mongodb基础之用户权限管理实例教程

人气:0

前言

本文主要介绍了mongodb用户权限管理的相关内容,关于接着上次实践的部分,下面话不多说了,来一起看看详细的介绍吧

启动mongodb并连接

./bin/mongod -f conf/mongod.conf
./bin/mongo 127.0.0.1:12345

查看默认的数据库情况

> show dbs
admin 0.000GB
local 0.000GB

> use admin
switched to db admin
> show tables
system.version

可以看到,目前数据库里除了一些基本信息,什么都没有

在创建设置用户权限之前,先了解一下文档知识

创建用户

# demo
db.createUser(
 {
 user: "reportsUser",
 pwd: "12345678",
 roles: [
  { role: "read", db: "reporting" },
  { role: "read", db: "products" },
  { role: "read", db: "sales" },
  { role: "readWrite", db: "accounts" }
 ]
 }
)

数据库内建角色

数据库用户角色

数据库管理角色

集群管理角色

备份恢复角色

所有数据库角色

超级用户角色

内部角色

有了创建语法,和参数说明,接下来开始实践.

注意,还有一点,账号是跟着数据库绑定的,在那个库里授权,就在那个库里验证(auth)
否则会失败

创建 账号管理授权权限 的账号

> db.createUser(
... {
... user: 'admin',
... pwd: '123456',
... roles: [{role: 'userAdminAnyDatabase', db: 'admin'}]
... }
... )
Successfully added user: {
  "user" : "admin",
  "roles" : [
    {
      "role" : "userAdminAnyDatabase",
      "db" : "admin"
    }
  ]
}

然后退出数据库

> use admin
switched to db admin
> db.shutdownServer()

重新启动mongodb,记得在配置文件mongod.conf里加上 auth = true

./bin/mongod -f conf/mongod.conf
./bin/mongo 127.0.0.1:12345
> show dbs # 没有验证,没有权限,会出错
"errmsg" : "not authorized on admin to execute command
> use admin
> db.auth('admin', '123456')
1
# 返回 1 表示授权成功,0表示失败
> show dbs #已经授权,可以查看了

创建 读、读写权限的账户

> use book
switched to db book
> db.createUser(
... {
... user: 'zhangsan',
... pwd: 'zhangsan',
... roles: [{role: 'read', db: 'book'}]
... }
... )
Successfully added user: {
  "user" : "zhangsan",
  "roles" : [
    {
      "role" : "read",
      "db" : "book"
    }
  ]
}
> db.createUser(
... {
... user: 'lisi',
... pwd: 'lisi',
... roles: [{role: 'readWrite', db: 'book'}]
... }
... )
Successfully added user: {
  "user" : "lisi",
  "roles" : [
    {
      "role" : "readWrite",
      "db" : "book"
    }
  ]
}
> show users
{
  "_id" : "book.lisi",
  "user" : "lisi",
  "db" : "book",
  "roles" : [
    {
      "role" : "readWrite",
      "db" : "book"
    }
  ]
}
{
  "_id" : "book.zhangsan",
  "user" : "zhangsan",
  "db" : "book",
  "roles" : [
    {
      "role" : "read",
      "db" : "book"
    }
  ]
}

然后验证用户权限是否正确

> db.book.insert({book: '小人书'}) # 没验证,会出错
WriteResult({
  "writeError" : {
    "code" : 13,
    "errmsg" : "not authorized on book to execute command { insert: \"book\", docum
ents: [ { _id: ObjectId('5959b56edcc047dfe5c9b336'), book: \"小人书\" } ], ordered: true }"
  }
})
> db.auth('lisi', 'lisi')
1
> db.book.insert({book: '小人书'})
WriteResult({ "nInserted" : 1 })
> db.auth('zhangsan', 'zhangsan') # 用户切到 zhangsan
1
> db.book.find() # 可以查看
{ "_id" : ObjectId("5959b59fdcc047dfe5c9b337"), "book" : "小人书" }
> db.book.insert({book: '择天记'}) # 没有write权限,会失败
WriteResult({
  "writeError" : {
    "code" : 13,
    "errmsg" : "not authorized on book to execute command { insert: \"book\", docum
ents: [ { _id: ObjectId('5959b650dcc047dfe5c9b338'), book: \"择天记\" } ], ordered: true }"
  }
})

创建 root 超级权限账号

这个超级权限包括 授权 和 操控数据库集合数据,比较简单,只需要把role设置成 root

> use admin
switched to db admin
> db.auth('admin', '123456')
1
> db.createUser(
... {
... user: 'dongsheng',
... pwd: '123456',
... roles: [{role: 'root', db: 'admin'}]
... }
... )
Successfully added user: {
  "user" : "dongsheng",
  "roles" : [
    {
      "role" : "root",
      "db" : "admin"
    }
  ]
}
> db.auth('dongsheng', '123456')
1
> use book
switched to db book
> db.book.insert({book: '笑傲江湖'})
WriteResult({ "nInserted" : 1 })
> db.book.find()
{ "_id" : ObjectId("5959b59fdcc047dfe5c9b337"), "book" : "小人书" }
{ "_id" : ObjectId("5959b7abdcc047dfe5c9b339"), "book" : "笑傲江湖" }
