MongoDB Installation on AWS Ubuntu EC2: Complete Beginner’s Guide
MongoDB is one of the most popular NoSQL databases used for modern, scalable applications. This guide will help you install MongoDB on an AWS Ubuntu EC2 instance using the official MongoDB repository.
1. Update Your Ubuntu Server
SSH into your EC2 instance:
ssh -i your-key.pem ubuntu@your-ec2-public-ip
Update packages:
sudo apt update && sudo apt upgrade -y
2. Import MongoDB Public GPG Key
curl -fsSL https://pgp.mongodb.com/server-7.0.asc | \
sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg \
–dearmor
sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg \
–dearmor
3. Add the MongoDB Repository for Ubuntu
echo “deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list
Replace jammy with your Ubuntu version if needed:
Ubuntu 22.04 →
Ubuntu 20.04 →
Ubuntu 22.04 →
jammyUbuntu 20.04 →
focal4. Install MongoDB
sudo apt update
sudo apt install -y mongodb-org
sudo apt install -y mongodb-org
5. Start & Enable MongoDB Service
sudo systemctl start mongod
sudo systemctl enable mongod
sudo systemctl status mongod
sudo systemctl enable mongod
sudo systemctl status mongod
If status shows active (running) → MongoDB is installed successfully.
6. Allow MongoDB Port on AWS Security Group
MongoDB default port:
27017
Go to AWS Console → EC2 → Security Groups → Inbound → Add:
| Type | Protocol | Port | Source |
|---|---|---|---|
| Custom TCP | TCP | 27017 | Your IP |
⚠️ Do NOT open 0.0.0.0/0 for production.
Whitelist specific IPs only.
7. Test MongoDB Shell
mongosh
To show databases:
show dbs
8. Enable Remote Access (Optional)
Edit config file:
sudo nano /etc/mongod.conf
Find:
bindIp: 127.0.0.1
Change to:
bindIp: 0.0.0.0
Restart:
sudo systemctl restart mongod
⚠️ Secure MongoDB with users if enabling remote access.
9. Create Admin User (Highly Recommended)
Inside the Mongo shell:
use admin
db.createUser({
user: “admin”,
pwd: “StrongPassword123”,
roles: [ { role: “root”, db: “admin” } ]
})
db.createUser({
user: “admin”,
pwd: “StrongPassword123”,
roles: [ { role: “root”, db: “admin” } ]
})
Login using:
mongosh -u admin -p StrongPassword123 –authenticationDatabase admin

sudo tail -f /var/log/mongodb/mongod.log
