In this step you will download the binaries of MongoDB latest version on an Ubuntu server

Download the MongoDB binaries

Since the current tutorial is running on Ubuntu server let's download the binaries for Ubuntu and uncompress it using below commands.

wget http://downloads.mongodb.org/linux/mongodb-linux-x86_64-ubuntu1604-3.6.3.tgz tar xzvf mongodb-linux-x86_64-ubuntu1604-3.6.3.tgz

Setup the environment

Setup the environment using below commands before you start the MongoDB. They will

• Configure the environment variable PATH
• Create directory for storing the datafiles

cd mongodb-linux-x86_64-ubuntu1604-3.6.3/bin export PATH=$(pwd):$PATH mkdir -p ~/data/db

Start the MongoDB server

The default settings for datafiles is /data/db. You can specify an alternate path for datafiles using the --dbpath option as show below. Run the below command to start the server with the --dbpath and --logpath overrides

./mongod --dbpath ~/data/db --logpath ~/data/mongod.log --fork
