mongodb

一,准备材料

　官网下载MongoDB安装包：http://www.mongodb.org/downloads

　百度云盘下 https://pan.baidu.com/s/1pLTnkld  密码　dvsw

   建议在官网下载避免XCode

   安装完成如图

   　　

 logs 就是一个空文件夹 可以自行创建

 然后创建数据库目录 D:datadb

二,启动服务

打开cmd 切换磁盘目录

执行windows服务安装指令

mongod.exe --logpath D:mongodblogsMongoDB.log --logappend --dbpath D:mongodbdatadb --directoryperdb --serviceName MongoDB --install

出现问题一般是路径有问题。

1）请注意你所有的路径没有错，包括mongod所在路径，日志所在路径等；

2）不要加入多余的“”，如“D:MongoDBData”这个，千万不要写成“D:MongoDBData”

安装完成服务

net start mongodb  启动服务
net stop mongodb   停止服务
sc delete mongodb   删除服务（这条命令适合大多数服务，只需要改后面的服务名称）

删除服务指令

sc delete MongoDB

 三,.NET连接
