Install MongoDB

Overview

This section shows you how to install MongoDB and the MongoDB Shell (mongosh) on an Arm-based Google Axion C4A instance running Red Hat Enterprise Linux. You will download the Arm64 binaries, update your environment, and verify that the database server runs correctly.

Install system dependencies

Install the required system packages:

    

        
        
sudo dnf update -y
sudo dnf install -y libcurl openssl tar wget curl


Download and extract MongoDB

Fetch and unpack the MongoDB Arm64 (aarch64) binaries for RHEL 9.3:

```console
wget https://fastdl.mongodb.org/linux/mongodb-linux-aarch64-rhel93-8.0.12.tgz
tar -xzf mongodb-linux-aarch64-rhel93-8.0.12.tgz
ls mongodb-linux-aarch64-rhel93-8.0.12/bin

    

Add the binaries to your PATH so they are available in every shell session:

    

        
        
echo 'export PATH=~/mongodb-linux-aarch64-rhel93-8.0.12/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

    

Start the MongoDB server

Create a data directory for MongoDB files:

    

        
        
mkdir -p ~/mongodb-data/db

    

Start mongod in the foreground to verify that it launches and to view logs directly:

    

        
        
mongod --dbpath ~/mongodb-data/db

    

Starting the server in the foreground allows you to see real-time logs and is useful for debugging or verifying that MongoDB starts correctly. However, this will occupy your terminal and stop the server if you close the terminal or interrupt it.

Stop the server (for example, with Ctrl+C), then confirm that data files were created:

    

        
        
ls ~/mongodb-data/db/

    

Example output:

    

        
        collection-0-7680310461694759627.wt  index-3-7680310461694759627.wt  mongod.lock      WiredTiger.lock

        
    

Once you’ve confirmed it’s working, you can start MongoDB in the background using the --fork option and redirecting logs to a file. This allows MongoDB to run continuously without tying up your terminal session.

Start mongod in the background with logging enabled so it continues to run after you close the terminal:

    

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

    

Install MongoDB Shell (mongosh)

mongosh is the MongoDB shell used to interact with your database. Download and install mongosh for Arm64:

    

        
        
wget https://github.com/mongodb-js/mongosh/releases/download/v2.5.6/mongodb-mongosh-2.5.6.aarch64.rpm
sudo dnf install -y ./mongodb-mongosh-2.5.6.aarch64.rpm

    

Verify the installation:

    

        
        
mongosh --version

    

Connect to MongoDB with mongosh

Connect to the local server:

    

        
        
mongosh mongodb://127.0.0.1:27017

    

Sample output:

    

        
        Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&...
Using MongoDB: 8.0.12
Using Mongosh: 2.5.6
...
test>

        
    

With MongoDB and mongosh successfully installed and running, you’re now ready to proceed with baseline testing.
