How to execute a backend java program?

[刘松]

Hi, 

  I use ansible 2.0.0. and I want start a java web program which use spring boot and compile as a jar file, but it always don't work.

  I can execute "nohup java -jar xxx.jar &" on the target machine (the target machine is centos 7)，but when I execute through ansible, it don't work.

my playbook is 

- hosts: testservers

  remote_user: root

  tasks:  

   - name: start product
     shell: chdir=/app nohup java -jar /app/product.jar &
     

I think all the method I can , for example, make a .sh file in the target machine, the sh file is

#!/bin/bash

java -jar /app/product.jar > /dev/null 2>&1

and I execute the sh file , it can start .

and the playbook is

shell: chdir=/app nohup ./startproduct.sh &

and I execute the playbook,

the product.jar can not be started yet.

and then I add it to service, the file is

#!/bin/bash

#

#productservice1    start/stop product1

#

# chkconfig: 12345 80 90

# description: start/stop product1

#

### BEGIN INIT INFO

# Description: start/stop product1

### END INIT INFO

function start_product()

{

  nohup java -jar /app/product.jar > /dev/null 2>&1 &

}

function stop_product()

{

    ps -ef | grep /app/product.jar | grep -v grep | awk '{print $2}' | xargs kill -9

}

case "$1" in

    start)

    start_product

    ;;

    stop)

    stop_product

    ;;

    restart)

    stop_product

    start_product

    ;;

    *)

    echo "Usage : start | stop | restart"

    ;;

esac

and I execute the service in target machine, it work!

but I execute it in ansible playbook, it don't work!

service: name=productservice state=started

and I try add

async:45
poll: 0

the playbook still can not start the java program.

I can use playbook kill a process, start tomcat, but can't use it to start a java program( a website, a jar file)

 anybody can help me?

Hello, !

(Sorry can't spell your name).

Try this working example:

- name: Start jenkins

  remote_user: "{{jenkins_owner_user}}"

  shell: cd {{jenkins_home_path_bin}}/ && nohup java -Djenkins.install.runSetupWizard=false -Dhudson.diyChunking=false -DJENKINS_HOME={{jenkins_home_path_data}} -jar ./jenkins.war --httpPort={{jenkins_port}} &

  async: 45

  poll: 0
