正确备份语句:   mongodump -h 172.27.137.26:36137 -d ssdb -o f:\data\ssdb170505 -u=administrator -p=qqddd.222 --authenticationDatabase=admin

 

 

第一次使用 mongodump -h 172.27.137.26:36137 -d ssdb -o f:\data\ssdb170505 -u=administrator -p=qqddd.222

当备份时报错: 

Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.

需要添加--authenticationDatabase admin
