1）连接mongodb

写配置文件 db.cnf

[mode]

modetype = type1

[type1]

ip = 235.235.235.235

port = 27017

user = admin

password = admin

[type2]

ip = 255.255.255.255

port = 1010

user = fglee_ldq

password = 123456

写初始化文件 dbclass.py

#encoding=utf8

from pymongo import *

from ConfigParser import ConfigParser

class MongoInit(object):

def __init__(self,configFileName="db.cnf"):

self.readConfig(configFileName)

def readConfig(configFileName):

cp = configParser()

cp.read(configFileName)

self.modetype = cp.get("mode","modetype")

self.ip = cp.get(self.modetype,"ip")

self.port = int(cp.get(self.modetype,"port")

self.user = cp.get(self.modetype,"user")

self.password = cp.get(self.modetype,"password")

def initdb(self):

db = MongoClient(self.ip,self.port,read_preference=ReadPreference.SECONDARY_PREFERRED)

#db.admin.authenticate(self.user, self.passwd)

return db

if __name__ == "__main__":

obj = MongoInit("db.cnf")

db = obj.initdb()
