Ansible automated O M tool learning Manual 1. Introduction to ansibleCommon automated O M tools Puppet-developed based on Ruby and adopts a C/S architecture. It is highly scalable and SSL-based, and remote command execution is relatively weak.SaltStack-developed based on Python and adopts the C/S architecture. It is more lightweight than puppet. The configuration syntax uses YMAL to make the configuration script simpler.

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
