主要记录下在mongo 3.0的操作
备份示例
./mongodump -h localhost -d liongo -o ./
还原示例
错误方式：
./mongorestore -h 127.0.0.1 -d liongo --directoryperdb /home/zhoudazhuang/company-zhoudazhuang/liongo/note.bson
会报错：
2017-01-27T15:31:54.217+0800 error parsing command line options: --dbpath and related flags are not supported in 3.0 tools. See http://dochub.mongodb.org/core/tools-dbpath-deprecated for more information 2017-01-27T15:31:54.217+0800 try 'mongorestore --help' for more information
使用mongorestore –help,正确还原方式为（去掉–directoryperdb）：
./mongorestore -h 127.0.0.1 -d liongo /home/zhoudazhuang/company-zhoudazhuang/liongo/note.bson --drop
