User management

User Management of mongodb

Note:

A) in mongodb, there is an admin database, which involves server configuration operations, so you need to switch to admin data first.

That is, use admin,-- > is equivalent to entering superuser management mode.

B) mongo users are built on a database basis, and each database has its own administrator.

C) when we set up users, we need to first set up an administrator under the admin database-after this administrator logs in, it is equivalent to a super administrator.

0: view users

1: add user

Command: db.addUser ()

Simple parameter: db.addUser (username, password, read-only)

Note: after adding users, we log out and log in again and find that we can still read the database directly.

Reason: when the mongodb server starts, authentication is not required by default.

For the user to take effect, specify the-- auth option when you need to start the server.

In this way, authentication is needed when operating.

Then it will be restricted:

Enter the account password to pass the verification:

Example:

1: add user

Use admin

Db.addUser ('sa','sa',false)

2: authentication

Use test

Db.auth (username, password)

3: change the user's password

Use test

Db.changeUserPassword (user name, new password)

4: delete the user

Use test

Db.removeUser (user name)

Note: if you need to add more permissions to the user, you can use the json structure to pass the user parameters

Example:

Use test

Db.addUser ({user:'guan',pwd:'111111',roles: ['readWrite,dbAdmin']})
