MongoDB Quick Start - Replica Sets and Sharding

Submitted by alex on

Scaling out 1 node with Replica Set

If you already have a running mongod instance you first need restart it with --replSet

$ mongod --fork --rest --replSet mySetName --port 27017 --dbpath ~/Projects/db/data/mongo/r0 --logpath ~/Library/Logs/mongod-r0.log

Initialize the node via the mongo client

$ mongo
> rs.initiate()
{
        "info" : "Config now saved locally.  Should come online in about a minute.",
        "ok" : 1
}

This node is our Primary Node where read/write is done initially.

> db.messages.insert({City: "Tokyo"})
> db.messages.find()
