Enable MongoDB's free cloud-based monitoring service, which will then receive and display  
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you  
and anyone you share the URL with. MongoDB may use this information to make product  
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()  
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

# docker中安装mongo #

[https://blog.csdn.net/meibo69631310/article/details/79709500][https_blog.csdn.net_meibo69631310_article_details_79709500]

docker pull  mongo

docker run  --name some-mongo   -p 27017:27017   -d mongo   --auth     //这里的--name 放在前面并映射端口

docker    exec  -it  容器ID   /bin/bash     //进入容器

mongo

use admin

db.createUser(\{user:"root",pwd:"root",roles:\[\{role:'root',db:'admin'\}\]\})   //创建用户,此用户创建成功,则后续操作都需要用户认证

exit

测试:

mongo  宿主机ip/admin  -utest -p

查看连接是否成功

默认mongodb是不使用用户认证。

show dbs

如果出现not authorized on admin to execute command \{ listDatabases: 1.0, $db: \\"admin\\" \}错误，那就进行用户认证

use admin

db.auth("root","root")

返回 1 认证成功。
