User Management for MongoDB

Introduction: Because the user management of MongoDB data is based on the management of a single library, his management strategy is probably as follows

If you verify the account of the Admin library, all libraries are accessible

If an account with a non-admin library is validated, this permission can only access the data under the current library

Suggested steps:

If you want to set the database account, it is best that we do not start the database validation, and then go to the Admin library, create a password

Exit Add -auth Verify restart MongoDB and then use the Admin library account to authenticate, if you go to another library for account creation, and then re-login after completion to verify

Verify the following:

Start Mongod

Mongod.exe--dbpath=e:\mongodb\db-auth -auth user authentication is turned on, user authentication will fail if startup does not add this parameter

First enter the Admin library

Use admin

Users viewing the current data

Show collections can return two tables

The SA account password for the Add Admin Library is SA

Db.adduser (' sa ', ' sa ')

CTRL + C exits the current login

Log back in and go to the Admin Library and test Library to check if you can query the current table

> Use adminswitched to DB admin> show Collectionsmon Oct 17:11:01 uncaught exception:error: {"$err": "U nauthorized db:admin lock Type:-1 client:127.0.0.1 "," code ": 10057}> use testswitched to DB admin> show Coll Ectionsmon Oct 17:13:51 uncaught exception:error: {"$err": "Unauthorized db:test lock type:-1 client:127.0.0. 1 "," Code ": 10057}

Verify that the SA account in the Admin Library is able to view information from the Admin Library and test Library

> Db.auth (' sa ', ' sa ') 1> show collectionssystem.indexessystem.users> use testswitched to DB test> show Collectionssystem.indexessystem.users>

Enter the test library and create the user test password test

> Use testswitched to DB test> db.adduser (' Test ', ' test ') {"updatedexisting": True, "n": 1, "C Onnectionid ": Ten," err ": null," OK ": 1}{" _id ": ObjectId (" 543b80be1d60b11044c2fc59 ")," use R ":" Test "," readOnly ": false," pwd ":" A6de521abefc2fed4f5876855a3484f5 "}>

CTRL + C Exit login again to verify that the test account has access to the test library and the admin library

> Db.auth (' Test ', ' Test ') 1> show collectionssystem.indexessystem.users> use adminswitched to DB admin> show Collectionsmon Oct 17:21:06 uncaught exception:error: {"$err": "Unauthorized db:admin lock Type:-1 client:127 .0.0.1 "," Code ": 10057}>

Verify the Admin admin account to see if you can view the Admin library information

> Use adminswitched to DB admin> db.auth (' sa ', ' sa ') 1> show collectionssystem.indexessystem.users>

PS: When authenticating a user, if return 1 proves to have this user, if return 0 proves that there is no such user as:

> Use adminswitched to DB admin> db.auth (' sa ', ' sa ') 1
