python mongodb测试

1.下载pymongo-1.11.win32-py2.6.exe，因python为2.6，安装
2.下载mongodb-win32-i386-1.8.1解压
3.cmd下运行：
   J:\soft\mongodb-win32-i386-1.8.1\mongodb-win32-i386-1.8.1\bin\mongod --dbpath=J:\soft\mongodb-win32-i386-1.8.1\mongodb-win32-i386-1.8.1\data\db
  看到，最后有listening on port 28107，就正常启动服务了
4.新起cmd窗口J:\soft\mongodb-win32-i386-1.8.1\mongodb-win32-i386-1.8.1\bin\mongo.exe
  显示连接，信息与版本就正常了
5.python测试脚本
  

#! /usr/bin/env python
#coding=utf-8
