公司在使用mongodb資料庫，相對比較方便，今天需要實現使用RobotMongodb資料庫工具，進行匯入

匯入步驟：

• 登陸到你的mongodb伺服器，我們在liunx上安裝所以需要，ssh連線到該伺服器上
• 第二步：將檔案匯入伺服器指定目錄下；

• 第三步：進入mongo安裝的位置，執行命令：cd mongodb-linux-x86_64-amazon-3.4.4/

• 第四步：進入bin目錄，執行命令：cd bin

• 第五步：連線服務：執行命令：./mongo 127.0.0.1:20000，顯示連線成功，mongo版本即可
  第六步：匯入備份檔案： `

./mongoimport --host=127.
 
0.0.1 --port=20000 --db=myMongoDB --collection=wechat   --file=/mnt/wechat_contacts.dat`   

會顯示成功匯入

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

• 測試是否匯入成功，執行以下命令

連線服務：./mongo 127.0.0.1:20000
顯示資料庫：show dbs
顯示collection：show collections
查詢第一行資料：
db.wechat.findOne()

以下為實際操記錄：
