可以看里面有个提示信息：

这是缺失/db文件目录 解决方法在终端输入如下命令创建目录：
sudo mkdir -p /data/db
错误2:
然后继续执行gongod命令 发现报错如下：
localhost:~ mengwang$ mongod

这是由于刚刚创建的目录没有读写权限，输入命令设置读写权限：
sudo chmod -R go+w /data/db
然后在执行mongod命令 服务就启动成功了。
可以在浏览器输入http://localhost:27017测试一下 会在网页输出
It looks like you are trying to access MongoDB over HTTP on the native driver port
