yum makecache

安装MongoDB

yum -y install mongodb-org

创建数据库和集合

import pymongo
 
myclient = pymongo.MongoClient("mongodb://localhost:27017/")

#有密码的连接方式
myclient = pymongo.MongoClient("mongodb://root:[email protected]:12307/")
mydb = myclient["runoobdb"] 
mycol = mydb["sites"]

向集合中插入数据

import pymongo
 
mydict = { "name": "RUNOOB1", "alexa": "10000", "website": "https://www.runoob.com","bing":"sss"}
x = mycol.insert_one(mydict)

"""
mylist = [
  { "name": "Taobao", "alexa": "100", "url": "https://www.taobao.com" },
  { "name": "QQ", "alexa": "101", "url": "https://www.qq.com" },

  { "name": "Github", "alexa": "109", "url": "https://www.github.com" }
]
"""
#x = mycol.insert_many(mylist)

查询集合中的数据

import pymongo
 
for x in mycol.find():
	print(x)

查询指定数据

import pymongo
 
myquery = { "name": "RUNOOB1" }
info = mycol.find(myquery)
for x in info:
	print(x)
