Installation of AnsibleAnsible-Based on Python Paramiko development, distributed, no client, lightweight, configuration syntax using Ymal and JINJA2 template language, stronger remote commands to perform operations.Similar automated operations tools are commonly used in many other things:Puppet:-Based on Ruby development, with C/s architecture, strong extensibility, SSL-based, remote command execution is relatively weak.Saltstack:-Based on Python development, the C/S architecture, relatively pup
Playbook1 Playbook is a list consisting of one or more "play"The main function of 2 play is to dress up a pre-merged host into a role defined in advance by a task in ansible. Fundamentally, the so-called task is nothing more than a module that calls Ansible.
