDK 6 Build 45. That script is also available on this website, here. Here is the JBoss script.

local_ip_value=$(ifconfig eth0|awk '/inet addr/ {split ($2,A,":"); print A[2]}')
