摘要：
MongoDB 3.0 安全权限访问控制，在添加用户上面3.0版本和之前的版本有很大的区别，这里就说明下3.0的添加用户的方法。
环境、测试：
在安装MongoDB之后，先关闭auth认证，进入查看数据库，只有一个local库，admin库是不存在的：
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
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)。
> use admin
switched to db admin
> db.createUser(
... {
... user: "dba",
... pwd: "dba",
... roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
... }
... )
Successfully added user: {
"user" : "dba",
"roles" : [
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
}
]
}
上面加粗的就是执行的命令：
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
具体角色：
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.profile userAdmin：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。

上面创建了2个帐号，现在验证下：验证前提需要一个集合

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。
> db.auth(‘dba‘,‘dba‘)
1
> db.createUser(
... {
... user: "zhoujinyi",
... pwd: "zhoujinyi",
... roles: [
... { role: "root", db: "admin" } #超级root帐号
... ]
... }
... )
Successfully added user: {

}
{

"roles" : [

WriteResult({ "nInserted" : 1 })
> db.abc.find()
{ "_id" : ObjectId("5591539bb78649ebd8316857"), "a" : 1, "b" : 2 }

> db.abc.remove({})
WriteResult({ "nRemoved" : 2 })
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？
> db
admin
> db.createUser(
... {
... user: "dxy",
... pwd: "dxy",
... roles: [
... { role: "readWrite", db: "test" }, #在当前库下创建其他库的帐号，在admin库下创建test、abc库的帐号
... { role: "readWrite", db: "abc" }
... ]
... }
... )
Successfully added user: {
"user" : "dxy",

{
"role" : "readWrite",

},
{
"role" : "readWrite",

}
]
}
>

"user" : "dxy",
"db" : "admin",
"roles" : [
{
"role" : "readWrite",
"db" : "test"
},
{
"role" : "readWrite",
"db" : "abc"
}
]
}
> use test
switched to db test
> db.auth(‘dxy‘,‘dxy‘) #在admin下创建的帐号，不能直接在其他库验证，
Error: 18 Authentication failed.
0
> use admin

> db.auth(‘dxy‘,‘dxy‘)

> use test

> db.abc.insert({"a":1111,"b":2222})
WriteResult({ "nInserted" : 1 })
> use abc
switched to db abc
> db.abc.insert({"a":1111,"b":2222})
WriteResult({ "nInserted" : 1 })
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？
