使用shell和mongoShell结合解决问题！

解决问题:通过js脚本将格林威治时间转换成北京时间,并且推送给需求方。

# 时间转换为纯数字

startTime=`date -d "-1  day" "+%Y-%m-%d 00:00:00"`

endTime=`date "+%Y-%m-%d 00:00:00"`

st=$((`date --date "$startTime" +"%s"` * 1000))

et=$((`date --date "$endTime" +"%s"` * 1000))

#将数据从primary中导出(注意不要使用--csv,否则到导入的时候会报错)

mongoexport --host=10.136.3.117 --port=27017 --authenticationDatabase=admin --username=root [email protected] --db=gow --collection=playerlogs --query="{start:{\$gte:new Date($st),\$lt:new Date($et)}}"  -f userId,start  --out=/home/backup/playerlogs.csv

mongoexport --host=10.136.3.117 --port=27017 --authenticationDatabase=admin --username=root [email protected] --db=gow --collection=signinlogs --query="{time:{\$gte:new Date($st),\$lt:new Date($et)}}"  -f user,time   --out=/home/backup/signinlogs.csv

mongoexport --host=10.136.3.117 --port=27017 --authenticationDatabase=admin --username=root [email protected] --db=gow --collection=traderecords --query="{tradeTime:{\$gte:new Date($st),\$lt:new Date($et)}}"  -f userId,amount,tradeTime    --out=/home/backup/traderecords.csv

cd  /home/backup

#将文件传送到目标服务器

scp  playerlogs.csv  [email protected]:/home/backup/

scp  signinlogs.csv  [email protected]:/home/backup/

scp  traderecords.csv  [email protected]:/home/backup/

###############这个时候需要切换到另外一台机器上===========

#导入数据
