mongo password settings

MongoDB version v4.0.7

System Win10

　note:

　　　　　　To create a user for the database, you must first switch to the appropriate database:

# First switching 
use database name; 

# then create 
db.createUser ({})

Super Admin

Set admin (for admin password at the library)

use.admin   
db.createUser ({ 
  User: ' ADMIN ' , // username 
  pwd: ' 123456 ' , // Password 
  Roles: [{ 
    Role: ' the root ' , // Roles 
    DB: ' ADMIN '   // database 
  }] 
})

Setup is complete, you can enter show usersto see if the setting is successful.

Open the verification

MongoDB find installation directory, open mongodb.conf file, locate the following sentence

authu=true

Restart MongoDB

kill -9 mongo process ID 
./mongod -f mongodb.conf

or:

Close 
the mongod --journal --shutdown -f / usr / local / MongoDB / bin / mongodb.conf 
start 
the mongod --journal -f /usr/local/mongodb/bin/mongodb.conf

Task Manager Interface

Find MongoDB service, right restarted.

At this time, we can open the powershell connect to the database:

Input mongo:

Show a successful connection, but when we enter other instructions are not prompted to no authority but does not perform:

Log database

// embodiment a 
Mongo 
use ADMIN 
db.auth ( ' ADMIN ' , ' 123456 ' )

 // Second way 
Mongo ADMIN -u ADMIN -p 123456

This time we can properly access and manipulate the data.

Adding database users

Apart from the super administrator can set up the database, you also can set up a separate administrator for each database. Its only operating authority must separate the data.

use test  // 跳转到需要添加用户的数据库
db.createUser({ user: 'mts', // 用户名 pwd: '123456', // 密码 roles:[{ role: 'readWrite', // 角色 db: 'qidatas' // 数据库名 }] })

Common Commands

show users  // 查看当前库下的用户

db.dropUser('testadmin')  // 删除用户

db.updateUser('admin', {pwd: '654321'})  // 修改用户密码

db.auth('admin', '654321')  // 密码认证
