在另1个端口导入。

先在这个端口创建服务，用户

./mongod --port27019 --dbpath /home/mongodb/mongodbsoft/data27019 --logpath/home/mongodb/mongodbsoft/log27019/

./mongo --port27019

> use bamuta

> db.addUser ("bamuta","bamuta");

然后导入

[mongodb@pera bin]$ ./mongorestore-d bamuta --port 27019 /home/mongodb/backupdmp/bamuta
