minLevel	4

Prerequisites

Install JDK 1.7 or later and set up the JAVA_HOME environment variable.

Setting up CARBON_HOME

Extract the WSO2 product to a preferred directory in your machine and set the environment variable CARBON_HOME to the extracted directory location.

Running the product as a Linux service

To run the product as a service, create a startup script and add it to the boot sequence. The basic structure of the startup script has three parts (i.e., start, stop and restart) as follows:

Code Block

#!/bin/bash
 
case “$1″ in
start)
   echo “Starting the Service”
;;
stop)
   echo “Stopping the Service”
;;
restart)
   echo “Restarting the Service”
;;
*)
   echo $”Usage: $0 {start|stop|restart}”
exit 1
esac

Given below is a sample startup script. <PRODUCT_HOME> can vary depending on the WSO2 product's directory.

Code Block

language	java

#! /bin/sh
export JAVA_HOME="/usr/lib/jvm/jdk1.7.0_07"

startcmd='<PRODUCT_HOME>/bin/wso2server.sh start > /dev/null &'
restartcmd='<PRODUCT_HOME>/bin/wso2server.sh restart > /dev/null &'
stopcmd='<PRODUCT_HOME>/bin/wso2server.sh stop > /dev/null &'

case "$1" in
start)
   echo "Starting the WSO2 Server ..."
   su -c "${startcmd}" user1
;;
restart)
   echo "Re-starting the WSO2 Server ..."
   su -c "${restartcmd}" user1
;;
stop)
   echo "Stopping the WSO2 Server ..."
   su -c "${stopcmd}" user1
;;
*)
   echo "Usage: $0 {start|stop|restart}"
exit 1
esac

In the above script, the server is started as a user by the name user1 rather than the root user. For example, su -c "${startcmd}" user1

Add the script to /etc/init.d/ directory.

Info

If you want to keep the scripts in a location other than /etc/init.d/ folder , you can add a symbolic link to the script in /etc/init.d/ and keep the actual script in a separate location. Say your script name is prodserver and it is in /opt/WSO2/ folder, then the commands for adding a link to /etc/init.d/ is as follows:

Make executable: sudo chmod a+x /opt/WSO2/prodserver
Add a link to /etc/init.d/: sudo ln -snf /opt/WSO2/prodserver /etc/init.d/prodserver

Install the startup script to respective runlevels using the command update-rc.d . For example, give the following command for the sample script shown in step1:
Code Block
sudo update-rc.d prodserver defaults
The defaults option in the above command makes the service to start in runlevels 2,3,4 and 5 and to stop in runlevels 0,1 and 6.
A runlevel is a mode of operation in Linux (or any Unix-style operating system). There are several runlevels in a Linux server and each of these runlevels is represented by a single digit integer. Each runlevel designates a different system configuration and allows access to a different combination of processes.
You can now st art, stop and restart the server using service <service name> {start|stop|restart} command. You will be prompted for the password of the user (or root) who was used to start the service.
