MongoDB3.0.x版本用户授权配置(单机环境)
MongoDB数据库默认情况下是没有做权限控制的,只要能够连接所开放的端口就能进行访问,而且拥有root级别的权限;对于生产环境而言是极不安全的,所以需要建立用户,进行授权控制。
-
单机环境下的用户授权模块配置:
MongoDB的社区版本中有两个模块可以控制用户的访问:
-
首先验证下非配置认证模块的访问:
[root@fo169 bin]# ./mongo MongoDB shell version: 3.0.7 connecting to: test Server has startup warnings: 2015-10-29T15:12:14.257+0800 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended. 2015-10-29T15:12:14.257+0800 I CONTROL [initandlisten] > show dbs local 0.000GB
在没有配置的情况下,登录到数据库后,可以做任何操作。
-
配置认证模块及重启服务:
编写了一个启动配置文件:mongodb.conf(文件中标红部分就为auth的授权模块)
[root@fo169 bin]# cat mongodb.conf
systemLog:
destination: file
path: "/data/auth/log/mongod.log"
logAppend: true
storage:
journal:
enabled: true
dbPath: "/data/auth/db"
directoryPerDB: true
engine: wiredTiger
wiredTiger:
engineConfig:
cacheSizeGB: 4
directoryForIndexes: true
journalCompressor: zlib
collectionConfig:
blockCompressor: zlib
indexConfig:
prefixCompression: true
net:
port: 27017
processManagement:
fork: true
security:
authorization: enabled

创建授权用户(超级管理员):
MongoDB在V3.0版本之后内置了root 角色,也就是结合了readWriteAnyDatabase、dbAdminAnyDatabase、userAdminAnyDatabase、clusterAdmin4个角色权限,类似于ORACLE的sysdba角色,但是MongoDB的超级管理员用户名称是可以随便定义的:
[root@fo169 bin]# ./mongo MongoDB shell version: 3.0.7 connecting to: test Server has startup warnings: 2015-10-30T16:24:36.127+0800 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended. 2015-10-30T16:24:36.127+0800 I CONTROL [initandlisten] > use admin switched to db admin > db.createUser( ... { ... user: "ljaiadmin", ... pwd: "123456", ... roles: [ { role: "root", db: "admin" } ] ... } ... ) Successfully added user: { "user" : "ljaiadmin", "roles" : [ { "role" : "root", "db" : "admin" } ] }
这样就创建好一个ljaiadmin的超级管理员用户,创建全局用户或者超级用户,需要在MongoDB的admin数据库中创建(在其他库也可以创建,但是没有该角色功能),重启完mongod进程后,接下来做一下权限的验证:
[root@fo169 bin]# ./mongo MongoDB shell version: 3.0.7 connecting to: test > show dbs (注:此时查看已提示没有授权执行listDatabases命令了) 2015-10-30T16:41:31.131+0800 E QUERY Error: listDatabases failed:{ "ok" : 0, "errmsg" : "not authorized on admin to execute command { listDatabases: 1.0 }", "code" : 13 } at Error (<anonymous>) at Mongo.getDBs (src/mongo/shell/mongo.js:47:15) at shellHelper.show (src/mongo/shell/utils.js:630:33) at shellHelper (src/mongo/shell/utils.js:524:36) at (shellhelp2):1:1 at src/mongo/shell/mongo.js:47 > use admin switched to db admin > db.auth('ljaiadmin','123456') (注:切换到admin用户进行授权验证) 1 > show dbs (注:验证完成后,就可以读写等操作) admin 0.000GB local 0.000GB test100 0.000GB test2 0.000GB > use test2 switched to db test2 > show tables test test2 > db.test2.find() { "_id" : ObjectId("5632cf116207909a76446af7"), "name" : "1" } > db.test2.drop() true > db.dropDatabase() { "dropped" : "test2", "ok" : 1 } > show dbs admin 0.000GB local 0.000GB test100 0.000GB > use test100 switched to db test100 > db.test111.insert({"test":"test"}) WriteResult({ "nInserted" : 1 }) > db.test111.find() { "_id" : ObjectId("56332db373f771b3d95638bb"), "test" : "test" } > use admin switched to db admin > show users { "_id" : "admin.ljaiadmin", "user" : "ljaiadmin", "db" : "admin", "roles" : [ { "role" : "root", "db" : "admin" } ] } >

创建普通用户
用可以对test123数据库读写的rwtest123用户为例:
> use test123 switched to db test123 > db.createUser( ... { ... user: "rwtest123", ... pwd: "123456", ... roles: [ { role: "readWrite", db: "test123" } ] ... } ... ) Successfully added user: { "user" : "rwtest123", "roles" : [ { "role" : "readWrite", "db" : "test123" } ] }
#所建的rwtest123用户可以在test123数据库中进行增删改查操作,但是其他操作就不行了 >db.auth('rwtest123','123456') switched to db test123 > db.test123.insert({"test":"test"}) WriteResult({ "nInserted" : 1 }) > db.test123.find() { "_id" : ObjectId("563332ebc8a59ae4fe96bbf5"), "test" : "test" } > db.test123.drop() true > use test100 switched to db test100 > db.test100.find() Error: error: { "$err" : "not authorized for query on test100.test100", "code" : 13 } >

配置参考:
MongoDB数据库的用户权限控制权限还是比较多的,有系统自带的,已经定义好的角色,也可以自己定义角色权限,需要根据业务需要进行权限分配:
自带角色的说明(一般内置的角色基本上就可以满足生产环境需求了):

用户自行定义角色的说明:
