我是不熟悉容器worrld的，正在尝试在两个Linux VM中本地设置kubernetes集群。在集群初始化期间，它停留在
[apiclient]创建的API客户端，等待控制平面 准备好
我已按照飞行前检查步骤进行操作

Kuberneter版本：
kubeadm-1.6.0-0.x86_64.rpm
kubectl-1.6.0-0.x86_64.rpm
kubelet-1.6.0-0.x86_64.rpm
kubernetes-cni-0.6.0-0.x86_64.rpm
cri-tools-1.12.0-0.x86_64.rpm
如何调试问题或kube版本是否存在版本不匹配。在我使用google.cloud.repo安装yum -y install kubelet kubeadm kubectl之前，同样的工作原理。
由于某些防火墙问题，我无法使用存储库。因此，使用rpm安装。
执行以下命令后， journalctl -xeu kubelet
