Mongoose学习笔记

需要node和MongoDB环境

Mac 安装MongoDB

brew update

brew install mongodb

安装完成后命令行会有提示

第一次启动前需要做一些准备工作：

默认mongodb 数据文件是放到根目录 data/db 文件夹下,如果没有这个文件,请自行创建

mkdir -p /data/db

如果提示没有权限就使用

sudo mkdir -p /data/db

系统目录下需要读写权限，所以我把数据库改到了/User/目录下
找到配置文件

/usr/local/etc/mongod.conf

systemLog:
  destination: file
  path: /usr/local/var/log/mongodb/mongo.log
  logAppend: true
storage:
  dbPath: /Users/你的系统名/work/data/db
net:
  bindIp: 127.0.0.1

似乎配置文件改了也还是读取默认的/data/db路径

之后设置一下环境变量PATH

vi ~/.bash_profile

在配置文件里添加export PATH=<mongodb的安装目录>/bin:$PATH 如：

export PATH=/usr/local/Cellar/mongodb/3.4.10/bin:${PATH}

source ~/.bash_profile // 刷新环境变量

然后通过命令行启动MongoDB：

mongod --dbpath /Users/系统名/work/data/db

这里如果数据库路径默认就可以直接打mongd运行

#####可能报错：

应该是没有读写权限，加权限sudo chown 系统名 /data/db
