1.2、MongoDB基本概念解析

1.3、MongoDB中的数据存储结构

通过下图实例，我们也可以更直观的了解 Mongo 中的一些概念：

1.4、MongoDB启动服务

1、启动 MongoDB 服务

[atguigu@node001 mongodb-5.0.2]$ pwd
/opt/module/mongoDB/mongodb-5.0.2
[atguigu@node001 mongodb-5.0.2]$ bin/mongod --bind_ip 0.0.0.0

2、进入 shell 页面

[atguigu@node001 bin]$ pwd
/opt/module/mongoDB/mongodb-5.0.2/bin
[atguigu@node001 bin]$ /opt/module/mongoDB/mongodb-5.0.2/bin/mongo

5）启动 MongoDB 服务
[atguigu@hadoop102 mongodb]$ bin/mongod
6）进入 shell 页面
[atguigu@hadoop102 mongodb]$ bin/mongo
[atguigu@node001 mongodb-5.0.2]$ pwd
/opt/module/mongoDB/mongodb-5.0.2
[atguigu@node001 mongodb-5.0.2]$ sudo mkdir -p /data/db/
[atguigu@node001 mongodb-5.0.2]$ sudo mkdir -p /opt/module/mongoDB/mongodb-5.0.2/data/db/
[atguigu@node001 mongodb-5.0.2]$ sudo chmod 777 -R /data/db/
[atguigu@node001 mongodb-5.0.2]$ sudo chmod 777 -R /opt/module/mongoDB/mongodb-5.0.2/data/db/
[atguigu@node001 mongodb-5.0.2]$ bin/mongod
[atguigu@node001 bin]$ /opt/module/mongoDB/mongodb-5.0.2/bin/mongo
MongoDB shell version v5.0.2
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("b9e6b776-c67d-4a8d-8e31-c0350850065e") }
MongoDB server version: 5.0.2
================
Warning: the "mongo" shell has been superseded by "mongosh",
which delivers improved usability and compatibility.The "mongo" shell has been deprecated and will be removed in
an upcoming release.
We recommend you begin using "mongosh".
For installation instructions, see
https://docs.mongodb.com/mongodb-shell/install/
================
Welcome to the MongoDB shell.
For interactive help, type "help".

---Enable MongoDB's free cloud-based monitoring service, which will then receive and displaymetrics 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 youand anyone you share the URL with. MongoDB may use this information to make productimprovements 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()

2、DataX导入导出案例

2.1、读取MongoDB的数据导入到HDFS

2.1.1、mongodb2hdfs.json
