一、mac安装MongoDB
使用的是mac，所以直接使用homebrew安装了
1、打开控制台，输入下列代码安装
brew install mongodb
如果出现一下代码，即表示安装到本地完毕
Updating Homebrew...
==> Downloading https://homebrew.bintray.com/bottles/mongodb-4.0.3_1.mojave.bott
Already downloaded: /Users/gaoshang/Library/Caches/Homebrew/downloads/0496c82a6b2d3e5970ab2cbc97c3a19acba625a8ab1e008b9ad35b41e2a507a7--mongodb-4.0.3_1.mojave.bottle.tar.gz
==> Pouring mongodb-4.0.3_1.mojave.bottle.tar.gz
==> Caveats
To have launchd start mongodb now and restart at login:
brew services start mongodb
Or, if you don't want/need a background service you can just run:
mongod --config /usr/local/etc/mongod.conf
==> Summary
🍺 /usr/local/Cellar/mongodb/4.0.3_1: 18 files, 258.1MB
mongo的配置文件位置：/usr/local/etc/mongod.conf
mongodb的安装位置默认在homebrew的应用安装位置：/usr/local/Cellar/mongodb/4.0.3_1
2、在环境变量中配置mongo的bin路径
输入以下代码，进入环境配置文件中
vim .bash_profile
输入i 然后拷贝下面的代码进去 然后输入：wq 退出
export PATH=/usr/local/Cellar/mongodb/4.0.3_1/bin:${PATH}
根据上面👆安装的版本在上述代码中改一下自己的版本号，以免后续版本号错误找不到
3、在本机home目录新建两个文件夹/data/db并设置权限
因为mongo启动需要找到这个文件夹存数据
安装位置自己知道就好不需要非在home目录下，只要后续记住自己创建的文件夹位置就好
输入以下代码 并输入本机密码
sudo mkdir -p /data/db
输入以下代码 并输入本机密码 给该文件夹分配权限(以下命令分配所有权限)
sudo chown /data/db
4、启动mongodb服务端
输入以下命令
mongod
如果出现以下代码 即表示成功 成功后不要关闭窗口

开启后不要关闭该端口！！！
5、启动客户端
新建一个窗口 command+N 输入以下代码
mongo
出现下列代码即表示启动成功

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
