使用ifconfig返回了这样的数据：

ifconfig
<span style="color:#ffd700">ens33</span>: flags=<span style="color:#f5ab35">4163</span>&amp;lt;UP,BROADCAST,RUNNING,MULTICAST&amp;gt; mtu <span style="color:#f5ab35">1500</span>

可以知道虚拟机的ip是：

<span style="color:#f5ab35">192.168.187.133</span>

在外部可以使用以下来访问3000端口的yarn 项目

<span style="color:#f5ab35">192.168.187.133:3000</span>
