bt-mongodb-cluster

Vagrant Box (CentOS/7) with MongoDB(v3.4) 3-nodes cluster including a replica set.

Start vagrant and setup replica set

Run in terminal: vagrant up

Connect to main box (mongo1) via ssh: vagrant ssh mongo1

Run the setup script for replica set:

    cd /vagrant/
    sudo sh ./setup.sh

Information about port-forwarding

    mongo1.vm.network "forwarded_port", guest: 27017, host: 27017
    mongo2.vm.network "forwarded_port", guest: 27017, host: 27018
    mongo3.vm.network "forwarded_port", guest: 27017, host: 27019

So you are able to connect to the mongo servers from the host via: 127.0.0.1:27017 for mongo1, 127.0.0.1:27018 for mongo2 and so on.
