mongodb安全

1.流程:

　　(1)创建超级管理员

　　(2)修改配置文件，验证身份登录

　　(3)重启服务

　　(4)使用超级管理员登录

　　(5)创建普通用户

　　(6)使用普通用户登录对应的数据库

mongodb数据库角色:

1创建用户:(只要指明角色和授予的数据库)

创建用户:(注意切换到admin数据库:)

> use admin
switched to db admin
> db.createUser({"user":"root",pwd:"",roles:[{role:"root",db:"admin"}]})
Successfully added user: {
        "user" : "root",
        "roles" : [
                {
                        "role" : "root",
                        "db" : "admin"
                }
        ]
}

 2.修改配置文件，启动验证身份:

• linux下面修改/etc/mongod.conf (注意后面有空格)

重启服务即可

• windows下面:  在启动mongod的时候后面携带--auth 参数，其中参数有很多，在最后会附上启动参数。

mongod --auth

　　如果需要制定数据路径:

mongod --auth --dbpath c:\data\db

　　因此可以将上面命令写入一bat脚本。(前提是将mongod的目录配置到环境变量path)

例如我的一个bat脚本:(我的安装目录是E:\mongodb\mongodb-win32-x86_64-enterprise-windows-64-3.6.3\bin)

e:
cd E:\mongodb\mongodb-win32-x86_64-enterprise-windows--3.6.\bin
mongod.exe --auth --dbpath c:\data\db
pause

 3.登录数据库:(需要制定数据库和密码)

直接登录:

mongo -u root -p  --authenticationDatabase admin

　　这是以管理员身份登录，登录之后可以对任何数据库进行操作

因此将上面命令也可以写成一个脚本:

e:
cd E:\mongodb\mongodb-win32-x86_64-enterprise-windows--3.6.\bin
mongod.exe --auth --dbpath c:\data\db
pause

4.实际开发中是超级管理员创建一普通账户并给其分配对应的数据库，因此此用户只能操作其对应的数据库

• 创建普通用户(对mydb数据库具有读写权限，账号密码都是user)

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

• 重启服务之后测试:

C:\Users\liqiang>mongo -u user -p user --authenticationDatabase admin　　#普通用户登录admin数据库报错
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.
--26T22::07.191+ E QUERY    [thread1] Error: Authentication failed.

C:\Users\liqiang>mongo -u user -p user --authenticationDatabase mydb　　#普通用户登录分配给他的mydb数据库正常
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.

MongoDB Enterprise > db

MongoDB Enterprise > use mydb　　#访问admin数据库报错
switched to db mydb
MongoDB Enterprise > show tables   #访问mydb正常
