mongoDB 3.0 安全权限访问控制

MongoDB3.0权限，啥都不说了，谷歌百度出来的全是错的。先安装好盲沟，简单的没法说。

首先，不使用 —auth 参数，启动 mongoDB：

mongodb-linux-i686-3.0.0/bin/mongod -f mongodb-linux-i686-3.0.0/mongodb.conf 

此时你 show dbs 会看到只有一个local数据库，那个所谓的admin是不存在的。

mongoDB 没有炒鸡无敌用户root，只有能管理用户的用户 userAdminAnyDatabase。

打开 mongo shell：

mongodb-linux-i686-3.0.0/bin/mongo 

添加管理用户：

use admin db.createUser(  {  user: "buru",  pwd: "12345678",  roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]  } ) 

roles 中的 db 参数是必须的，不然会报错：Error: couldn’t add user: Missing expected field “db”。另外，有很多文章记录的是使用 db.addUser(…) 方法，这个方法是旧版的，3.0中已经不存在，详见：http://docs.mongodb.org/manual/reference/method/js-user-management。

切换到admin下，查看刚才创建的用户：

show users 或 db.system.users.find() 

{ "_id" : "admin.buru", "user" : "buru", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "gwVwuA/dXvxgSHavEnlyvA==", "storedKey" : "l2QEVTEujpkCuqDEKqfIWbSv4ms=", "serverKey" : "M1ofNKXg2sNCsFrBJbX4pXbSgvg=" } }, "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] } 

怎么关闭 mongoDB？千万不要 kill -9 pid，可以 kill -2 pid 或 db.shutdownServer()

下面使用 —auth 参 数，重新启动 mongoDB：

mongodb-linux-i686-3.0.0/bin/mongod --auth -f mongodb-linux-i686-3.0.0/mongodb.conf 

再次打开 mongo shell：

mongodb-linux-i686-3.0.0/bin/mongo use admin db.auth("buru","12345678") #认证，返回1表示成功 或 mongodb-linux-i686-3.0.0/bin/mongo -u buru -p 12345678 --authenticationDatabase admin 

此时

show collections 

报错

2015-03-17T10:15:56.011+0800 E QUERY Error: listCollections failed: {  "ok" : 0,  "errmsg" : "not authorized on admin to execute command { listCollections: 1.0 }",  "code" : 13 }  at Error (<anonymous>)  at DB._getCollectionInfosCommand (src/mongo/shell/db.js:643:15)  at DB.getCollectionInfos (src/mongo/shell/db.js:655:20)  at DB.getCollectionNames (src/mongo/shell/db.js:666:17)  at shellHelper.show (src/mongo/shell/utils.js:625:12)  at shellHelper (src/mongo/shell/utils.js:524:36)  at (shellhelp2):1:1 at src/mongo/shell/db.js:643 

因为，用户buru只有用户管理的权限。

下面创建用户，用户都跟着库走，创建的用户都是

use tianhe db.createUser(  {  user: "bao",  pwd: "12345678",  roles: [  { role: "readWrite", db: "tianhe" },  { role: "read", db: "tianhe2" }  ]  } ) 

查看刚刚创建的用户。

show users  {  "_id" : "tianhe.bao",  "user" : "bao",  "db" : "tianhe",  "roles" : [  {  "role" : "readWrite",  "db" : "tianhe"  },  {  "role" : "read",  "db" : "tianhe2"  }  ] } 

查看整个mongoDB全部的用户：

use admin db.system.users.find()  { "_id" : "admin.buru", "user" : "buru", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "gwVwuA/dXvxgSHavEnlyvA==", "storedKey" : "l2QEVTEujpkCuqDEKqfIWbSv4ms=", "serverKey" : "M1ofNKXg2sNCsFrBJbX4pXbSgvg=" } }, "roles" : [ { "role" : "userAdminAnyDatabase", "db" : "admin" } ] } { "_id" : "tianhe.bao", "user" : "bao", "db" : "tianhe", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "//xy1V1fbqEHC1gzQqZHGQ==", "storedKey" : "ZS/o54zzl/FdcXLQJ98KdAVTfF0=", "serverKey" : "iIpNYz2Gk8KhyK3zgz6muBt0PI4=" } }, "roles" : [ { "role" : "readWrite", "db" : "tianhe" }, { "role" : "read", "db" : "tianhe2" } ] } 

创建完毕，验证一下：

use buru show collections  2015-03-17T10:30:06.461+0800 E QUERY Error: listCollections failed: {  "ok" : 0,  "errmsg" : "not authorized on buru to execute command { listCollections: 1.0 }",  "code" : 13 }  at Error (<anonymous>)  at DB._getCollectionInfosCommand (src/mongo/shell/db.js:643:15)  at DB.getCollectionInfos (src/mongo/shell/db.js:655:20)  at DB.getCollectionNames (src/mongo/shell/db.js:666:17)  at shellHelper.show (src/mongo/shell/utils.js:625:12)  at shellHelper (src/mongo/shell/utils.js:524:36)  at (shellhelp2):1:1 at src/mongo/shell/db.js:643 ` 

显然没权限，先auth：

db.auth("bao","12345678") 1 show collections news system.indexes wahaha
