代码：

# -*- coding:utf-8 -*-

import time import os  DBUSER='myadmin'        #用户

DBPASS='redhat'           #密码

IP='192.168.122.11'        #主机

DATA_DIR='/data'           #目录

PATH_DUMP='/usr/local/mongodb/bin/mongodump'    #命令路径 

BACKITEMS=[     "%s -h %s:27017 -u %s -p %s -o %s" % (PATH,IP,DBUSER,DBPASS,DATA_DIR) ] 

def backData():    

    try:        

        for item in BACKITEMS:            

            print item            

            print os.system(item)    

    except RuntimeError,e:        

        print str(e) 

if __name__=="__main__":

    backData()

代码：

# -*- coding:utf-8 -*-

import time 

import os

DBUSER='myadmin' 

DBPASS='redhat'

IP='192.168.122.1'       #将数据导入改主机

DATA_DIR='/data'

PATH_RES='/usr/local/mongodb/bin/mongorestore'

BACKITEMS=[

    "%s -h %s:27017 --dir %s" % (PATH_RES,IP,DATA_DIR)

]

def backData():

    try:

       for item in BACKITEMS: 

           print item 

           print os.system(item)

    except RuntimeError,e:

        print str(e) 

if __name__=="__main__":

    backData()

运行结果：
