公司在使用mongodb数据库，相对比较方便，今天需要实现使用RobotMongodb数据库工具，进行导入

导入步骤：

登陆到你的mongodb服务器，我们在liunx上安装所以需要，ssh连接到该服务器上第二步：将文件导入服务器指定目录下；

第三步：进入mongo安装的位置，执行命令：cd mongodb-linux-x86_64-amazon-3.4.4/

第四步：进入bin目录，执行命令：cd bin

第五步：连接服务：执行命令：./mongo 127.0.0.1:20000，显示连接成功，mongo版本即可

第六步：导入备份文件： `

./mongoimport --host=127.0.0.1 --port=20000 --db=myMongoDB --collection=wechat   --file=/mnt/wechat_contacts.dat`

会显示成功导入

connected to: 127.0.0.1:20000
2018-01-19T18:23:42.121+0800    imported 408 documents

测试是否导入成功，执行以下命令

连接服务：./mongo 127.0.0.1:20000
显示数据库：show dbs
显示collection：show collections
查询第一行数据：
db.wechat.findOne()

以下为实际操记录：
