How to deploy a Java Linux Daemon with Java Servcie Wrapper

Java Service Wrapper (http://wrapper.tanukisoftware.com/doc/english/integrate.html) is a tool that provides a set of binaries and scripts for different architectures and operating systems that allow Java developers to run a Java application as a service daemon.

For this post I used a 64-bit CentOS PC as a server.

The source code of my test program is :

import java.text.SimpleDateFormat;import java.util.Date;/** * @author XingNing OU */public class SegmentServiceMain {    public static void main(String[] args) {        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");        while (true) {            System.out.println(sdf.format(new Date()));            try {                Thread.sleep(2000L);            } catch (InterruptedException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }        }    }}

 

1. Preparing the environment:

# mkdir -p /data/app/segment/bin# mkdir -p /data/app/segment/conf# mkdir -p /data/app/segment/logs# cp -r segment.jar /data/app/segment/bin/

 

2. Download and install Java Service Wrapper for Linux:

# wget http://wrapper.tanukisoftware.com/download/3.5.25/wrapper-linux-x86-64-3.5.25.tar.gz

3. Extract the package and copy the files needed:

# tar -zxvf wrapper-linux-x86-64-3.5.25.tar.gz# cd wrapper-linux-x86-64-3.5.25# cp bin/wrapper /data/app/segment/bin/# cp src/bin/sh.script.in /data/app/segment/bin/# cp lib/* /data/app/segment/bin/# cp conf/wrapper.conf /data/app/segment/conf/

4. Rename the servcie script and set correct permissions:

# cd /data/app/segment/bin/# mv sch.script.in segment-service# chmod +x segment-servcie

5. Changeing some directive from the config file (wrapper.conf)

6. Edit inti script (segment-service)

7. Run the application at boot time:

# ln -s /data/app/segment/bin/segment-service /etc/init.d/segment-service# chkconfig --levels 235 segment-service on
