前言
本环境是基于 Centos 7.8 系统构建mongodb-enterprise-4.2.8学习环境
具体构建，请参考 mongodb-enterprise-4.2.8 环境构建
一、数据的导出
生成素材
MongoDB Enterprise > use my_mongodb
switched to db my_mongodb
MongoDB Enterprise > db.createCollection("user")
{
"ok" : 1 }
MongoDB Enterprise > db.user.insertMany(
... [{
id:201,name:'张三',sex:'男',age:19},
... {
id:202,name:'李四',sex:'女',age:22},
... {
id:203,name:'王五',sex:'男',age:20},
... {
id:204,name:'赵六',sex:'女',age:21},
... {
id:205,name:'钱七',sex:'男',age:20}]
... )
{
"acknowledged" : true,
"insertedIds" : [
ObjectId("602d024cf6923c6396ff9c3b"),
ObjectId("602d024cf6923c6396ff9c3c"),
ObjectId("602d024cf6923c6396ff9c3d"),
ObjectId("602d024cf6923c6396ff9c3e"),
ObjectId("602d024cf6923c6396ff9c3f")
]
}
MongoDB Enterprise > db.user.find()
{
"_id" : ObjectId("602d024cf6923c6396ff9c3b"), "id" : 201, "name" : "张三", "sex" : "男", "age" : 19 }
{
"_id" : ObjectId("602d024cf6923c6396ff9c3c"), "id" : 202, "name" : "李四", "sex" : "女", "age" : 22 }
{
"_id" : ObjectId("602d024cf6923c6396ff9c3d"), "id" : 203, "name" : "王五", "sex" : "男", "age" : 20 }
{
"_id" : ObjectId("602d024cf6923c6396ff9c3e"), "id" : 204, "name" : "赵六", "sex" : "女", "age" : 21 }
{

二、数据的导入
# 导入json格式
提前删除数据
MongoDB Enterprise > db.user.drop()
true
MongoDB Enterprise > db.user.find()
MongoDB Enterprise >
导入数据
[root@node01 ~]# mongoimport -d my_mongodb -c user /tmp/user.dat
