Configurations of a replica set
In our example, we will create a replica set using three members on different machines.
The following is the configuration of each machine:
• Mac OS X 10.9.2
• Ubuntu 12.04
• Ubuntu 12.04
We have Mac OS X on our host machine, and we use VMware Fusion to run other ma-
chines at once. The network connections between members are provided by VMware Fu-
sion. Each
mongod
object will be hosted on different machines, so we will have three
members on three separate machines.
The following scheme shows each machine's hostname:
•
mongod1.replicaset.com
•
mongod2.replicaset.com
•
mongod3.replicaset.com
You can set up hostnames by configuring DNS settings or adding hostnames to the
hosts
file. This file can be found in the
/etc/
folder of the Unix operating systems.
The following diagram shows the member's network and relationships:
