Question

I am using mongoDB Cluster with version 3.4 in google cloud compute engine, actually past week my database got attacked by hackers that\'s why i thought about using authorizatio

Answer 1

To be able to create a new user, you need to first disable security in /etc/mongod.conf

// security: // authorization: enabled Then restart Mongodb server sudo service mongo restart

After this you can add the user and role that you want from the shell.

db.createUser({ user: 'test_user', pwd: 'test', roles: [ { role: "userAdmin", db: "test" }, { role: "dbAdmin", db: "test" }, { role: "readWrite", db: "test" } ] })

To enable authenticated connection Uncomment the line again in /etc/mongod.conf

security: authorization: enabled and restart the server again
