MongoDB installation and configuration

In case you face any issues, refer official docs

Installing mongodb v4.4

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

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

b. Create a list file for MongoDB

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

c. Reload local package database.

sudo apt-get update

d. Install the MongoDB packages

sudo apt-get install -y mongodb-org

e. Optional. Although you can specify any available version of MongoDB

echo "mongodb-org hold" | sudo dpkg --set-selections
echo "mongodb-org-server hold" | sudo dpkg --set-selections
echo "mongodb-org-shell hold" | sudo dpkg --set-selections
echo "mongodb-org-mongos hold" | sudo dpkg --set-selections
echo "mongodb-org-tools hold" | sudo dpkg --set-selections

Configure mongodb

a. Create a directory to store data

sudo mkdir /data
sudo mkdir /data/db

b. Grant required permissions

sudo chown -R `id -un` /data/db

Start mongodb services

# start mongodb service
sudo service mongod start
# Check status of the service
sudo service mongod status

Initialize MongoDB

sudo mongod

The above command will start a MongoDB instance running on your local machine. I will pick a port to run the database, possibly it will be 27017, so your db will be hosted at

mongodb://localhost:27017/

MongoDB shell

Here you can execute your db queries. Initialize the shell by following command

mongo
