我需要从MongoDB(托管在MongoHQ // Compose.io上)实例导出一些信息。我按照these说明操作,这些说明提供了我需要的所有示例,并且似乎与官方mongo文档相对应。这是我正在运行的命令:
mongoexport -h kahana.mongohq.com:12345/my_db_name -u username -p password -d my_db -c usercollection -f "firstName,lastName,macIdNum,iclass" --csv
和输出:
2014-09-17T21:58:12.806-0500 starting new replica set monitor for replica set kahana.mongohq.com:10043 with seeds my_db_name:27017

couldn't connect to [kahana.mongohq.com:12345/my_db_name] connect failed to replica set kahana.mongohq.com:12345/my_db_name:27017
不确定这里的问题是什么。任何帮助将不胜感激!
答案 0 :(得分:7)
这应该有效:
mongoexport -h kahana.mongohq.com:12345 -u username -p password -d my_db -c usercollection -f "firstName,lastName,macIdNum,iclass" --csv
' -h' hostname选项仅用于指定' hostname / IP:port'。
