How to Install and Secure MongoDB on Ubuntu Server 22.04

#### Introduction MongoDB is a leading NoSQL database known for its flexibility, scalability, and performance. It is widely used in modern web applications to handle unstructured data and large volumes of information efficiently. This tutorial will walk you through the installation and initial security setup of MongoDB on Ubuntu Server 22.04. Hosting MongoDB on an EcoStack Cloud VPS provides a robust platform for your database needs. #### Requirements - A VPS running Ubuntu Server 22.04. EcoStack Cloud offers reliable VPS hosting with easy SSH access. - Basic knowledge of SSH and terminal commands. #### Steps to Install and Secure MongoDB on Ubuntu Server 22.04 ##### Step 1: Connect to Your VPS Begin by connecting to your EcoStack Cloud VPS using SSH. Replace `your-username` and `your-vps-ip` with your actual username and VPS IP address. ```bash ssh your-username@your-vps-ip ``` ##### Step 2: Import the MongoDB Public Key To ensure that the packages are authentic, import MongoDB’s public GPG key: ```bash wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | sudo apt-key add - ``` ##### Step 3: Add MongoDB Repository Add the MongoDB repository to your system's package source list: ```bash echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-6.0.list ``` ##### Step 4: Update the Package Index Refresh your package database to include the MongoDB repository: ```bash sudo apt update ``` ##### Step 5: Install MongoDB Install the MongoDB packages: ```bash sudo apt install -y mongodb-org ``` ##### Step 6: Start and Enable MongoDB Start the MongoDB service and ensure it starts on boot: ```bash sudo systemctl start mongod sudo systemctl enable mongod ``` Check the status of MongoDB to confirm it’s running: ```bash sudo systemctl status mongod ``` ##### Step 7: Secure MongoDB By default, MongoDB is configured to allow connections only from localhost. For additional security, you should enable authentication and create an administrative user. - **Edit MongoDB configuration file**: ```bash sudo nano /etc/mongod.conf ``` - **Uncomment the `security` section** and enable authorization by adding the following lines: ```yaml security: authorization: enabled ``` - **Restart MongoDB** to apply the changes: ```bash sudo systemctl restart mongod ``` - **Access the MongoDB shell** to create an admin user: ```bash mongo ``` Switch to the `admin` database: ```javascript use admin ``` Create a new administrative user. Replace `admin` and `strongpassword` with your desired username and password: ```javascript db.createUser({ user: "admin", pwd: "strongpassword", roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] }) ``` - **Exit the MongoDB shell**: ```javascript exit ``` - **Verify that authentication is working** by connecting to MongoDB with the new admin user: ```bash mongo -u admin -p --authenticationDatabase admin ``` Enter your password when prompted. You should see the MongoDB shell prompt if authentication is successful. ##### Step 8: Enable Remote Access (Optional) If you need to allow remote access to MongoDB, edit the MongoDB configuration file: ```bash sudo nano /etc/mongod.conf ``` - **Bind MongoDB to all IP addresses** by changing the `bindIp` option under the `net` section. Replace `127.0.0.1` with `0.0.0.0`: ```yaml net: bindIp: 0.0.0.0 ``` - **Restart MongoDB** to apply the changes: ```bash sudo systemctl restart mongod ``` Ensure that your firewall is configured to allow incoming connections on MongoDB’s default port (27017). With `ufw`, you can allow specific IP addresses: ```bash sudo ufw allow from to any port 27017 ``` Replace `` with the IP address you want to allow. ##### Step 9: Test MongoDB Connection Test your MongoDB setup by connecting from a remote machine. Use a MongoDB client like `mongo` or any GUI client that supports MongoDB. Replace `your-vps-ip` with your server’s IP address: ```bash mongo -u admin -p --authenticationDatabase admin --host your-vps-ip --port 27017 ``` Enter your password when prompted. You should be able to connect to your MongoDB server. ##### Step 10: Backup and Restore MongoDB Databases (Optional) To back up your MongoDB databases, use the `mongodump` utility: ```bash mongodump --out /path/to/backup ``` To restore a MongoDB database from a backup, use the `mongorestore` utility: ```bash mongorestore /path/to/backup ``` #### Conclusion You have successfully installed and secured MongoDB on Ubuntu Server 22.04.
