wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo systemctl start mongod
sudo systemctl status mongod

Setup authentication for mongodb (optional)

Refer.

Open a mongo shell with - mongosh

Run the following in the mongo shell

  use admin
  db.createUser(
    {
      user: "myUserAdmin",
      pwd: "myPassword", // or cleartext password
      roles: [ { role: "userAdminAnyDatabase", db: "admin" }, "readWriteAnyDatabase" ]
    }
  )
  db.adminCommand( { shutdown: 1 } )

Exit mongosh with Crtl+ C and run the following in a normal shell

sudo nano /etc/mongod.conf
# add the following lines ###########
security
  authentication: enabled
#####################################
sudo systemctl restart mongod

# how to connect after enabling auth
mongosh --port 27017 --authenticationDatabase "admin" -u "myUserAdmin" -p "myPassword"
# change mongodb URL in the server config too

In case of errors try the following

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock
sudo service mongod restart
sudo systemctl status mongod
