數據庫操作權限

readAnyDatabase    任何數據庫的只讀權限
userAdminAnyDatabase    任何數據庫的讀寫權限
userAdminAnyDatabase    任何數據庫用戶的管理權限
dbAdminAnyDatabase    任何數據庫的管理權限

啟動客戶端：

cd /usr/local/mongodb/
./mongo

查看一下用戶表有沒有數據

db.system.users.find()

查看用戶

> show users

MongoDB創建數據庫管理員用戶

# 切換至admin數據庫。
# 也可以使用db 
 
= db.getSiblingDB(‘admin‘)代替use admin。
use admin
 
# 創建管理員用戶，並指定其權限。
db.createUser({
  user : ‘root‘,
  pwd : ‘123456‘,
  roles : [
    ‘clusterAdmin‘,
    ‘dbAdminAnyDatabase‘,
    ‘userAdminAnyDatabase‘,
    ‘readWriteAnyDatabase‘
  ]
})

輸出

> db.createUser({
...   user : ‘root‘,
...   pwd : ‘
 
123456‘,
...   roles : [
...     ‘clusterAdmin‘,
...     ‘dbAdminAnyDatabase‘,
...     ‘userAdminAnyDatabase‘,
...     ‘readWriteAnyDatabase‘
...   ]
... })
Successfully added user: {
    "user" : "root",
    "roles" : [
        "clusterAdmin",
        "dbAdminAnyDatabase",
        "userAdminAnyDatabase
 
",
        "readWriteAnyDatabase"
    ]
}

重啟MongoDB服務並加上--auth參數

./mongod --dbpath=/usr/local/mongodb/data --logpath=/usr/local/mongodb/logs --logappend  --port=27017 --fork --auth

查看用戶，會報錯

> use admin
switched to db admin
> show users
2019-02-15T15:20:52.250+0800 E QUERY    [js] Error: command usersInfo requires authentication :

此時需要認證

> db.auth(‘root‘,‘123456‘)
1

查看用戶，就可以看到了

> show users

    "_id" : "admin.root",
    "user" : "root",
    "db" : "admin",
    "roles" : [

建立普通帳號

用戶user

db.createUser(
{user:‘user‘,
 pwd:‘123456‘, 
 roles:[
   {role:‘readWrite‘, db:‘userdb‘}
]
})

輸出

> db.createUser(
... {user:‘user‘,
...  pwd:‘123456‘, 
...  roles:[
...    {role:‘readWrite‘, db:‘userdb‘}
... ]
... })
Successfully added user: {
    "user" : "user",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "userdb"
        }
    ]
}

用戶user1

db.createUser(
{user:‘user1‘,
 pwd:‘123456‘, 
 roles:[
   {role:‘root‘, db:‘userdb‘}
]
})

接下來，為指定數據庫創建一般用戶角色，用於程序讀取、修改數據庫。

假如現有blog數據庫，要為其創建用戶名為admin、密碼為123456，擁有CRUD（增查改刪）權限，指令如下：

# 切換至blog數據庫。
use blog
 
# 創建admin用戶。
db.createUser({
  user : ‘admin‘,
  pwd : ‘123456‘,
  roles : [‘readWrite‘]
})
