Ansible: Playbook to install MongoDB on three servers
In preparation for creating a three MongoDB node replica set, I'm installing the current version of MongoDB via a playbook.
First I'll update each managed node.
Then I'll import the MongoDB repository public key.
After that I'll add the MongoDB respository and install MongoDB.
Finally I'll set MongoDB to auto-start on each of the three nodes.
