Install and Setup Ghostjs with Ansible

Ansible is fun but need to be intuitive too !

Objective: Install and setup Ghostjs using ansible-playbook

What does the code do:

• calling host file
• setup variables
• install/update required software, packages.
• install mysql and other dependent packages to use ansible modulei.e.PyMySQL and some setuptools mentioned below.
• Set root user password.firstly, if my.cnf file exists, mysql-root-password updateelse, replace my.cnf file with the jinja template created before.
• install nodejs and ghost-cli
• create a directory for ghost and change its permission.
• Run ghost installinteractive comments are generated for active inputs from user tosetup ghost config file i.e. config.production.jsonsilent the errors and let run ghost install process.proceed to next step.
• Now manually set up config.production.jsoncreate a file, add the contents and set the permission.
• ghost is installed, do ghost start.
