Hey there, tech enthusiast!
Today, we'll learn how to create a new user in MongoDB with admin privileges. This is a crucial step for database security, so let's make it happen!
⏱️ Estimated time: 5 minutes
Before We Start 📝
Make sure:
- MongoDB is installed and running
- You have access to the terminal
- MongoDB service is active
Pro tip: Always use strong passwords in production environments!
Let's Create a MongoDB User 👤
- First, connect to MongoDB shell:
mongosh
- Switch to admin database:
use admin
- Create your new user 🆕
db.createUser({
user: "root",
pwd: "password",
roles: [ "userAdminAnyDatabase", "dbAdminAnyDatabase", "readWriteAnyDatabase" ]
})
Let's break down those roles 📚
The roles we're assigning here are pretty powerful:
- userAdminAnyDatabase: Can manage users for any database
- dbAdminAnyDatabase: Can perform admin tasks on all databases
- readWriteAnyDatabase: Can read and write to any database
⚠️ Security Note:
Remember to:
- Change "password" to a strong password
- Store credentials securely
- Never share your admin passwords
- Exit the MongoDB shell:
quit
Verification Step ✅
You can test your new user by logging in with these credentials.
Common Issues & Solutions 🔧
- If you get an "Authentication failed" error:
- Double-check your password
- Ensure you're using the correct database
- If you can't create a user:
- Verify you're in the admin database
- Check if you have sufficient privileges
Additional Tips 💡
- Keep your passwords complex and secure
- Document your user credentials safely
- Regular audit of user access is recommended
- Consider using environment variables for passwords in production
⏱️ That's it! In just about 5 minutes, you've successfully created a MongoDB admin user.
