How to Create a MongoDB Instance on a VPS
Deploying MongoDB on a Virtual Private Server (VPS) gives you complete control over your database infrastructure—ideal for developers, startups, and organizations prioritizing performance, flexibility, and data sovereignty. This guide will walk you through the advanced steps to install, configure, secure, and optimize MongoDB on a VPS.
🛠️ Step 1: Update Your System
sudo apt update && sudo apt upgrade -ySet your hostname and timezone:
hostnamectl set-hostname mongodb-server
timedatectl set-timezone UTC📦 Step 2: Install MongoDB
1. Import MongoDB GPG Key
wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | sudo gpg --dearmor -o /usr/share/keyrings/mongodb-server-6.0.gpg2. Add the MongoDB Repository
echo "deb [ signed-by=/usr/share/keyrings/mongodb-server-6.0.gpg ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-6.0.listNote: Replace focal with jammy or your version if using Ubuntu 22.04.
3. Install MongoDB
sudo apt updatesudo apt install -y mongodb-org🧪 Step 3: Start and Enable MongoDB
sudo systemctl start mongodsudo systemctl enable mongodCheck status:
sudo systemctl status mongod🔐 Step 4: Secure Your MongoDB Server
By default, MongoDB binds to 127.0.0.1. If you want remote access:
1. Edit the Config
sudo nano /etc/mongod.confFind the bindIp line under net: and modify:
bindIp: 127.0.0.1,0.0.0.02. Enable Authentication
Under the security: section, add:
security:
authorization: enabledRestart MongoDB:
sudo systemctl restart mongod👤 Step 5: Create Admin User
Access the MongoDB shell:
mongoshCreate an admin user:
use admin
db.createUser({
user: "admin",
pwd: "StrongPassword123!",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})Exit with exit, then test login:
mongosh -u admin -p --authenticationDatabase admin🛡️ Step 6: Harden the VPS and MongoDB
1. UFW Firewall
sudo ufw allow OpenSSH
sudo ufw allow 27017/tcp
sudo ufw enableFor remote access from a single IP:
sudo ufw allow from YOUR.IP.ADDRESS to any port 270172. Fail2Ban (SSH Protection)
sudo apt install fail2ban -ysudo systemctl enable fail2ban⚙️ Step 7: Advanced Optimization (Optional)
1. Replica Set for High Availability
Modify /etc/mongod.conf:
replication:
replSetName: "rs0"Initialize:
mongosh
rs.initiate()2. Backup Strategy
Use mongodump for backups:
mongodump --out /var/backups/mongodb/$(date +%F)Automate with cron:
crontab -e
# Daily at 2 AM
0 2 * * * /usr/bin/mongodump --out /var/backups/mongodb/$(date +\%F)3. Use TLS/SSL for Encrypted Connections
Generate certificates and configure net.ssl section in mongod.conf. This requires more setup and a trusted certificate authority (CA).
🧪 Step 8: Test Your Deployment
You can test remote connectivity:
mongosh "mongodb://admin:StrongPassword123!@your-server-ip:27017/admin"Replace your-server-ip with your VPS IP or domain name.
📊 Step 9: Monitor Your MongoDB
Consider tools like:
MongoDB Atlas Monitoring Agent (optional)
Prometheus + Grafana with exporters
Custom alerting with cron and logwatch
You can also watch logs directly:
sudo tail -f /var/log/mongodb/mongod.log✅ Final Checklist
MongoDB installed and running
Remote access secured
Admin authentication enforced
Firewall configured
Backups in place
Optional monitoring enabled
🧩 Conclusion
Running MongoDB on a VPS gives you unmatched flexibility, but it requires careful attention to security, backups, and performance. By following this guide, you’ve created a secure and production-ready MongoDB instance, ready to scale as your application grows.
