Before deploying a replica set
There are some steps you need to take before starting a replica set deployment. First of all,
you should make sure that you have the latest stable version of MongoDB on each ma-
chine.
Note
If you haven't installed MongoDB yet and need help installing MongoDB, read these short
instructions at
http://docs.mongodb.org/manual/installation/
.
Additionally, before deploying a replica set, you must make sure that there aren't any net-
work issues between replica set members. Each machine must see the other, and you must
configure the firewall not to prevent connections. In order to have an effective replica set,
you should configure the machine so that every member can connect to the other.
