How to install MongoDB on Lubuntu 16.04

MongoDB is a high performance, schema free document oriented database, sometimes referred as no-SQL database. MongoDB is perfect for storing large data that has no relationship with other table/collection, in this article i'm going to show you how to install MongoDB on Lubuntu 16.04.

Step by step how to install MongoDB on Lubuntu 16.04

• open command line or terminal on lubuntu by pressing CTRL + ALT + T
• add MongoDB 3.2 to the source.list

echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

• run update command

sudo apt-get update

• install mongodb

sudo apt-get install -y mongodb-org

Pin MongoDB specific version

The apt-get command will upgrade the packages when a newer version becomes available. To prevent unintended upgrades, pin the package. To pin the version of MongoDB at the currently installed version, issue the following command sequence:

echo "mongodb-org hold" | sudo dpkg --set-selections
echo "mongodb-org-server hold" | sudo dpkg --set-selections
echo "mongodb-org-shell hold" | sudo dpkg --set-selections
echo "mongodb-org-mongos hold" | sudo dpkg --set-selections
echo "mongodb-org-tools hold" | sudo dpkg --set-selections
