Little recently touched MongoDB, so here we start to learn MongoDB, user management module related content.

Enter Shell for MongoDB

Enter the following command here to enter shell of MongoDB

mongo

Switching databases

use admin

Use the command above to switch the database to the admin database.

Create a super administrator user

Create a user with super administrator privileges

db.createUser(
 { user: "admin",
  customData : {description:"superuser"},
  pwd: "admin",
  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
 }
)

Each of these fields is explained below

user field: Name of the new user. The password for the pwd field user cusomData field, any content, can be the user name of the national introduction. The roles field specifies the user’s role, which is used for an empty array. In the roles field, you can specify the relevant role. The name of the db database used to manage the database.

Create a superuser

Create a superuser here to manage the permissions of all users

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

Create 1 business database administrator user

This user is specifically responsible for the addition, deletion, and modification of one or more databases.

> db.createUser({
  user:"user001",
  pwd:"123456",
  customData:{
    name:'jim',
    email:'[email protected]',
    age:18,
  },
  roles:[
    {role:"readWrite",db:"db001"},
    {role:"readWrite",db:"db002"},
    'read'//  You have read-only access to other databases, right db001 , db002 Is read and write permission
  ]
})

Among them

Database user roles, read, readWrite. Database administration roles: dbAdmin, dbOwner, userAdmin Cluster management roles: clusterAdmin, clusterManager, clusterMonitor, hostManage. Backup and restore roles: backup, restore. All database roles: readAnyDatabase. readWriteAnyDatabase, userAdminAnyDatabase, dbAdminAnyDatabase. Superuser role: root Internal role _system
