环境
MongoDB shell version: 3.2.6
Win 7
设置方法
用户权限设置
1、进入mongodb的shell ：mongo
2、切换数据库：use admin
从3.0 版本起，默认只有local库，没有admin库，需要我们自己来创建。
3、添加用户，指定用户的角色和数据库：
db.createUser(
{ user: "admin",
customData：{description:"superuser"},
pwd: "admin",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)
user字段，为新用户的名字；
pwd字段，用户的密码；
cusomData字段，为任意内容，例如可以为用户全名介绍；
roles字段，指定用户的角色，可以用一个空数组给新用户设定空角色。在roles字段,可以指定内置角色和用户定义的角色。
4、查看创建的用户 ：show users或db.system.users.find()
5、启用用户权限：
修改配置文件，增加配置：
security:
authorization: enabled
重新启动mongodb
net stop mongodb;
net start mongodb;
6、用户验证使用：
启用用户验证后，再次登录mongo shell ，执行show dbs等命令会提示“没有权限”。此时，需要用户验证登录。
db.auth("admin","admin")
其他
内建的角色
数据库用户角色：read、readWrite;
数据库管理角色：dbAdmin、dbOwner、userAdmin；
集群管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；
备份恢复角色：backup、restore；
所有数据库角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase
超级用户角色：root
// 这里还有几个角色间接或直接提供了系统超级用户的访问（dbOwner 、userAdmin、userAdminAnyDatabase）
内部角色：__system
