Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

4.显示数据库

> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB

5.选择使用admin库

> use admin
switched to db admin

6.创建用户

>db.createUser( {user: "root",pwd: "root",roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]})

Successfully added user: {
        "user" : "root",
        "roles" : [
                {
                        "role" : "userAdminAnyDatabase",
                        "db" : "admin"
                }
        ]
}

mongodb中的用户是基于身份role的；
管理员账户的 role：userAdminAnyDatabase；
'userAdmin'：代表用户管理身份；
'AnyDatabase'：代表可以管理任何数据库；

7.第二次进入

> use admin
switched to db admin
> db
admin
>  db.auth("root", "root")

>  db.auth("root", "roo1t")
Error: Authentication failed.
