KubeSphere 高可用集群搭建并启用所有插件

介绍

大多数情况下，单主节点集群大致足以供开发和测试环境使用。但是，对于生产环境，您需要考虑集群的高可用性。如果关键组件（例如 kube-apiserver、kube-scheduler 和 kube-controller-manager）都在同一个主节点上运行，一旦主节点宕机，Kubernetes 和 KubeSphere 都将不可用。因此，您需要为多个主节点配置负载均衡器，以创建高可用集群。您可以使用任意云负载均衡器或者任意硬件负载均衡器（例如 F5）。此外，也可以使用 Keepalived 和 HAproxy，或者 Nginx 来创建高可用集群。

架构

在您开始操作前，请确保准备了 6 台 Linux 机器，其中 3 台充当主节点，另外 3 台充当工作节点。下图展示了这些机器的详情，包括它们的私有 IP 地址和角色。

配置负载均衡器

您必须在您的环境中创建一个负载均衡器来监听（在某些云平台也称作监听器）关键端口。建议监听下表中的端口。

服务协议端口

apiserver TCP 6443

ks-console TCP 30880

http TCP 80

https TCP 443
