Ubuntu is a popular Linux distribution that provides a wide range of tools and software for managing and deploying applications. In this article, we will guide you through the process of installing MongoDB on Ubuntu.

Prerequisites

Before you start installing MongoDB, make sure you have the following prerequisites:

• Ubuntu 18.04 or later: MongoDB is compatible with Ubuntu 18.04 or later. If you are using an earlier version of Ubuntu, you may need to upgrade to a newer version.
• Java 8 or later: MongoDB requires Java 8 or later to be installed. You can download the latest version of Java from the official Oracle website.
• Python 3.6 or later: MongoDB supports Python 3.6 or later. You can download the latest version of Python from the official Python website.

Step 1: Update and Upgrade Ubuntu

Before you start installing MongoDB, make sure your Ubuntu system is up-to-date and up-to-speed. You can update your system by running the following command:

sudo apt update

You can upgrade your system by running the following command:

sudo apt full-upgrade

Step 2: Install Java

You will need to install Java on your system to install MongoDB. You can download the latest version of Java from the official Oracle website:

• Download the latest version of Java: Go to the Oracle website and download the latest version of Java.
• Extract the zip file: Extract the zip file to a directory of your choice.
• Add the Java bin directory to your system’s PATH: Add the Java bin directory to your system’s PATH environment variable. You can do this by running the following command:

sudo echo "export PATH=$PATH:/usr/lib/jvm/java-8-oracle/bin" >> ~/.bashrc

Step 3: Install Python

You will need to install Python on your system to install MongoDB. You can download the latest version of Python from the official Python website:

• Download the latest version of Python: Go to the official Python website and download the latest version of Python.
• Extract the zip file: Extract the zip file to a directory of your choice.
• Add the Python bin directory to your system’s PATH: Add the Python bin directory to your system’s PATH environment variable. You can do this by running the following command:

sudo echo "export PATH=$PATH:/usr/lib/python3.x/site-packages" >> ~/.bashrc

Step 4: Install MongoDB

Now that you have installed Java and Python, you can install MongoDB. You can install MongoDB using the following command:

sudo apt install mongodb

Step 5: Start and Configure MongoDB

Once MongoDB is installed, you can start and configure it by running the following command:

sudo service mongodb start

You can configure MongoDB by running the following command:

sudo mongo --config

Step 6: Create a Database and Collection

To create a database and collection, you can use the following command:

sudo mongo --config

You can create a database by running the following command:

db.createDatabase("mydatabase")

You can create a collection by running the following command:

db.createCollection("mycollection")

Step 7: Insert Data into the Database and Collection

To insert data into the database and collection, you can use the following command:

db.mydatabase.mycollection.insertOne({name: "John Doe", age: 30})

Step 8: Query Data from the Database and Collection

To query data from the database and collection, you can use the following command:

db.mydatabase.mycollection.find()

Step 9: Close the MongoDB Shell

To close the MongoDB shell, you can run the following command:

mongo --eval "db.close()"

Troubleshooting

• Error: Cannot connect to MongoDB: If you are having trouble connecting to MongoDB, check that you have installed the correct version of Java and Python, and that you have added the Java and Python bin directories to your system’s PATH environment variable.
• Error: Cannot create database: If you are having trouble creating a database, check that you have installed the correct version of MongoDB, and that you have created a database using the correct command.
• Error: Cannot create collection: If you are having trouble creating a collection, check that you have installed the correct version of MongoDB, and that you have created a collection using the correct command.
