This tutorial will help you to install MongoDB 4.0 community release on Ubuntu 18.04 LTS (Bionic) and 16.04 LTS (Xenial).

Step 1 – Setup Apt Repository

First of all, import GPK key for the MongoDB apt repository on your system using the following command. This is required to test packages before installation

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4

Lets add MongoDB APT repository url in /etc/apt/sources.list.d/mongodb.list.

Ubuntu 18.04 LTS:

echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list

Ubuntu 16.04 LTS:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list

Step 2 – Install MongoDB Server

After adding required APT repositories, use following commands to install MongoDB on your systems. It will also install all dependent packages required for MongoDB.

sudo apt update
sudo apt install mongodb-org

If you want to install any specific version of MongoDB, define the version number as below

sudo apt install mongodb-org=4.0.1 mongodb-org-server=4.0.1 mongodb-org-shell=4.0.1 mongodb-org-mongos=4.0.1 mongodb-org-tools=4.0.1

    target_arch: x86_64

Also, connect MongoDB using the command line and execute some test commands for checking proper working.

mongo 

> use mydb;

> db.test.save( { tecadmin: 100 } )
