💻ANSIBLE Auto Configure your server for Nginx|Reactjs and Laravel|php env on ONE click👆

#ansible #playbook #automation #server

Let setup the ansible:

you need one "MASTER" and multiple "SLAVE" node to control the slave configuration.

Important

  • its an configuration management tool, also open-source.
  • we used "YAML" for scripting language.
  • it implement worker on "push management" model.
  • one "Master" configure multiple servers "nodes".
  • it communicate agent/nodes throw "SSH" method.
  • script are called "PLAY BOOKS".
  • the machain where ansible is installed called "ANSIBLE SERVER".
  • the set of commands to be executed in nodes/client called " MODULE"
  • metadata of servers or agent/nodes/clients called "Inventory"
  • inventory default location will be --> /etc/ansible/host

How to connect master and slave

create an SSH-KEY and paste the same in all slave servers.
So, you connect with all different nodes through IP with same private-key.
