mongoDB学习笔记一

Windows上安装mongoDB

下载地址:https://www.mongodb.org/downloads

双击安装-->next-->next-->custom-->设置安装目录(h:\MongoDB\)

运行mongonDB,根目录下创建\data\db目录

Cmd 进入安装根目录,执行如下命令

mongod.exe --dbpath h:\MongoDB\data

出现如下错误:

exception in initAndListen: 28663 Cannot start server. The default is not available with this build of mongod. Please specify a different storage engine explicitly, e.g. --storageEngine=mma

执行如下命令:

mongod.exe --dbpath h:\MongoDB\data--storageEngine=mmapv1

看到如下结果:

H:\MongoDB\Server\3.2\bin>mongod.exe --dbpath h:\MongoDB\data --storageEngine=mmapv1

创建mongoDB服务

方法一:

Cmd-->ctrl+shiift+enter(以管理员身份运行)

创建数据和日志服务

创建配置文件

H:\MongoDB>mkdir h:\MongoDB\data\db

H:\MongoDB>mkdir h:\MongoDB\data\log

创建配置文件

根目录下创建mongod.cfg文件,添加如下内容:

systemLog:

destination: file

path: H:\MongoDB\data\log\mongod.txt

storage:

dbPath: H:\MongoDB\data\db

安装服务

mongod.exe --config h:\MongoDB\mongod.cfg --install --serviceName MongoDB

第二种方法

sc.exe create MongoDB binPath= "\"h:\MongoDB\bin\mongod.exe\" --service --config=\"h:\MongoDB\mongod.cfg\"" DisplayName= "MongoDB" start= "auto"

开启服务

Net start MondoDB

关闭服务

Net stop MonDB

删除服务

方式一:

mongod.exe--remove

方式二:

sc.exe delete MongoDB
