## 1.用戶授權

## (1) 在非--auth模式下啟動

/mongodb/bin/mongod --dbpath=/data/mongodb

--logpath=/mongodb/logs/mongodb.log --logappend --journal --fork

--port=27017

> use admin

switched to db admin

> db.dropDatabase();

{ "dropped" : "admin", "ok" : 1 }

> use admin

switched to db admin

## 創建一個用戶,有root權限

> db.createUser({user:"admin",pwd:"admin", roles:

[{role:"root", db:"admin"}]});

Successfully added user: {

"user" : "admin",

"roles" : [

{

"role" :

"root",

"db" :

"admin"

}

]

}

## (2) 可以看到相關集合以及關于新建用戶的內容

> show collections;

system.indexes

system.users

system.version

> db.system.users.find();

{ "_id" : "admin.admin", "user" : "admin", "db" : "admin",

"credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000,

"salt" : "2XdOg1YlUa5wwLj3Fx8WhA==", "storedKey"

:

"ENNWUOiKxfasE1Dz16qcXky44F4=", "serverKey" :

"deQB8LeyV4wkT4bfDf8gmbXiO9I=" } }, "roles" : [ { "role" : "root",

"db" : "admin" } ] }

> db.system.indexes.find();

{ "v" : 1, "key" : { "_id" : 1 }, "name" : "_id_", "ns" :

"admin.system.version" }

{ "v" : 1, "key" : { "_id" : 1 }, "name" : "_id_", "ns" :

"admin.system.users" }

{ "v" : 1, "unique" : true, "key" : { "user" : 1, "db" : 1 },

"name" : "user_1_db_1", "ns" : "admin.system.users" }

> db.system.version.find();

{ "_id" : "authSchema", "currentVersion" : 5 }

>

## (3)現在啟用--auth

/mongodb/bin/mongod --dbpath=/data/mongodb

--logpath=/mongodb/logs/mongodb.log --logappend --journal --fork

--port=27017 --auth

## 直接mongo進去,發現啥也做不了

[root@centos511 ~]# mongo

MongoDB shell version: 3.0.7

connecting to: test

> show dbs;

2016-01-13T16:01:12.396+0800 E QUERY ?Error: listDatabases failed:{

"ok" : 0,

"errmsg" : "not authorized on admin to execute

}

## (4)剛才在數據庫admin創建了一個賬戶叫admin密碼admin,

## ?先切換到admin庫進行連接(其他db則登錄失敗)：

[root@centos511 ~]# mongo

MongoDB shell version: 3.0.7

connecting to: test

> db.auth("admin","admin");

Error: 18 Authentication failed.

0

> use my_mongodb;

switched to db my_mongodb

> db.auth("admin","admin");

Error: 18 Authentication failed.

0

> use admin;

switched to db admin

> db.auth("admin","admin")

1

## db.auth("admin","admin")返回值為1，說明登錄成功！

##

db.auth("admin","admin")的記錄是不存在的，執行完后這一行在shell中不會記錄歷史。

## (5) 到admin庫直接用db.auth登錄

> use admin;

switched to db admin

> db.auth("admin","admin");

1

## 如果寫錯了庫名admin,

可以寫正確庫名admin后db.auth登錄,

## 進去后可以直接刪除,可以直接刪除

> use amin;

switched to db amin

> db.dropDatabase();

{ "ok" : 1 }

## 切換到admin庫,登錄admin用戶

> use admin;

switched to db admin

> db.auth("admin","admin");

1

> show dbs;

admin ?0.078GB

local ?0.078GB

my_mongodb ?0.078GB

test ?0.078GB

## (6) 所以現在創建另一個用戶rwuser(切換在admin數據庫創建), 有readWrite權限

>

db.createUser({user:"rwuser",pwd:"rwuser",roles:[{role:"readWrite",db:"my_mongodb"}]});

Successfully added user: {

"user" : "rwuser",

"roles" : [

{

"role" :

"readWrite",

"db" :

"my_mongodb"

}

]

}

> use my_mongodb

switched to db my_mongodb

> show tables;

system.indexes

user

## 發現無法登錄

> db.auth("rwuser","rwuser");

Error: 18 Authentication failed.

0

## 只能在admin登錄

> use admin

switched to db admin

> db.auth("rwuser","rwuser");

1

## 這時再切換到my_mongodb測試庫,可以使用

> use my_mongodb

switched to db my_mongodb

> show tables;

system.indexes

user

## (7)對于用戶, 可以增減角色:

## 增加角色:

db.grantRolesToUser("username",[{role:"",db:""}]);

db.grantRolesToUser('rwuser',[{role:"dbOwner",db:"my_mongodb"}]);

## 取消角色:

db.revokeRolesFromUser("username",[{role:"",db:""}]);

db.revokeRolesFromUser('rwuser',[{role:"readWrite",db:"my_mongodb"}]);

## 切換到admin用戶

> use admin;

switched to db admin

> db.auth("admin","admin");

1

## 授予dbOwner角色, 并取消readWrite角色

>

db.grantRolesToUser('rwuser',[{role:"dbOwner",db:"my_mongodb"}]);

>

db.revokeRolesFromUser('rwuser',[{role:"readWrite",db:"my_mongodb"}]);

## my_mongodb直接登錄失敗

> use my_mongodb;

switched to db my_mongodb

> db.auth("rwuser","rwuser");

Error: 18 Authentication failed.

0

> db

my_mongodb

## 切換到admin登錄

> use admin

switched to db admin

> db.auth("rwuser","rwuser");

1

> use my_mongodb;

switched to db my_mongodb

## dbOwner有list collections權限, 插入權限, find權限

> show collections;

system.indexes

user

>

db.user.save({"uid":3,"username":"Steven","age":27});

WriteResult({ "nInserted" : 1 })

> db.user.find({uid:3});

{ "_id" : ObjectId("56961538e8fc7d6a180d4607"), "uid" : 3,

"username" : "Steven", "age" : 27 }

(8) 在創建用戶時可以在其數據庫創建,不用每次切換到admin數據庫登錄后再切換

## 1) admin登錄

> use admin;

switched to db admin

> db.auth("admin","admin");

1

## 2) 切換到業務庫,進行創建用戶,發現可以直接在業務庫進行新用戶登錄

> use my_mongodb

switched to db my_mongodb

>

db.createUser({user:"usersteven",pwd:"usersteven",roles:[{

role:"dbOwner",db:"my_mongodb"}]});

Successfully added user: {

"user" : "usersteven",

"roles" : [

{

"role" :

"dbOwner",

"db" :

"my_mongodb"

}

]

}

> db.auth("usersteven","usersteven");

1

## 2.創建角色

## 切換到my_mongodb并且在數據庫my_mongodb中創建角色

## roles: ?創建角色"testRole"在數據庫"my_mongodb" 中

## privileges: 該角色可查看"find"數據庫"my_mongodb"的所有集合

## db.dropRole("testRole")進行刪除角色

## (1)切換admin庫admin用戶登錄

> use admin;

switched to db admin

> db.auth("admin","admin");

1

## (2)切換至my_mongodb,并創建角色,action行為配置為find

> use my_mongodb

switched to db my_mongodb

>

db.createRole({role:"testRole",privileges:[{resource:{db:"my_mongodb",collection:""},

actions:["find"]}],roles:[]});

{

"role" : "testRole",

"privileges" : [

{

"resource"

: {

"db" : "my_mongodb",

"collection" : ""

},

"actions"

: [

"find"

]

}

],

"roles" : [ ]

}

## (3) 去admin庫admin用戶登錄查看授權情況

> use admin;

switched to db admin

> show collections;

system.indexes

system.roles

system.users

system.version

> db.system.roles.find();

{ "_id" : "my_mongodb.testRole", "role" : "testRole", "db" :

"my_mongodb", "privileges" : [ { "resource" : { "db" :

"my_mongodb", "collection" : "" }, "actions" : [ "find" ] } ],

"roles" : [ ] }

## (4) 回到my_mongodb,創建用戶userwill,并授予自定義角色

> use my_mongodb

switched to db my_mongodb

>

db.createUser({user:"userwill",pwd:"userwill",roles:[{role:"testRole",

db:"my_mongodb"}]});

Successfully added user: {

"user" : "userwill",

"roles" : [

{

"role" :

"testRole",

"db" :

"my_mongodb"

}

]

}

## 退出,切庫至my_mongodb,新用戶userwill登錄

> exit

bye

[root@centos511 ~]# mongo

MongoDB shell version: 3.0.7

connecting to: test

> use my_mongodb;

switched to db my_mongodb

> db.auth("userwill","userwill");

1

## 可以find

> db.user.find({uid:3});

{ "_id" : ObjectId("56961538e8fc7d6a180d4607"), "uid" : 3,

"username" : "Steven", "age" : 27 }

## 但也只有查詢權限,

> db.user.save({"uid":4,"username":"will","age":28});

WriteResult({

"writeError" : {

"code" : 13,

"errmsg" : "not authorized on

my_mongodb to execute command { insert: "user", documents: [ {

uid: 4.0, username: "will", age: 28.0, _id:

ObjectId('56963bd65a3618cf60c7e08a') } ], ordered: true }"

}

})

##

(5)給testRole添加三個"privilege"權限:"update","insert","remove",再重新操作

## 給權限又只能切換到admin庫admin用戶登錄

> use admin;

switched to db admin

> db.auth("admin","admin");

1

>

db.grantPrivilegesToRole("testRole",[{resource:{db:"my_mongodb",collection:""},actions:["update","insert","remove"]}]);

## 退出重新登錄

> exit

[root@centos511 ~]# mongo

MongoDB shell version: 3.0.7

connecting to: test

## 切換到my_mongodb庫

> use my_mongodb

switched to db my_mongodb

## 登錄

> db.auth("userwill","userwill");

1

## 發現保存成功

> db.user.save({"uid":4,"username":"will","age":28});

WriteResult({ "nInserted" : 1 })

## uid=4記錄保存成功

> db.user.find();

{ "_id" : ObjectId("56939ea79c8c3085fbb0283d"), "uid" : 2,

"username" : "Jerry", "age" : 100 }

{ "_id" : ObjectId("56939ea79c8c3085fbb0283e"), "uid" : 1,

"username" : "Tom", "age" : 25 }

{ "_id" : ObjectId("56961538e8fc7d6a180d4607"), "uid" : 3,

"username" : "Steven", "age" : 27 }

{ "_id" : ObjectId("5697399f23598adf661315c3"), "uid" : 4,

"username" : "will", "age" : 28 }

>

## 切換至admin庫查看權限,發現不準

> use admin;

switched to db admin

> db.system.roles.find();

Error: error: { "$err" : "not authorized for query on

admin.system.roles", "code" : 13 }

## 只有登錄admin用戶才能查看權限

> db.auth("admin","admin");

1

> db.system.roles.find();

{ "_id" : "my_mongodb.testRole", "role" : "testRole", "db" :

"my_mongodb", "privileges" : [ { "resource" : { "db" :

"my_mongodb", "collection" : "" }, "actions" : [ "find", "insert",

"remove", "update" ] } ], "roles" : [ ] }

## (6) 更改角色roles, 不同于增加或減少授權, 而是完整更新。

Privileges也可以更新和替換!

> use admin

switched to db admin

> db.auth("admin","admin")

1

> use my_mongodb

switched to db my_mongodb

> db.updateRole("testRole",{ roles:[{ role: "readWrite",db:

"my_mongodb"}]},{ w:"majority" })

> db.auth("userwill","userwill");

1

> show dbs;

admin ?0.078GB

local ?0.078GB

my_mongodb ?0.078GB

test ?0.078GB
