In addition to previously provided answers, one option is to follow the 'localhost exception' approach to create the first user if your db is already started with access control (--auth switch). In order to do that, you need to have localhost access to the server and then run:

mongo
use admin
db.createUser(
 {
     user: "user_name",
     pwd: "user_pass",
     roles: [
           { role: "userAdminAnyDatabase", db: "admin" },
           { role: "readWriteAnyDatabase", db: "admin" },
           { role: "dbAdminAnyDatabase", db: "admin" }
        ]
 })

As stated in MongoDB documentation:

The localhost exception allows you to enable access control and then create the first user in the system. With the localhost exception, after you enable access control, connect to the localhost interface and create the first user in the admin database. The first user must have privileges to create other users, such as a user with the userAdmin or userAdminAnyDatabase role. Connections using the localhost exception only have access to create the first user on the admin database.

Here is the link to that section of the docs.

By default mongodb has no enabled access control  so there is no default user or password    To enable access control  use either the command line option --auth or security authorization configuration file setting   You can use the following procedure or refer to Enabling Auth in the MongoDB docs   Procedure   Start MongoDB without access control   mongod --port 27017 --dbpath  data db1  Connect to the instance   mongo --port 27017  Create the user administrator   use admin db createUser          user   myUserAdmin       pwd   abc123       roles      role   userAdminAnyDatabase   db   admin             Re-start the MongoDB instance with access control   mongod --auth --port 27017 --dbpath  data db1  Authenticate as the user administrator   mongo --port 27017 -u  myUserAdmin  -p  abc123      --authenticationDatabase  admin

In addition with what  Camilo Silva already mentioned  if you want to give free access to create databases  read  write databases  etc  but you don t want to create a root role  you can change the 3rd step with the following    use admin db createUser          user   myUserAdmin       pwd   abc123       roles      role   userAdminAnyDatabase   db   admin                     role   dbAdminAnyDatabase   db   admin                     role   readWriteAnyDatabase   db   admin
