mongodb 安装及使用
大家好，又见面了，我是全栈君。
一.Windows 平台安装 MongoDB
1.MongoDB 下载
MongoDB 提供了可用于 32 位和 64 位系统的预编译二进制包，你可以从MongoDB官网下载安装，MongoDB 预编译二进制包下载地址：https://www.mongodb.com/download-center/community
2.一步一步默认安装就好，我的安装目录自定义
3.配置环境变量，使在任意位置都可以执行bin下的exe程序
我们设置了环境变量（path）的话,在命令提示符的任何地方都可以使用mongoDB的命令了。
4.设置数据存储目录
D:\softwore\mongodb3\bin>mongod.exe –dbpath D:\softwore\mongodb3\data\db
D:\softwore\mongodb3\bin>mongod.exe --dbpath D:\softwore\mongodb3\data\db

5.链接mongodb
我们可以在命令窗口中运行 mongo.exe 命令即可连接上 MongoDB，执行如下命令：
6.测试
最后：浏览器访问
7.win10设置Mongodb启动为Windows服务自启动
遇到问题：
1.net start MongoDB 服务名无效错误解决
1.将data目录下的所有文件都删除; 2.以管理员模式打开cmd,cd到mongodb bin目录下,运行: mongod –config “D:\Mongo\mongo.conf” –install –serviceName “MongoDB” 再运行: net start MongoDB
2.解决连接mongoDB出现问题：MongoDB : Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused
cmd 命令行以管理员身份运行命令 ：
mongod --config "D:\softwore\mongodb3\mongod.cfg"
