账户权限配置

1，创建超级管理用户：

> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB
> use admin
switched to db admin
> db.createUser({
... user:"admin",
... pwd:"123",
... roles:[{role:"root",db:"admin"}]
... })
Successfully added user: {
        "user" : "admin",
        "roles" : [
                {
                        "role" : "root",
                        "db" : "admin"
                }
        ]
}
> show users
{
        "_id" : "admin.admin",
        "userId" : UUID("eb5ce3d6-7112-441e-a73b-153814f2604b"),
        "user" : "admin",
        "db" : "admin",
        "roles" : [
                {
                        "role" : "root",
                        "db" : "admin"
                }
        ],
        "mechanisms" : [
                "SCRAM-SHA-1",
                "SCRAM-SHA-256"
        ]
}
>

2，修改 MongoDb数据库配置文件：

C:Program FilesMongoDBServer4.2inmongod.cfg

3，重启Mongodb 服务

4，用超级管理员账户连接数据库：

>mongo
MongoDB shell version v4.2.8
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("6f7fa306-0dbd-4cd0-9f6d-cb8dd3ec0226") }
MongoDB server version: 4.2.8
> show dbs
> use admin
switched to db admin
> db.auth("admin","123")
1
>

5，给 hello 数据库 创建一个用户，只能访问 hello 不能访问其他数据库：

> show dbs
> db.auth("admin","123")
1
> show dbs
admin   0.000GB
config  0.000GB
hello   0.000GB
local   0.000GB
> use hello
switched to db hello
> db.createUser({
... user:"hello_admin",
... pwd:"h_123",
... roles:[{role:"dbOwner",db:"hello"}]
... })
Successfully added user: {
        "user" : "hello_admin",
        "roles" : [
                {
                        "role" : "dbOwner",
                        "db" : "hello"
                }
        ]
}
> show users
{
        "_id" : "hello.hello_admin",
        "userId" : UUID("037e9508-19c2-4940-bdd8-9517855338db"),
        "user" : "hello_admin",
        "db" : "hello",
        "roles" : [
                {
                        "role" : "dbOwner",
                        "db" : "hello"
                }
        ],
        "mechanisms" : [
                "SCRAM-SHA-1",
                "SCRAM-SHA-256"
        ]
}
>

　　

MongoDB 账户权限配置中的常用命令：

① 查看当前库下的用户  show users

② 删除用户  db.dropUser("hello_admin")

③ 修改用户密码：db.updateUser("admin" , { pwd : "password" } )

④ 密码认证：db.auth("admin" , "password")  注意是逗号

MongDb 数据库角色：

①数据库用户角色：read，readWrite

②数据库管理角色：dbAdmin  dbOwner  userAdmin

③集群管理角色：clusterAdmin  clusterManager  clusterMonitor  hostManager

④备份恢复角色：backup  restore

⑤所有数据库角色：readAnyDatabase  readWriteAnyDatabase  userAdminAnyDatabase  dbAdminAnyDatabase

⑥超级用户角色：root
