can someone please help to write a play for starting the application . ( Start command i have grep from "ps -ef | grep java | grep newrelic )

[root@chnr1-book4flights4extapi-1 ~]# ps -ef | grep java | grep newrelic

**Note\*\* -** letter in bold letter is start command.

Command to start the application is :- **nohup** **java -server -Xms1g -Xmx3g -d64 -Dnewrelic.config.distributed\_tracing.enabled=true -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9004 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -XX:+UseG1GC -Dct.ctconfig.consul.server=[http://consul-ctconfig.cltp.com:8500](http://consul-ctconfig.cltp.com:8500) -Dct.common.servertype=book4flights4extapi -Dapp.context.path=book -Dspring.profiles.active=prod,book4flights4extapi -javaagent:/opt/cal/newrelic/newrelic.jar -jar /opt/cal/latest.war &**

**Playbook:**

**tasks:**  
**- name: Create a directory to take the backup of old new relic configuration**  
**file:**  
**path: /opt/cal/newrelic/newrelic\_old**  
**state: directory**  
**mode: ‘0755’**

**- name: To take the backup of all the existing new configuration of newrelic**  
**shell: “mv /opt/cal/newrelic/newrelic\* /opt/cal/newrelic/newrelic\_old/”**

**- name: " To update the new relic version of jar "**  
**copy:**  
**src: /home/raviranjan/newrelic/{{ item }}**  
**dest: /opt/cal/newrelic/**  
**with\_items:**  
**- newrelic.jar**  
**- newrelic.yml**

**- name: To get the running process for newrelic**  
**shell: "ps -ef | grep java | grep newrelic | awk ‘{print $2}’ | xargs kill -9 "**  
**register: running\_process**

**- name: To start the application**

any guidance would be much appreciated

You’re better off using your OS daemon functionality like systemd or rc.d script and letting the os handle all of this rather than trying to reinvent all of that in Ansible. Then you can use a notify to the service module in a handler.
