无法访问安装在ubuntu18.10上的Jenkins，browser说“xxxxx花了很长时间才做出响应”

Question

初学者的问题。

我刚给詹金斯安装了：

• Ubuntu 18.10最小- google云平台
• 安装Java 8
• 配置为允许从任何地方访问端口80的

当通过互联网从客户端计算机浏览器访问它时，上面写着<server IP address> took too long to respond

运行netstat -apn|grep 80;我得到：

tcp        0      0 10.142.0.3:58216        169.254.169.254:80      ESTABLISHED

Answer 1

解决后，我不仅需要允许来自实例防火墙的通信，还需要允许来自云平台的流量。
