将集合user从192.168.1.12:27017导入到192.168.1.120:27017

数据的导出：mongoexport

数据的导入：mongoimport

导出集合user的过程：

[root@prod01 ]#cd /data/package/mongodb/bin

[root@prod01 bin]# ./mongoexport -h192.168.1.12:27017 --username=root --password=xxxxxx --authenticationDatabase=admin -d userinfo -c user -o user.dat

导出文件位于bin目录

-h, --host=<hostname> mongodb host to connect to (setname/host1,host2 for replica sets)
　　--port=<port> server port (can also use --host hostname:port)

-u, --username=<username> username for authentication
-p, --password=<password> password for authentication
　　--authenticationDatabase=<database-name> database that holds the user's credentials
　　--authenticationMechanism=<mechanism> authentication mechanism to use

-d, --db=<database-name> database to use
-c, --collection=<collection-name> collection to use

-o, --out=<filename> output file; if not specified, stdout is used
--jsonArray output to a JSON array rather than one object per line
--pretty output JSON formatted to be human-readable
--noHeaderLine export CSV data without a list of field names at the first line

导入集合：

./mongoimport -h192.168.1.120:27017 --username=root --password=xxxxxx --authenticationDatabase=admin -d userinfo -c user user.dat
