What this article shares to you is about the authentication methods in Mongodb, which the editor thinks is very practical, so I share it with you to learn. I hope you can get something after reading this article.

1. Introduction

No matter how secure the database is or the local environment, it is necessary to establish a secure environment for the database.

Mongodb provides a series of security features, and here is a very common authentication method.

two。 Turn on verification

By default, as long as the-- auth option is not added when starting the database, there is no authentication function, and all clients can operate with all permissions.

If added, we can connect to the database through secure authentication. If you want to authenticate in the database, you can use db.auth (username, password), and return 1 if the authentication is successful, and vice versa.

3. Establish a user

To create a user, we can create a user through the db.createUser () method, such as the following:

Db.createUser ({user: 'username', pwd:' password', roles: [{role: 'read', db:' test'}]})

The db.createUser method accepts an object in which user represents the user name and pwd represents the password, while roles is an array that can accept multiple objects, each of which can correspond to the database in which the role field represents the permissions on the database. Officially, some columns have built-in roles that can be queried through documents.

4. Delete user

To delete a user, you need a user with permission to do so. Use the db.dropUser () method to accept a string, which is the user name:

Db.dropUser ('user1')

5. Get users

You can get user information through the db.getUser () method, which also accepts a string that is the user name:

Db.getUser ('user1')

These are the authentication methods in Mongodb, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
