导入MongoDB示例数据

在学习/测试 MongoDB 中，通常我们需要一定的测试数据，本文使用 mongorestore 将示例数据导入到文档数据库 MongoDB 中。

1. 下载示例数据

使用如下命令将示例数据下载到具有 mongorestore 的客户端机器上

wget https://atlas-education.s3.amazonaws.com/sampledata.archive

关于示例数据的说明，可以参考文档[1]。

2. 使用 mongorestore 进行导入

恢复 archive 形态的备份文件时，需要加上 --archive 参数

(base) [root@rudonx ~]# mongorestore --uri=mongodb://root:xxxxxx@xxxxx.mongodb.ivolces.com:3717 --drop --archive=mongo-sampledata/sampledata.archive
