我正在遵循https://fuga.cloud/academy/tutorials/ha-vip-with-corosync-on-openstack/中的步骤。
我错过了为什么进入外部浮动 IP 的流量没有正确到达绑定到相关网络端口的机器上的原因。
下面的代码将创建：
- 3 台具有外部 ips 的 LB 机器（curl port80 显示 nginx 响应）
- 3 个额外的网络端口，用于内部故障转移 IP 10.0.0.20{1,2,3}
- 3 个额外的外部 IP 绑定到这些网络端口（curl port80 超时）
在内部 ping/curl 10.0.0.20{1,2,3} ips 工作得很好。但是，如果我尝试通过外部 IP 访问它 - 超时。此外：tcpdump 显示没有流量到达机器上。
负载均衡器网络端口和机器创建：
