mongodb local replicaset

README.md

Install 4.x Community edition: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

• Set /etc/mongod.conf

• sudo service mongod restart

Enter mongo shell: mongo

Enter command: rs.initiate({_id: "replocal", members: [{_id: 0, host: "127.0.0.1:27017"}] }) that should return ok: 1

You should now have a replica set with only a primary node, check this with rs.status()
