關於芒果的許可權控制說白了就是定義 Role(角色) 來控制對資料庫進行的操作(調用的方法比如查詢方法find)。

系統內置的Role分為以下幾大類：

Database User Roles 這個是針對非系統資料庫和部分系統表的角色組

Database Administration Roles 可以操作所有資料庫

Cluster Administration Roles 管理員族針對整個系統進行管理

Backup and Restoration Roles 備份還原角色組

All-Database Roles 角色裡面有一些跟超管差不多了級別了，針對所有資料庫的

Superuser Roles 超級管理員不用多說了

Internal Role 內部系統角色，比超管牛，別亂設哦

翻譯的很爛，湊合看吧,有糾正我的請留言。

MongoDB grants access to data and commands through role-based authorization and provides built-in roles that provide the different levels of access commonly needed in a database system. You can additionally createuser-defined roles.

芒果通過角色基本許可權控制授予（用戶）數據和命令的使用權，並且提供給內置角色數據系統一般需要的不同層次的許可權。另外，你也可以創建用戶定義角色。

A role grants privileges to perform sets of actions on defined resources. A given role applies to the database on which it is defined and can grant access down to a collection level of granularity.

一個角色授予許可權去執行被定義資源的操作設定。一個給定的角色適用於被定義並且可以授予集合水平力度的資料庫。

Each of MongoDB’s built-in roles defines access at the database level for all non-system collections in the role’s database and at the collection level for all system collections.

每個MongoDB的內置角色定義了訪問資料庫級的角色的資料庫中所有非系統的集合和集合級別的系統集合。

MongoDB provides the built-in database user and database administration roles on every database. MongoDB provides all other built-in roles only on the admin database.

芒果在每個資料庫上提供了內置資料庫用戶和和資料庫管理員角色。芒果僅僅在admin資料庫上提供了所有其他內置角色。

This section describes the privileges for each built-in role. You can also view the privileges for a built-in role at any time by issuing the rolesInfo command with the showPrivileges and showBuiltinRolesfields both set to true.

這節描述了各個內置角色的許可權。你可以發出rolesInfo的命令：把showPrivileges 和showBuiltinRolesfields 設為true，在任何時間查看內置角色的許可權。

All-Database Roles

所有資料庫角色

The admin database provides the following roles that apply to all databases in a mongod instance and are roughly equivalent to their single-database equivalents:

admin資料庫提供了以下角色適用於一個mongod 實例所有資料庫，這些角色基本相當於它們的單獨資料庫。

readAnyDatabase

讀任何資料庫

Provides the same read-only permissions as read, except it applies to all databases in the cluster. The role also provides the listDatabases action on the cluster as a whole.

提供和read角色一樣的只讀許可權，除了適用於集群內所有資料庫這個特性。這個角色也為整個集群提供listDatabases 操作。

讀寫任何資料庫

Provides the same read and write permissions as readWrite, except it applies to all databases in the cluster. The role also provides the listDatabases action on the cluster as a whole.

在版本2.6.4的更改：userAdminAnyDatabase 角色添加了對admin.system.users 和admin.system.roles的許可權。

The userAdminAnyDatabase role does not restrict the permissions that a user can grant. As a result,userAdminAnyDatabase users can grant themselves privileges in excess of their current privileges and even can grant themselves all privileges, even though the role does not explicitly authorize privileges beyond user administration. This role is effectively a MongoDB system superuser.

userAdminAnyDatabase 角色沒有限制用戶可以授予的許可權。結果是，userAdminAnyDatabase 的用戶們可以授予它們自己比現在更多的許可權，甚至是所有許可權，甚至不需要明確的設置超過用戶管理員許可權。這個角色實際上是芒果系統的超級用戶。

Changed in version 3.0.7: The root has validate action on system. collections. Previously, rootdoes not include any access to collections that begin with the system. prefix.

3.0.7版本修改了：root角色在系統上有 validate操作的許可權，在以前的版本中，root角色沒有包含system.首碼集合的許可權。

The root includes privileges from restore.

root角色包括了restore角色的許可權。

Internal Role

內部角色

__system

MongoDB assigns this role to user objects that represent cluster members, such as replica set members and mongos instances. The role entitles its holder to take any action against any object in the database.
