UltraESB - Cloning Script

In some cases you may need to build a UltraESB cluster running in a single machine. In that case you should make sure ports that each UltraESB instance acquire does not conflict with others. This script makes sure that a UltraESB installed in a default location (/opt/ultraesb) is cloned into a given number of instances in /opt/uesb1,2,3.. path. To run this, you have to give number of clones you need to have as a parameter.

#!/bin/bash



for step in {1..$1}

do

    mkdir /opt/uesb$step

   

    #Create a clone of UlatraESB

    cp -r /opt/ultraesb/* /opt/uesb$step/

   

    #Change ULTRA_HOME

    sed -i "s/\/opt\/ultraesb/\/opt\/uesb$step/g" /opt/uesb$step/bin/ultraesb-daemon.sh
