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
