Ansible step3 (Play books)

 ---

- hosts: myinventory

  tasks: 

  - name: Install HTTPD Pkg

    yum: name=httpd state=latest

  - name: Start HTTPD service

    service: name=httpd status=retarted


That's it......above play book is ready to install httpd service and start the service , saved as 'install.yml'

How to validate the playbook syntax is correct?

ansible-playbook install.yml --syntax-check

if there is any error then it will display the error msg on the screen


How to run the playbook?

ansible-playbook install.yml  

if you don't mention the 'inventory' then it will take default inventory file from /etc/ansible/hosts

otherwise you have to mention the inventory like below

ansible-playbook -i myinventory install.yml  


Wowww...you have successfully executed the playbook and it installs httpd service and service is started....playbook output will gives you number of successfully execution, failures etc.



Let's write a play book for uninstalling the httpd service


---

- hosts: myinventory

  tasks: 

  - name: Uninstall HTTPD Pkg

    yum: name=httpd state=absent

 


save the above playbook as unistall.yml


Run the uninstall playbook as below

ansible-playbook -i myinventory uninstall.yml
