Download MongoDB and Unzip

https://www.mongodb.com/download-center/enterprise/releases

tar -zxvf mongodb-linux-x86_64-enterprise-rhel70-3.6.5.tgz

Renaming

mv mongodb-linux-x86_64-enterprise-rhel70-3.6.5 mongo1

yum install net-snmp

Start the service

./mongod --dbpath /software/mongo1/data --logpath /software/mongo1/log/m.log --port 27017 --fork --smallfiles

Stop the MONGO process

pkill -9 mongo

Copy Mongo2, Mongo3

cp -rf mongo1 mongo2cp -rf mongo1 mongo3

Start three services separately

./mongod --dbpath /software/mongo1/data --logpath /software/mongo1/log/m.log --bind_ip 0.0.0.0 --port 27017 --fork --smallfiles --replSet rs01./mongod --dbpath /software/mongo2/data --logpath /software/mongo2/log/m.log --bind_ip 0.0.0.0 --port 27018 --fork --smallfiles --replSet rs01./mongod --dbpath /software/mongo3/data --logpath /software/mongo3/log/m.log --bind_ip 0.0.0.0 --port 27019 --fork --smallfiles --replSet rs01
