在Oracle Cloud Infrastructure Compute节点上打开端口80 [英] Opening port 80 on Oracle Cloud Infrastructure Compute node

问题描述

这是一个基本问题，但是我似乎无法通过阅读Oracle文档来解决.我创建了一个基于Ubuntu的计算节点，并将其连接到子网.在该子网中，我创建了一个有状态规则，其源为0.0.0.0/0，IP协议:TCP，源端口范围:全部，目标端口范围:80.

This is an elementary question however one I cannot seem to resolve by perusing the Oracle documentation. I've created an Ubuntu-based compute node, and it's attached to a subnet. In that subnet I've created a stateful rule with source 0.0.0.0/0, IP protocol: TCP, Source Port Range: All, Destination Port Range: 80.

服务器上没有配置防火墙.

There is no firewall configured on the server.

尽管进行了此配置，但我无法访问计算节点的公共IP.有什么想法吗?

Despite this configuration I can't access the compute node's public IP. Any ideas?

推荐答案

在Oracle Cloud Infrastructure上部署计算实例时，您需要考虑以下几点:

When deploying compute instances at Oracle Cloud Infrastructure you need to take into account few things:

1. 创建Internet网关(IGW).
2. 定义指向IGW的路由.
3. 在安全性列表"中允许与IGW关联的端口80.默认情况下，您只能访问SSH和ICMP 3,4类型.
4. 允许在Compute的实例防火墙上连接(默认情况下已启用).

在您的示例中，如果您使用的是OEL形状:

In your example if you are using a OEL shape:

$ sudo firewall-cmd --zone=public --permanent --add-port=80/tcp

$ sudo firewall-cmd --reload
