摘要：mongodb

      MongoDB 3.0 安全權限訪問控制，在添加用戶上面3.0版本和以前的版本有很大的區別，這裏就說明下3.0的添加用戶的方法。shell

環境、測試：數據庫

      在安裝MongoDB以後，先關閉auth認證，進入查看數據庫，只有一個local庫，admin庫是不存在的：json

root@zhoujinyi:/usr/local/mongo4# mongo --port=27020
MongoDB shell version: 3.0.4
connecting to: 127.0.0.1:27020/test
2015-06-29T09:31:08.673-0400 I CONTROL  [initandlisten] 
> show dbs;
local  0.078GB

如今須要建立一個賬號，該帳號須要有grant權限，即：帳號管理的受權權限。注意一點，賬號是跟着庫走的，因此在指定庫裏受權，必須也在指定庫裏驗證(auth)。ubuntu

上面加粗的就是執行的命令：數組

user：用戶名安全

pwd：密碼函數

roles：指定用戶的角色，能夠用一個空數組給新用戶設定空角色；在roles字段,能夠指定內置角色和用戶定義的角色。role裏的角色能夠選：測試

複製代碼 
  Built-In Roles（內置角色）：
    1. 數據庫用戶角色：read、readWrite;
    2. 數據庫管理角色：dbAdmin、dbOwner、userAdmin；
    3. 集羣管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；
    4. 備份恢復角色：backup、restore；
    5. 全部數據庫角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase
    6. 超級用戶角色：root  
    // 這裏還有幾個角色間接或直接提供了系統超級用戶的訪問（dbOwner 、userAdmin、userAdminAnyDatabase）
    7. 內部角色：__system
複製代碼

具體角色： ui

複製代碼 
Read：容許用戶讀取指定數據庫
readWrite：容許用戶讀寫指定數據庫
dbAdmin：容許用戶在指定數據庫中執行管理函數，如索引建立、刪除，查看統計或訪問system.profile
userAdmin：容許用戶向system.users集合寫入，能夠找指定數據庫裏建立、刪除和管理用戶
clusterAdmin：只在admin數據庫中可用，賦予用戶全部分片和複製集相關函數的管理權限。
readAnyDatabase：只在admin數據庫中可用，賦予用戶全部數據庫的讀權限
readWriteAnyDatabase：只在admin數據庫中可用，賦予用戶全部數據庫的讀寫權限
userAdminAnyDatabase：只在admin數據庫中可用，賦予用戶全部數據庫的userAdmin權限
dbAdminAnyDatabase：只在admin數據庫中可用，賦予用戶全部數據庫的dbAdmin權限。
root：只在admin數據庫中可用。超級帳號，超級權限
複製代碼

剛創建了 userAdminAnyDatabase 角色，用來管理用戶，能夠經過這個角色來建立、刪除用戶。驗證：須要開啓auth參數。

有沒有一個超級權限？不只能夠受權，並且也能夠對集合進行任意操做？答案是確定的，只是不建議使用。那就是role角色設置成root。

由於賬號都是在當前須要受權的數據庫下受權的，那要是不在當前數據庫下會怎麼樣？

上面更加進一步說明數據庫賬號是跟着數據庫來走的，哪裏建立哪裏認證。

建立了這麼多賬號，怎麼查看全部賬號？
