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

启动Mongodb

mongod

可能会遇到报错，shutting down with code:100:

这是因为mongodb的默认数据写入目录是/data/db，需要自己新建一个：

$ mkdir -p /data/db
mkdir: /data/db: Permission denied (没有权限拒绝访问)
// sudo 并输入密码，重新新建目录
$ sudo mkdir -p /data/db
Password:

然后对目录赋予当前系统账户权限

sudo chown -R 系统账户 /data

再执行mongodb：

启动成功！
同时，再执行mongo，进入mongodb命名行模式：

试一下查看数据库show dbs：

admin   0.000GB
config  0.000GB
local   0.000GB
>

另外，mongodb的配置文件地址是/usr/local/etc/mongod.conf

导入JSON

mongoimport -d 数据库名 -c 表名 文件.json

查询一下：

use 数据库
db.表名.find().pretty()
