meteor Replica Sets and Sharding Replica Set Quickstart
Example
Build yourself three servers using whatever physical or virtual hardware you wish. (This tutorial assumes you're using Ubuntu as your operating system.) Then repeat the following instructions three times... once for each server.
# add the names of each server to the host file of each server
sudo nano /etc/hosts
10.123.10.101 mongo-a
10.123.10.102 mongo-b
10.123.10.103 mongo-c
# install mongodb on the server
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
sudo apt-get update
sudo apt-get install mongodb-10gen
# create the /data/ directories
sudo mkdir /data
sudo mkdir /data/logs
sudo mkdir /data/db
# make sure the mongodb user and group have access to our custom directories
sudo chown -R mongodb:mongodb /data
# edit the mongo upstart file in /etc/init/mongodb.conf
sudo nano /etc/init/mongodb.conf
start on started mountall
stop on shutdown
respawn
respawn limit 99 5
setuid mongodb
setgid mongodb
script
exec /usr/bin/mongod --config /etc/mongodb.conf >> /data/logs/mongo-a.log 2>&1
end script
# edit mongodb configuration file
sudo nano /etc/mongodb.conf
dbpath=/data/db
logpath=/data/logs/mongod.log
logappend=true
port=27017
noauth=true
replSet=meteor
fork=true
# add a mongo log-rotation file
sudo nano /etc/logrotate.d/mongod
/data/logs/*.log {

/bin/kill -SIGUSR1 `cat /data/db/mongod.lock 2> /dev/null` 2> /dev/null || true
endscript
}
# make sure mongod service is started and running
sudo service mongodb start
sudo reboot
