shell连接mongodb的命令mongo
$ mongo MongoDB shell version v3.6.2connecting to: mongodb://127.0.0.1:27017MongoDB server version: 3.6.2Server has startup warnings:2018-08-05T14:29:13.960+0800 I CONTROL [initandlisten]2018-08-05T14:29:13.960+0800 I CONTROL [initandlisten] ** WARNING: Access control is not enabled for the database.2018-08-05T14:29:13.960+0800 I CONTROL [initandlisten] ** Read and write access to data and configuration is unrestricted.2018-08-05T14:29:13.960+0800 I CONTROL [initandlisten]连接mongo
默认连接本地mongo
from pymongo import MongoClient client =MongoClient()
参数形式连接mongo
client = MongoClient(host='IP', port=27017) #端口号默认为27017是数值
URI形式连接mongo
client = MongoClient('mongodb://IP:27017')创建数据库#创建数据库，两种方式db = client.peopleinfo db = client['peopleinfo']
连接pydb数据库
import pymongo client = pymongo.MongoClient(host='localhost', port=27017) db = client['pydb']创建数据表
和数据库一样，下面两种方式都可以
t = db.stu t = db['stu']插入数据
stu.insert({'_id':3,'name':'mog','age':20})修改数据stu.update({'_id':3},{'$set':{'name':'mongo'}})查询数据for cur in stu.find({'age':{'$gte':20}}): print(cur)删除数据stu.delete_one({'_id':'2'})
