mongoDB学习之旅(一)

首先自己去 https://www.mongodb.org/ 官网下载哦~ 我的是64位的

安装就简单讲下吧...下载个安装包, 随便安装, 只要你找到的...

cmd进去你的安装目录下/bin文件夹...简单的很...

1. 找到“mongodb”的路径，然后运行mongod开启命令，同时用--dbpath指定数据存放地点为“db”文件夹
D:/MongoDB/server/bin> mongod --dbpath=D:/MongoDB/data

2. 再打开一个cmd窗口,进入到bin目录下...
D:/MongoDB/server/bin> mongo
2015-07-07T23:58:30.882+0800 I CONTROL Hotfix KB2731284 or later update is not installed, will zero-out data files
MongoDB shell version: 3.0.4
connecting to: test
默认进入test数据库
3.插入数据:
> db.Person.insert({"name":"helloword","age":"23"});
WriteResult({ "nInserted" : 1 })
提示插入成功!
4.查询数据
4.1 全部查询
> db.Person.find();
{ "_id" : ObjectId("559bf7cb15c09e490e77d072"), "name" : "feiazi", "age" : "22" }
{ "_id" : ObjectId("559bf7da15c09e490e77d073"), "name" : "helloword", "age" : "23" }
{ "_id" : ObjectId("559bf7fa15c09e490e77d074"), "name" : "luojun", "age" : "22" }
4.2 条件查询
> db.Person.find({"name":"luojun"});
{ "_id" : ObjectId("559bf7fa15c09e490e77d074"), "name" : "luojun", "age" : "22" }
