1.安装MongoDB
brew install mongodb
这个是默认安装最新版本的 mogodb,如果想安装指定版本可以先查看 mongodb 版本
brew search mongodb
mongodb ✔ mongodb@3.2 mongodb@3.6
mongodb@3.0 mongodb@3.4 percona-server-mongodb
选择安装3.6版本
brew install mongodb@3.6
不同的环境会遇到不同的问题,比如安装路径权限,请查看 python开发遇到的坑(2)mongodb安装路径权限问题
2.启动MongoDB服务：
brew services start mongodb@3.6
==> Tapping homebrew/services
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-services'...

Tapped 1 command (44 files, 58.7KB).
==> Successfully started `mongodb@3.6` (label: homebrew.mxcl.mongodb@3.6)
3.关闭MongoDB服务
brew services stop mongodb@3.6
Stopping `mongodb@3.6`... (might take a while)
==> Successfully stopped `mongodb@3.6` (label: homebrew.mxcl.mongodb@3.6)
4.MongoDB的配置
（1）创建根目录下 data/mongodb 文件夹：
mkdir -p /data/mongodb
提示:mkdir: /data/mongodb: Permission denied
sudo mkdir -p /data/mongodb
然后输入密码
（2）给 /data/mongodb 文件夹赋予权限：
sudo chown id -u /data/mongodb
提示:chown: id: illegal user name
whoami
sudo chown username /data/mongodb
（3）添加环境变量：
vim ~/ .zshrc
添加 mongodb 安装路径到 PATH export PATH=/usr/local/Cellar/mongodb/3.4.6/bin:${PATH}
温馨提示vim命令:
进入vim编辑页面,i:键入,esc:退出编辑,:wq 保存然后退出编辑
（4）修改 MongoDB 配置文件, 配置文件默认在 /usr/local/etc 下的 mongod.conf：
systemLog:
destination: file
path: /usr/local/var/log/mongodb/mongo.log
logAppend: true
storage:
dbPath: /usr/local/var/mongodb
net:
bindIp: 127.0.0.1
（5）启动服务端：
$ mongod
