mongo开启验证

mongodb刚安装完,

创建超级用户

$mongo        #进入mongo控制台
MongoDB shell version v3.4.10
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.10
>

> use admin   #进入admin库
switched to db admin  
> db          #查看当前数据库
admin 

> db.createUser({user:"master",pwd:"123456",roles:[{"role":"userAdminAnyDatabase","db":"admin"}]})           #创建超级用户
Successfully added user: {  
        "user" : "master",  
        "roles" : [  
                {  
                        "role" : "userAdminAnyDatabase",  
                        "db" : "admin"  
                }  
        ]  
} 

打开mongodb的验证

net:
  port: 27017
  bindIp : 0.0.0.0  #监听所有ip

security:               
  authorization: enabled  #开启密码验证

用超级用户登录mongo

$mongo   
MongoDB shell version v3.4.10
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.10
>

>use admin
switched to db admin
>db.auth("master","123456")   #用超级用户登录了

去创建一个test库,然后创建test库的账户密码

$mongo   
MongoDB shell version v3.4.10
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.10
>

>use admin
switched to db admin
>db.auth("master","123456")   #用超级用户登录了

>use test
switched to db test
> db.createUser({user: "test",pwd: "test",roles: [{ role: "readWrite", db: "test" }] })  #创建对test库有读写权限的账户密码
Successfully added user: {
    "user" : "test",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "timecash"
        }
    ]
}

测试test库的账户密码是否能登录

$ mongo
MongoDB shell version v3.4.10
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.10
>

>use test
switched to db test
>db.auth("test","test")
1
>db.abc.insert({"a":1,"b":2})  #在test库的abc表插入数据

用test账户直接登录

$ mongo test -u test -p test
MongoDB shell version v3.4.10
connecting to: mongodb://127.0.0.1:27017/timecash
MongoDB server version: 3.4.10
> db
test
