私はmongorestoreユーティリティをテストするためにこれを行います
以下は私のテスト手順です:
mongo 127.0.0.1/mytest -u alex -p alex
> db.createCollection("test1")
{ "ok" : 1 }
> db.test1.insert({id:1,name:"alex"})
> db.test1.find()
{ "_id" : ObjectId("519b3d7808b450e533c8ea5e"), "id" : 1, "name" : "alex" }
> show collections;
system.indexes
system.users
test1
testtable
> exit
