Local Replica Set

local-replication.sh

mkdir ~/tmp_mongo_data1
mkdir ~/tmp_mongo_data2
mkdir ~/tmp_mongo_data3

# In separate terminals
mongod --dbpath ~/tmp_mongo_data1 --port 5000 --replSet ben
mongod --dbpath ~/tmp_mongo_data2 --port 5001 --replSet ben
mongod --dbpath ~/tmp_mongo_data3 --port 5002 --replSet ben

# Then setup replication in a 4th terminal
echo 'rs.initiate({ _id: "ben", members: [ { _id: 0, host: "localhost:5000" } ] })' | mongo localhost:5000
echo 'rs.add("localhost:5001")' | mongo localhost:5000
echo 'rs.add("localhost:5002")' | mongo localhost:5000

# Now you can connect to your replica set
mongo localhost:5000
