Prerequisites

Before you begin the MongoDB installation, ensure that you have the following:

• A system running Ubuntu 18.
• A user account with sudo privileges.
• An internet connection to download the MongoDB package.

Step 1: Update System Packages

The first step is to make sure your system’s package list is up to date. Open a terminal and run the following command:

sudo apt update

This command will refresh the list of available packages and their versions.

Step 2: Install MongoDB

To install MongoDB on Ubuntu 18, you can use the official MongoDB repository. Follow these steps:

2.1 Add MongoDB Repository

Add the MongoDB repository to your system using the wget command:

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

2.2 Create MongoDB Repository File

Create a MongoDB repository file for Ubuntu 18:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

2.3 Install MongoDB

Now, you can install MongoDB by running the following commands:

sudo apt update
sudo apt install -y mongodb-org

This will install the MongoDB server and related packages.

Step 3: Start and Enable MongoDB

After the installation is complete, you need to start the MongoDB service and enable it to start on boot:

Start the MongoDB service using the following command:

sudo systemctl start mongod

3.2 Enable MongoDB on Boot

To ensure MongoDB starts automatically when the system boots, run this command:

sudo systemctl enable mongod

Step 4: Verify MongoDB Installation

To verify that MongoDB has been successfully installed and is running, you can check its status:

sudo systemctl status mongod

If MongoDB is running correctly, you’ll see the status as “active (running).”

Step 5: Access the MongoDB Shell
