现在需要创建一个帐号，该账号需要有grant权限，即：账号管理的授权权限。注意一点，帐号是跟着库走的，所以在指定库里授权，必须也在指定库里验证(auth)

1.在admin库中，添加用户并授权 use admin;
db.createUser(
{
user: "boot_admin",
pwd: "boot_admin",
roles:
[
{
role: "readWrite",
db: "admin"
}
]
}
);
2.在admin库中验证 use admin;
db.auth('boot_admin', 'boot_admin')
|
说明：
user：用户名
pwd：密码
roles：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。role里的角色可以选：

Built-In Roles（内置角色）：
1. 数据库用户角色：read、readWrite;
2. 数据库管理角色：dbAdmin、dbOwner、userAdmin；
3. 集群管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；
4. 备份恢复角色：backup、restore；
5. 所有数据库角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase
6. 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）
7. 内部角色：__system

Read：允许用户读取指定数据库
readWrite：允许用户读写指定数据库dbAdmin：允许用户在指定数据库中执行管理函数，如索引创建、删除，查看统计或访问system.profileuserAdmin：允许用户向system.users集合写入，可以找指定数据库里创建、删除和管理用户clusterAdmin：只在admin数据库中可用，赋予用户所有分片和复制集相关函数的管理权限。readAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的读权限readWriteAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的读写权限userAdminAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的userAdmin权限dbAdminAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的dbAdmin权限。root：只在admin数据库中可用。超级账号，超级权限 |

刚建立了 userAdminAnyDatabase 角色，用来管理用户，可以通过这个角色来创建、删除用户。验证：需要开启auth参数。

有没有一个超级权限？不仅可以授权，而且也可以对集合进行任意操作？答案是肯定的，只是不建议使用。那就是role角色设置成root。

因为帐号都是在当前需要授权的数据库下授权的，那要是不在当前数据库下会怎么样？

上面更加进一步说明数据库帐号是跟着数据库来走的，哪里创建哪里认证。
创建了这么多帐号，怎么查看所有帐号？
