Mongovue is unable to create collections and log in with user name and password

Geeks, please accept the hero post of 2021 Microsoft x Intel hacking contest>>>

1: Mongovue was unable to create collections

The new storage engine of mongodb is wiredtiger. Under this storage engine, we can’t see the collection with the visualization tool mongovue. We should replace it with mmapv1 engine

1. Delete the data folder and recreate the data folder

2. Next, execute mongod — storageengine mmapv1 — dbpath D::?Office?Mongodb?Data

2: Mongovue cannot log in with user name and password

There are two authentication mechanisms in mongodb: scrum-sha-1 and mongodb-cr. After version 3.0, the default is: scrum-sha-1; 2. Spring mongodb defaults to mongodb-cr and does not support setting authentication mode; Solution: modify the authentication method of mongodb

1. View auth authentication method

use admin

db.system.version.findOne({“_ id”:”authSchema”})

(return to {“_ id” : “authSchema”, “currentVersion” : 3 } currentVersion 3:MONGODB-CR currentVersion 5:SCRAM-SHA-1)

2. Delete all previously set users


3. Delete the original auth authentication method and set it to mongodb-cr


db.system.version.insert({“_ id”:”authSchema”,”currentVersion”:3})

4. Add admin user again (super administrator)

use admin


5. Create a new test database and set users and roles (permissions) for the test database

use test


3: The admin library cannot view collections

Change the role to readwriteanydatabase


4: Enable user authentication

Method 1: on the command line, enter mongod — auth — logpath “D: office, mongodb, log. Mongod. Log” — dbpath “D: office, mongodb, data” — reinstall
method 2: on the command line, enter mongod — dbpath “D: office, mongodb, data” — logpath “D: office, mongodb, log. Mongod. Log” — auth

5: Turn off user authentication

mongod –logpath “D:\office\MongoDB\log.mongod.log” –dbpath “D:\office\MongoDB\data” –reinstall

7: Forget the password

Once you forget the admin password, you can turn off user authentication, delete the user and recreate it

6: Login


2:use admin
