Python简单操作MongoDB

使用程序操作mongodb

mongodb可以使用java、python、php等语言去操作

运维使用Python居多，介绍使用python操作Mongodb数据库

使用python操作mongodb，需要使用pip安装pymongo模块

yum install epel-release -y

yum install python2-pip -y

pip install pymongo

连接代码，单实例的连接代码

import pymongo

client = pymongo.MongoClient( '127.0.0.1', 27017 )

shijiange=client.shijiange

myuser = shijiange.myuser

for item in myuser.find():

  print(item)

pymongo副本集的连接代码，代码支持自动切换

import pymongo

client = pymongo.MongoClient( ['127.0.0.1:27017', '127.0.0.1:27018', '127.0.0.1:27019'] )

shijiange = client.shijiange

myuser = shijiange.myuser

myvar = {'age':20, 'name': 'shijiange'}

myuser.insert(myvar)

for item in myuser.find():

  print(item)

副本集的搭建配置文档

systemLog:  

  destination: file  

  logAppend: true  

  path: /data/mongodb/27017/mongodb.log

storage:  

  dbPath: /data/mongodb/27017/  

journal:    
  enabled: true

processManagement:  

  fork: true

net:  

  port: 27017  

  bindIp: 0.0.0.0

replication:  

  replSetName: shijiange

副本集的mongo命令

config = { _id:"shijiange", members:[

  {_id:0,host:"127.0.0.1:27017"},

  {_id:1,host:"127.0.0.1:27018"},

  {_id:2,host:"127.0.0.1:27019"}]

}

use admin

rs.initiate( config )
