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