What is MongoDB?

• As per Wikipedia
• MongoDB is a cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas. MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License (SSPL).

Install MongoDB Community Edition

Step 1

• Import the public key used by the package management system.

  $ wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -

  The operation should respond with an OK.

• However, if you receive an error indicating that gnupg is not installed, you can
• Install gnupg and its required libraries using the following command:

  $ sudo apt-get install gnupg

• Once installed, retry importing the key

  $ wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -

Step 2

• Create a list file for MongoDB
• Create the list file /etc/apt/sources.list.d/mongodb-org-4.2.list for your version of Ubuntu.

  $ sudo touch /etc/apt/sources.list.d/mongodb-org-4.2

Step 3

• Copy the command and paste it in the terminal as this will pull the packages to install MongoDB

  	$ echo "deb [ arch=amd64,arm64 ]
  	https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list

Step 4

• Reload local package database

  $ sudo apt-get update

Step 5

• Install the MongoDB packages

  $ sudo apt-get install -y mongodb-org

Step 6

• Start MongoDB.

  $ sudo systemctl start mongod

• If you receive an error similar to the following when starting mongod. Failed to start mongod.service: Unit mongod.service not found.
• Run the following command

  $ sudo systemctl daemon-reload

Step 7

• Verify that MongoDB has started successfully

  $ sudo systemctl status mongod

Step 8

• You can optionally ensure that MongoDB will start following a system reboot by issuing the following command

  $ sudo systemctl enable mongod

Step 9 (Optional)

• Stop MongoDB

  $ sudo systemctl stop mongod

Step 10 (Optional)

• Restart MongoDB

  $ sudo systemctl restart mongod

Uninstall MongoDB Community Edition

Step 11

• Stop MongoDB

  $ sudo service mongod stop

Step 12

• Remove Packages

  $ sudo apt-get purge mongodb-org*

Allow Remote Connections to MongoDB in Ubuntu

• In Linux, including Ubuntu, bindIp is by default set to 127.0.0.1 in /etc/mongod.conf. This means the mongod process only listens on the local loopback interface.
• If you set the value of the bindIp to 0.0.0.0 or remove the bindIp option, mongod process will listen on all interfaces.

  	# network interfaces
  	net:
  	port: 27017
  	bindIp: 0.0.0.0
  	

• Or we can bind mongod process to a specific IP Address

  	# network interfaces
  	net:
  	port: 27017
  	bindIp: 192.168.1.100
  	

• To bind to multiple IP addresses, enter a list of comma-separated IP addresses

  	# network interfaces
  	net:
  	port: 27017
  	bindIp: 127.0.0.1,192.168.1.100	
  	

• Note: When you complete editing the configuration file just reload the demon this will apply the changes and restart the mongod service

  	$ sudo systemctl daemon-reload
  	$ sudo systemctl restart mongod
