A brief analysis of MONGODB user management

1. Create a Super User

use admindb.createUser(  { user: "adminUserName", pwd: "userPassword", roles: [ { roles: "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

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

3. View the permissions of the current user

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

4. Create a general user, also use CreateUser

 use db01db< Span class= "Hljs-class" >.createuser ({ user: "OneUser", Pwd: "12345", roles:[{role: "read", Db:{role: "read", Db: "DB02"}, { role: " Read ", Db:" DB03 "}]})           

5. Create a superuser who is not restricted by access

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

6. Change the password

use admindb.changeUserPassword("username", "xxx")

7. View user Information

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

8. Change Password and user information

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.
