How to execute a remote shell script in ansible

Hello ,

I am new to Ansible and trying to setup for automating deployment process .

I have written a simple playbook to execute a shell script ( at remote host) on remote host using command module .

=============================================

---

- name: start server.

  hosts: app

  remote_user: app

  tasks:

     - name: Start APP Service

       command: /home/app/current-app/etas/util_bin/start_app

       register: comm_out

     - debug: msg="{{ comm_out.stdout }}"

     - debug: msg="{{ comm_out.stderr }}"

==============================================

But it seems that its not able to load the libraries on remote host and fails to start the application process , however the ansible-playbook command line exist with success status .

Error :

===================

/home/app/current-app/etas/bin/eta_registry: error while loading shared libraries: libapp_r64.so.1: cannot open shared object file: No such file or directory\n/home/app/current-app/etas/bin/eta_log_manager: error while loading shared libraries: libapp_r64.so.1: cannot open shared object file: No such file or directory\

======================

Please help on this .

Thanks in Advance!!
