MongoDB is a free and open-source document-oriented database that uses JSON-like documents with optional schemas to store information. It designed with both scalability and developer agility in mind.
MongoDB is a cross-platform database and is available for Windows, Linux, OS X, Solaris, and FreeBSD. It is released under Server Side Public License (SSPL).
Here, we will see how to install MongoDB on Ubuntu 20.04.
Add MongoDB Repository
MongoDB Inc releases stable packages for Ubuntu operating systems and shares them via their repository. MongoDB packages available in MongoDB repository are generally fresher than those in the Ubuntu repositories.
You should always use the official MongoDB packages.
Install the below dependent packages.
sudo apt update sudo apt install -y gnupg
Add the MongoDB’s official repository to the system.
wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add - echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
Install MongoDB
Update the repository index.
sudo apt update
Install the MongoDB using the apt command.
sudo apt install -y mongodb-org
Post Installation
Network Binding
By default, MongoDB listens on to 127.0.0.1, a localhost network interface. This means that MongoDB can only accept connections from clients that are running on the same machine. In this case, remote clients will not be able to connect to the MongoDB.
sudo nano /etc/mongod.conf
Update the bindIP with your system IP address.
# network interfaces
net:
port: 27017
bindIp: 192.168.0.10
Security CheckList
Create Admin User
By default, MongoDB doesn’t authenticate users to read and modify data, and it is the biggest security concern. To enable authentication, first, create a database administrative user.
Access Control
After creating an administrative user, enable access control to enforce authentication. This setting allows only identified users to perform actions based on their roles.
sudo nano /etc/mongod.conf
Add the below lines.
security: authorization: enabled
Manage MongoDB Service
To start MongoDB service, run:
sudo systemctl start mongod
To enable MongoDB service to start automatically at the system startup run:
sudo systemctl enable mongod
Check the status of MongoDB service.
sudo systemctl status mongod
Output:
● mongod.service - MongoDB Database Server Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2020-08-03 13:30:55 EDT; 7s ago Docs: https://docs.mongodb.org/manual Main PID: 4392 (mongod) Memory: 61.1M CGroup: /system.slice/mongod.service └─4392 /usr/bin/mongod --config /etc/mongod.conf Aug 03 13:30:55 ubuntu2004 systemd[1]: Started MongoDB Database Server.
