How to secure MongoDB with username and password

start mongo shell by typing mongo in terminal.
use admin database:

use admin

create a new user and assign your intended role:

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

exit mongo and add the following line to etc/mongod.conf:

security:
    authorization: enabled

restart mongodb server

(optional) 6.If you want your user to have root access you can either specify it when creating your user like:

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

or you can change user role using:

db.auth("myUserAdmin", "abc123")
db.grantRolesToUser('myUserAdmin', [{ role: 'root', db: 'admin' }])

MongoDB loads but breaks, returning status=14

Solution 1 :

fter googling around for a while. I found that that is because the permission settings on /var/lib/mongodb and /tmp/mongodb-27017.lock are wrong. You will have to change the owner to monogdb user

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

then

sudo systemctl restart mongod

sudo systemctl start mongod

sudo systemctl status mongod

sudo systemctl enable mongod

Solution 2:
deleting the mongod sock file solved the issue for me sudo rm -rf /tmp/mongodb-27017.sock then start again sudo systemctl start mongod

By using this my error was gone:

Go to the TMP directory: cd /tmp
Check if you have the mongodb sock file: ls *.sock
Change the user:group permission: chown mongodb:mongodb
Start MongoDB: sudo systemctl start mongod
Check the MongoDB status: sudo systemctl status mongod
