curl -fsSL https://www.mongodb.org/static/pgp/server-8.0.asc | sudo gpg -o /usr/share/keyrings/mongodb-server-8.0.gpg --dearmor


echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-8.0.gpg ] https://repo.mongodb.org/apt/ubuntu noble/mongodb-org/8.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-8.0.list

apt-get update 

sudo apt install -y mongodb-org

sudo systemctl start mongod
sudo systemctl enable mongod
sudo systemctl status mongod

Test connection with

mongosh --eval 'db.runCommand({ connectionStatus: 1 })'

Do some stuff to show working

mongosh
use test_db
db.files.insert({"name":"rap"})
db.dropDatabase()

Configure Mongo

Create Admin User

Enter the shell

mongosh

Then use this command changed appropriately

db.createUser({
  user: "new_admin",
  pwd: "not_saying",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } , "readWriteAnyDatabase" ]
})

Then exit shell

exit

Configure Security and IP

In /etc/mongod.conf add

security:
  authorization: enabled

Also in /etc/mongod.conf change if you want to

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1, 192.168.1.70

Restart the service

sudo systemctl restart mongod

Test listening

Now the admin user works

mongosh -u bibble_admin -p --authenticationDatabase admin
use admin
db.getUsers();

Create general user

Start the cli interface with

 pwd: "password",
 roles:[{role: "userAdmin" , db:"CatalogDb"}]
})

// Grant a role
db.grantRolesToUser( "mongoadmin", [  {role: "readWrite", db: "CatalogDb"} ] )
