How to Install MongoDB on AnonVM: A Complete Guide

MongoDB is one of the most popular NoSQL databases, known for its high performance, scalability, and flexibility with unstructured data. If you’re hosting your application on an AnonVM server, MongoDB can provide the perfect solution for handling large-scale, high-availability database requirements. This guide will walk you through installing MongoDB on your AnonVM server, optimizing it for performance and security.

Prerequisites

Before you begin, ensure the following:

• A VPS or Dedicated Server: Hosted on AnonVM for offshore privacy and security.
• Root/Sudo Access: You need root or sudo privileges to install and configure MongoDB.
• Linux-based OS: This guide is optimized for Ubuntu/Debian-based or CentOS operating systems.

Step 1: Update Your System

Begin by ensuring your system is fully updated:

For Ubuntu/Debian-based systems:

For CentOS-based systems:

Step 2: Install MongoDB

Install MongoDB on Ubuntu/Debian

1. Import the MongoDB public key to verify the installation package:

    

   wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | sudo tee /etc/apt/trusted.gpg.d/mongodb.asc

2. Create the MongoDB repository file for your version of Ubuntu/Debian:

    

   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

3. Update your package database:

    

   sudo apt update

4. Install MongoDB:

    

   sudo apt install -y mongodb-org

Install MongoDB on CentOS

1. Add the MongoDB repository:

    

   echo "[mongodb-org-6.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/amazon/2/mongodb-org/6.0/x86_64/ gpgcheck=1 enabled=1" | sudo tee /etc/yum.repos.d/mongodb-org-6.0.repo

2. Install MongoDB:

    

   sudo yum install -y mongodb-org

Step 3: Start MongoDB

After the installation completes, start the MongoDB service:

To ensure that MongoDB starts on boot, enable the service:

Step 4: Secure MongoDB

MongoDB runs without authentication by default, meaning anyone with access to your server could access your database. It's critical to secure it by enabling authentication.

1. Edit the MongoDB configuration file to enable authentication:

    

   sudo nano /etc/mongod.conf

   In the file, look for the security section, and add the following:

    

   security: authorization: "enabled"

2. Restart MongoDB to apply the changes:

    

   sudo systemctl restart mongod

3. Create an administrative user: First, connect to MongoDB using the mongo shell:

    

   mongo

   Then, create the admin user:

    

   use admin db.createUser({ user: "admin", pwd: "your_secure_password", roles: [ { role: "root", db: "admin" } ] });

4. Exit the MongoDB shell:

    

   exit

5. Now, restart MongoDB again to enforce authentication:

    

   sudo systemctl restart mongod

6. Access MongoDB with the new user:

    

   mongo -u admin -p --authenticationDatabase admin

Step 5: Configure Firewall (If Applicable)

If your AnonVM server has a firewall, make sure to allow traffic on the default MongoDB port (27017).

For Ubuntu/Debian-based systems:

For CentOS-based systems (using firewalld):

Step 6: Configure MongoDB for Performance

MongoDB can be optimized for performance by adjusting a few configuration settings. To configure these settings, open the configuration file:

Here are some key parameters to optimize:

1. wiredTigerCacheSizeGB: If you have a large amount of memory (RAM), increasing the cache size can improve performance. For example, if your server has 16GB of RAM, you can set the cache size to 2GB:

    

   storage: wiredTiger: engineConfig: cacheSizeGB: 2

2. noIndexBuildRetry: Enable this setting to ensure that MongoDB doesn’t retry index builds after a failure (useful for large databases):

    

   setParameter: noIndexBuildRetry: true

3. bindIp: By default, MongoDB binds to 127.0.0.1 for security reasons. If you need to access MongoDB remotely, change this setting to the IP address of your server (or use 0.0.0.0 to allow access from all IPs, though this is less secure):

    

   net: bindIp: 0.0.0.0

4. Increase the number of allowed connections if your application requires high concurrency:

    

   net: maxIncomingConnections: 10000

After making changes, restart MongoDB:

Step 7: Backup and Restore MongoDB

To ensure that your data is safe, you should regularly back up your MongoDB databases.

Backup MongoDB:

Use mongodump to create a backup of your database:

Restore MongoDB:

To restore a backup:

Step 8: Monitor MongoDB Performance

Monitoring is essential for maintaining optimal database performance. You can use MongoDB Monitoring Service (MMS) or other third-party tools like Prometheus and Grafana to keep track of database performance metrics.

Conclusion

By following these steps, you've successfully installed and configured MongoDB on your AnonVM server. MongoDB is now secure, optimized for performance, and ready for use in your applications.

Key Takeaways:

• MongoDB is ideal for applications requiring high scalability and flexible schema design.
• Securing MongoDB by enabling authentication is crucial for protecting sensitive data.
• Performance tuning and regular backups are key to maintaining a healthy database.
• Monitoring tools help in proactive management of database performance.
