Start MongoDB without access control.

mongod --port 27017 --dbpath /data/db1

Connect to the instance.

For example, connect a mongo shell to the instance.

mongo --port 27017

Create the user administrator.

In the admin database, add a user with the userAdminAnyDatabase role. For example, the following creates the user myUserAdmin in the admin database:

use admin

db.createUser(

  {

    user: "myUserAdmin",

    pwd: "abc123",

    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]

  }

)

restart mongodb instance

mongod --auth --port 27017 --dbpath /data/db1

mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"
