MongoDB User Management

1. Create a Super User

?

1234567891011121314

use admin db.createUser(   {     user: "adminUserName",     pwd: "userPassword",     roles:     [       {         role: "userAdminAnyDatabase",         db: "admin"      }     ]   } )

There are two types of superuser role, useradmin or useradminanydatabase (more access to all databases than the previous one).

DB is the name of the specified database, and admin is the management database.

2. Log in with the newly created user

?

1	mongo --host xxx -u adminUserName -p userPassword --authenticationDatabase admin

3. View the permissions of the current user

?

123456

db.runCommand(   {     usersInfo:"userName",     showPrivileges:true   } )

4. Create a general user, also use CreateUser

?

123456789101112

use db01 db.createUser(   {     user:"oneUser",     pwd:"12345",     roles:[       {role:"read",db:"db01"},       {role:"read",db:"db02"},       {role:"read",db:"db03"}     ]   } )

5. Create a superuser who is not restricted by access

?

12345678

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

6. Change the password

?

12	use admin db.changeUserPassword("username", "xxx")

7. View user Information

?

1	db.runCommand({usersInfo:"userName"})

8. Change Password and user information

?

1234567

db.runCommand(   {     updateUser:"username",     pwd:"xxx",     customData:{title:"xxx"}   } )

Note:

1. and user management related operations are basically to run under the Admin database, to use the admin first;

2. If under a single database, it can only operate on the permissions of the current database;

3. Db.adduser is an older version of the operation, now the version can also continue to use, created by the user is a root role of the Super administrator.
