MongoDB: Server has startup warnings ''Access control is not enabled for the database'' - Stack Overflow

Mongodb v3.4
You need to do the following to create a secure database:
Make sure the user starting the process has permissions and that the directories exist (/data/db in this case).
1) Start MongoDB without access control.
mongod --port 27017 --dbpath /data/db
2) Connect to the instance.
mongo --port 27017
3) Create the user administrator (in the admin authentication database).
use admin
db.createUser({user: "myUserAdmin",pwd: "abc123",roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]}
)
4) Re-start the MongoDB instance with access control.
mongod --auth --port 27017 --dbpath /data/db
5) Connect and authenticate as the user administrator.
mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"
6) Create additional users as needed for your deployment (e.g. in the test authentication database).
use test
db.createUser({user: "myTester",pwd: "xyz123",roles: [ { role: "readWrite", db: "test" },{ role: "read", db: "reporting" } ]}
)
7) Connect and authenticate as myTester.
mongo --port 27017 -u "myTester" -p "xyz123" --authenticationDatabase "test"
I basically just explained the short version of the official docs here: https://docs.mongodb.com/master/tutorial/enable-authentication/
