环境初始化和安装 keepalibed、haproxy

设置yum源，可以查看Linux安装部署docker博客文章。（安装在所有节点）

设置环境初始化，可以查看Linux安装部署高可用k8s集群博客文章。（安装在相应的节点）。

验证安装

  • 查看日志

    1
    kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f

  • 访问 Web 控制台

    通过 NodePort (IP:30880)(所有的节点机器的IP包括虚拟IP) 使用默认帐户和密码 (admin/P@88w0rd) 访问 Web 控制台

    You need to specify one of the following:

断电重启 KubeSphere

  • 关闭交换区

    1
    swapoff -a

  • k8s节点会自动重启，node节点需要重新加入master
