k8s-master节点的虚拟机环境弄好之后，这小节继续介绍k8s-node1 和 k8s-node2节点虚拟机环境安装。
| 节点 | 主机名 | ip |
| 主节点 | k8s-master | 172.31.0.10 |
| 节点1 | k8s-node1 | 172.31.0.11 |
| 节点2 | k8s-node2 | 172.31.0.12 |
- 在D:\vagrant目录下新建centos_stream_9_node1文件夹，然后在文件夹中新建Vagrantfile文件。
centos_stream_9_node1节点的Vagrantfile文件内容如下：

- 在D:\vagrant\centos_stream_9_node2目录这里点击一下，然后输入"cmd"，在弹出的cmd命令框中输入:"vagrant up"命令，进行虚拟机创建。
- 等待两个虚拟机创建完成
现在我们就创建好k8s-node1节点(172.31.0.11)和k8s-node2节点(172.31.0.12)的虚拟机了，它们两个虚拟机root账号的密码都是：1TdhblkFcdhx2a
- 使用ssh工具MobaXterm连接k8s-node1节点(172.31.0.11)和k8s-node2节点(172.31.0.12)
现在，我们就配置好k8s-node1和k8s-node2节点的虚拟机，并在两台虚拟机中安装好Docker。
接下来，我们要在k8s-master上面 安装 kubeadm，然后用 kubeadm 安装k8s集群。
请看下一篇文章：
1.3、k8s-master上面安装 kubeadm-CSDN博客
