Introduction to MongoDB Administration

MongoDB is a NoSQL document database that stores data in flexible, JSON-like documents. It allows for high availability, scalability, and performance.

Key Features:

• Document-oriented storage
• High scalability
• Rich query language
• Support for ACID transactions

To install MongoDB, follow these steps:

1. Download the MongoDB installer from the MongoDB Download Center.
2. Run the installer and follow the installation instructions.
3. Verify the installation by running the following command in your terminal:

mongo --version

MongoDB configurations can be managed through the mongod.conf file. Here are key settings:

• storage: Define data storage options and directories.
• systemLog: Configure logging settings.
• net: Set network interfaces and ports.

Example Configuration:

# mongod.conf
storage:
  dbPath: /var/lib/mongo
systemLog:
  destination: file
  path: /var/log/mongodb/mongod.log
net:
  bindIp: 127.0.0.1
  port: 27017

To backup and restore MongoDB databases, you can use the following commands:

# Backup
mongodump --db yourDatabase --out /path/to/backup

# Restore
mongorestore --db yourDatabase /path/to/backup/yourDatabase

Monitoring MongoDB involves checking performance metrics and logs. Use the following tools:

• MongoDB Compass: GUI for monitoring and visualizing data.
• MongoDB Atlas: Cloud-based monitoring and performance optimization.
• Command-Line Tools: Use commands like db.serverStatus() to check server health.
