mongodb 备份 指定用户名密码
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
