The inventory file is used to define the host to be managed. The default location is/etc/ansible/hosts.

Ansible is an automated operations tools, based on the development of Python, the collection of many operations tools (puppet, Cfengine, Chef, func, fabric) The advantages of the implementation of batch system configuration, batch program deployment, batch Run command and other functions.Ansible is a module-based capability that does not have the ability to deploy in batches. The real batch deployment is the module that
