? ? ? MongoDB 3.0 安全權(quán)限訪問控制，在添加用戶上面3.0版本和之前的版本有很大的區(qū)別，這里就說明下3.0的添加用戶的方法。

環(huán)境、測試：

? ? ? 在安裝MongoDB之后，先關(guān)閉auth認(rèn)證，進(jìn)入查看數(shù)據(jù)庫，只有一個(gè)local庫，admin庫是不存在的：

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

現(xiàn)在需要?jiǎng)?chuàng)建一個(gè)帳號，該賬號需要有g(shù)rant權(quán)限，即：賬號管理的授權(quán)權(quán)限。注意一點(diǎn)，帳號是跟著庫走的，所以在指定庫里授權(quán)，必須也在指定庫里驗(yàn)證(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" } ] }

上面加粗的就是執(zhí)行的命令：

user：用戶名

pwd：密碼

roles：指定用戶的角色，可以用一個(gè)空數(shù)組給新用戶設(shè)定空角色；在roles字段,可以指定內(nèi)置角色和用戶定義的角色。role里的角色可以選：

Built-In Roles（內(nèi)置角色）：1. 數(shù)據(jù)庫用戶角色：read、readWrite;2. 數(shù)據(jù)庫管理角色：dbAdmin、dbOwner、userAdmin； 3. 集群管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager； 4. 備份恢復(fù)角色：backup、restore； 5. 所有數(shù)據(jù)庫角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase 6. 超級用戶角色：root // 這里還有幾個(gè)角色間接或直接提供了系統(tǒng)超級用戶的訪問（dbOwner 、userAdmin、userAdminAnyDatabase） 7. 內(nèi)部角色：__system

具體角色：?

Read：允許用戶讀取指定數(shù)據(jù)庫 readWrite：允許用戶讀寫指定數(shù)據(jù)庫 dbAdmin：允許用戶在指定數(shù)據(jù)庫中執(zhí)行管理函數(shù)，如索引創(chuàng)建、刪除，查看統(tǒng)計(jì)或訪問system.profile userAdmin：允許用戶向system.users集合寫入，可以找指定數(shù)據(jù)庫里創(chuàng)建、刪除和管理用戶 clusterAdmin：只在admin數(shù)據(jù)庫中可用，賦予用戶所有分片和復(fù)制集相關(guān)函數(shù)的管理權(quán)限。 readAnyDatabase：只在admin數(shù)據(jù)庫中可用，賦予用戶所有數(shù)據(jù)庫的讀權(quán)限 readWriteAnyDatabase：只在admin數(shù)據(jù)庫中可用，賦予用戶所有數(shù)據(jù)庫的讀寫權(quán)限 userAdminAnyDatabase：只在admin數(shù)據(jù)庫中可用，賦予用戶所有數(shù)據(jù)庫的userAdmin權(quán)限 dbAdminAnyDatabase：只在admin數(shù)據(jù)庫中可用，賦予用戶所有數(shù)據(jù)庫的dbAdmin權(quán)限。 root：只在admin數(shù)據(jù)庫中可用。超級賬號，超級權(quán)限

剛建立了?userAdminAnyDatabase?角色，用來管理用戶，可以通過這個(gè)角色來創(chuàng)建、刪除用戶。驗(yàn)證：需要開啟auth參數(shù)。

上面創(chuàng)建了2個(gè)帳號，現(xiàn)在驗(yàn)證下：驗(yàn)證前提需要一個(gè)集合

> db.abc.insert({"a":1,"b":2}) #插入失敗，沒有權(quán)限，userAdminAnyDatabase 權(quán)限只是針對用戶管理的，對其他是沒有權(quán)限的。 WriteResult({"writeError" : {"code" : 13, "errmsg" : "not authorized on test to execute command { insert: \"abc\", documents: [ { _id: ObjectId('55915185d629831d887ce2cb'), a: 1.0, b: 2.0 } ], ordered: true }" } }) > bye root@zhoujinyi:/usr/local/mongo4# mongo --port=27020 MongoDB shell version: 3.0.4 connecting to: 127.0.0.1:27020/test > use test switched to db test > db.auth('zjy','zjy') #用創(chuàng)建的readWrite帳號進(jìn)行寫入 1 > db.abc.insert({"a":1,"b":2}) WriteResult({ "nInserted" : 1 }) > db.abc.insert({"a":11,"b":22}) WriteResult({ "nInserted" : 1 }) > db.abc.insert({"a":111,"b":222}) WriteResult({ "nInserted" : 1 }) > db.abc.find() { "_id" : ObjectId("559151a1b78649ebd8316853"), "a" : 1, "b" : 2 } { "_id" : ObjectId("559151cab78649ebd8316854"), "a" : 11, "b" : 22 } { "_id" : ObjectId("559151ceb78649ebd8316855"), "a" : 111, "b" : 222 } > db.auth('zjyr','zjyr') #切換到只有read權(quán)限的帳號 1 > db.abc.insert({"a":1111,"b":2222}) #不能寫入 WriteResult({ "writeError" : { "code" : 13, "errmsg" : "not authorized on test to execute command { insert: \"abc\", documents: [ { _id: ObjectId('559151ebb78649ebd8316856'), a: 1111.0, b: 2222.0 } ], ordered: true }" } }) > db.abc.find() #可以查看 { "_id" : ObjectId("559151a1b78649ebd8316853"), "a" : 1, "b" : 2 } { "_id" : ObjectId("559151cab78649ebd8316854"), "a" : 11, "b" : 22 } { "_id" : ObjectId("559151ceb78649ebd8316855"), "a" : 111, "b" : 222 }

有沒有一個(gè)超級權(quán)限？不僅可以授權(quán)，而且也可以對集合進(jìn)行任意操作？答案是肯定的，只是不建議使用。那就是role角色設(shè)置成root。

> db.auth('dba','dba') 1 > db.createUser( ... { ... user: "zhoujinyi", ... pwd: "zhoujinyi", ... roles: [ ... { role: "root", db: "admin" } #超級root帳號 ... ] ... } ... ) Successfully added user: { "user" : "zhoujinyi", "roles" : [ { "role" : "root", "db" : "admin" } ] } > > show users; #查看當(dāng)前庫下的用戶 { "_id" : "admin.dba", "user" : "dba", "db" : "admin", "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] } { "_id" : "admin.zhoujinyi", "user" : "zhoujinyi", "db" : "admin", "roles" : [ { "role" : "root", "db" : "admin" } ] } > use admin switched to db admin > db.auth('zhoujinyi','zhoujinyi') 1 > use test switched to db test > db.abc.insert({"a":1,"b":2}) WriteResult({ "nInserted" : 1 }) > db.abc.insert({"a":1111,"b":2222}) #權(quán)限都有 WriteResult({ "nInserted" : 1 }) > db.abc.find() { "_id" : ObjectId("5591539bb78649ebd8316857"), "a" : 1, "b" : 2 } { "_id" : ObjectId("559153a0b78649ebd8316858"), "a" : 1111, "b" : 2222 } > db.abc.remove({}) WriteResult({ "nRemoved" : 2 })

因?yàn)閹ぬ柖际窃诋?dāng)前需要授權(quán)的數(shù)據(jù)庫下授權(quán)的，那要是不在當(dāng)前數(shù)據(jù)庫下會怎么樣？

> db admin > db.createUser( ... { ... user: "dxy", ... pwd: "dxy", ... roles: [ ... { role: "readWrite", db: "test" }, #在當(dāng)前庫下創(chuàng)建其他庫的帳號，在admin庫下創(chuàng)建test、abc庫的帳號 ... { role: "readWrite", db: "abc" } ... ] ... } ... ) Successfully added user: { "user" : "dxy", "roles" : [ { "role" : "readWrite", "db" : "test" }, { "role" : "readWrite", "db" : "abc" } ] } > > show users; { "_id" : "admin.dba", "user" : "dba", "db" : "admin", "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] } { "_id" : "admin.zhoujinyi", "user" : "zhoujinyi", "db" : "admin", "roles" : [ { "role" : "root", "db" : "admin" } ] } { "_id" : "admin.dxy", "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下創(chuàng)建的帳號，不能直接在其他庫驗(yàn)證， Error: 18 Authentication failed. 0 > use admin switched to db admin #只能在帳號創(chuàng)建庫下認(rèn)證，再去其他庫進(jìn)行操作。 > db.auth('dxy','dxy') 1 > use test switched to db 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 })

上面更加進(jìn)一步說明數(shù)據(jù)庫帳號是跟著數(shù)據(jù)庫來走的，哪里創(chuàng)建哪里認(rèn)證。

創(chuàng)建了這么多帳號，怎么查看所有帳號？

> use admin switched to db admin > db.auth('dba','dba') 1 > db.system.users.find().pretty() { "_id" : "admin.dba", "user" : "dba", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "KfDUzCOIUo7WVjFr64ZOcQ==", "storedKey" : "t4sPsKG2dXnZztVYj5EgdUzT9sc=", "serverKey" : "2vCGiq9NIc1zKqeEL6VvO4rP26A=" } }, "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] } { "_id" : "test.zjyr", "user" : "zjyr", "db" : "test", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "h1gOW3J7wzJuTqgmmQgJKQ==", "storedKey" : "7lkoANdxM2py0qiDBzFaZYPp1cM=", "serverKey" : "Qyu6IRNyaKLUvqJ2CAa/tQYY36c=" } }, "roles" : [ { "role" : "read", "db" : "test" } ] } { "_id" : "test.zjy", "user" : "zjy", "db" : "test", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "afwaKuTYPWwbDBduQ4Hm7g==", "storedKey" : "ebb2LYLn4hiOVlZqgrAKBdStfn8=", "serverKey" : "LG2qWwuuV+FNMmr9lWs+Rb3DIhQ=" } }, "roles" : [ { "role" : "readWrite", "db" : "test" } ] } { "_id" : "admin.zhoujinyi", "user" : "zhoujinyi", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "pE2cSOYtBOYevk8tqrwbSQ==", "storedKey" : "TwMxdnlB5Eiaqg4tNh9ByNuUp9A=", "serverKey" : "Mofr9ohVlFfR6/md4LMRkOhXouc=" } }, "roles" : [ { "role" : "root", "db" : "admin" } ] } { "_id" : "admin.dxy", "user" : "dxy", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "XD6smcWX4tdg/ZJPoLxxRg==", "storedKey" : "F4uiayykHDp/r9krAKZjdr+gqjM=", "serverKey" : "Kf51IU9J3RIrB8CFn5Z5hEKMSkw=" } }, "roles" : [ { "role" : "readWrite", "db" : "test" }, { "role" : "readWrite", "db" : "abc" } ] } > db.system.users.find().count() 5
