Install MongoDB and mongosh on Ubuntu Pro 24.04 LTS (Arm64). You will download the binaries, add them to your PATH, create data and log directories, and start the server locally to verify the setup.
For this exercise, mongod runs locally and access control is disabled by default. Keep the server bound to 127.0.0.1 until you configure users and authentication. To accept remote connections later, set --bind_ip (or bindIp in the config) and enable authorization.
Install the required system packages to support MongoDB:
sudo apt update
sudo apt install -y curl wget tar fio openssl libcurl4 net-tools
Fetch and unpack the MongoDB binaries for Arm64:
wget https://fastdl.mongodb.org/linux/mongodb-linux-aarch64-ubuntu2404-8.0.12.tgz
tar -xvzf mongodb-linux-aarch64-ubuntu2404-8.0.12.tgz
sudo mv mongodb-linux-aarch64-ubuntu2404-8.0.12 /usr/local/mongodb
Enable running MongoDB from any terminal session:
echo 'export PATH=/usr/local/mongodb/bin:$PATH' | sudo tee /etc/profile.d/mongodb.sh
source /etc/profile.d/mongodb.sh
Create the database data and log directories and assign ownership to your user:
sudo mkdir -p /var/lib/mongo
sudo mkdir -p /var/log/mongodb
sudo chown -R $USER:$USER /var/lib/mongo /var/log/mongodb
Start mongod in the background and write logs to /var/log/mongodb/mongod.log:
mongod --dbpath /var/lib/mongo --logpath /var/log/mongodb/mongod.log --fork
Sample output:
about to fork child process, waiting until server is ready for connections.
forked process: 3356
child process started successfully, parent exiting
mongosh is the MongoDB shell for running queries and database operations.
Download and install the MongoDB shell for Arm64:
wget https://downloads.mongodb.com/compass/mongosh-2.3.8-linux-arm64.tgz
tar -xvzf mongosh-2.3.8-linux-arm64.tgz
sudo mv mongosh-2.3.8-linux-arm64 /usr/local/mongosh
Add mongosh to the system PATH:
echo 'export PATH=/usr/local/mongosh/bin:$PATH' | sudo tee /etc/profile.d/mongosh.sh
source /etc/profile.d/mongosh.sh
Confirm that MongoDB and mongosh are installed and available:
mongod --version
mongosh --version
You should see output similar to:
db version v8.0.12

2.3.8
Connect to the local instance and verify an interactive prompt:
mongosh mongodb://127.0.0.1:27017
You should see output similar to:
Current Mongosh Log ID: 68b573411523231d81a00aa0
Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+2.3.8
