First, ansible Management command There are several ansible management commands:(1) Ansible: This command is one of the very high usage in daily work, mainly used for temporary one-time operation;(2) Ansible-doc:ansible module document description, for each module has detailed usage instructions and application case in

Ansible is a free, open-source configuration and automation tool developed for Unix-like systems. It is written in Python and is similar to Chef and Puppet. but there is a difference and advantage that we do not need to install any client in the node. It uses SSH to communicate with nodes. In this article, we will install and configure Ansible on CentOS7 and try to manage the two nodes.

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.
