Error: Error: Unable to find Mongodb Oplog. You must run the server with oplog enabled. Try the following:

                                1. Start your mongodb in a replicaset mode: mongod --smallfiles --oplogSize 128 --replSet rs0

                                2. Start the replicaset via mongodb shell: mongo mongo/meteor --eval "rs.initiate({ _id: ''rs0'', members: [ { _id: 0, host: ''localhost:27017'' } ]})"

                                3. Start your instance with OPLOG configuration: export MONGO_OPLOG_URL=mongodb://localhost:27017/local MONGO_URL=mongodb://localhost:27017/meteor node main.js
