MongoDB导入导出

1、单库导出

./mongodump -h ip:port -u username -p password -d databasename -o pathToSave
示例

./mongodump -h 127.0.0.1:27017 -u uname -p pwd -d my_demo -o ../databak/

2、单库还原

./mongorestore -h ip:port  -u uname -p pwd -d  databasename path/my_demo [--drop]

./mongorestore -h ip:port  [--authenticationDatabase admin -u admin -p adminpwd] -d  databasename path/my_demo [--drop]

错误示例

./mongorestore -h 127.0.0.1:27017 -d my_demo ../databak/my_demo （×错误）

报错信息：the the --db and --collection args should only be used when restoring from a BSON file. Other uses are deprecated and will not exist in the future; use --nsInclude instead

正确示例

• 不删除原有数据的还原

./mongorestore -h 127.0.0.1:27017 -u uname -p pwd -d my_demo ../databak/my_demo (√正确)

• 删除原有数据的还原，加 --drop

./mongorestore -h 127.0.0.1:27017 -u uname -p pwd -d my_demo ../databak/my_demo --drop (√正确)

• 如果还原的时候报权限问题，需要加上管理员的账号密码 --authenticationDatabase admin -u admin -p adminpwd

auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-1": (AuthenticationFailed) Authentication failed.

./mongorestore -h 127.0.0.1:27017 --authenticationDatabase admin -u admin -p adminpwd -d my_demo ../databak/my_demo --drop
