Installing as a Linux Service
Follow the sections below to run a WSO2 product as a Linux service:
Prerequisites
Install JDK 1.6.24 or later or 1.7.* 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:
#!/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.#! /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.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
update-rc.d
command. For example, give the following command for the sample script shown in step1:sudo update-rc.d prodserver defaults
Thedefaults
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.
