#### 安装教程

**生成ssh-key密钥对，并将公钥同步到各节点**

```bash
# 生成密钥对，同时备注信息密钥来源ansible
sh# ssh-keygen -t rsa -f ~/.ssh/k8s_rsa -C "ansible@tentao.tech"

# 将公钥同步到远程主机
sh# ssh-copy-id -i ~/.ssh/k8s_rsa.pub <HOST>
```

**下载升级内核需要的文件**
```bash
# 切换到内核安装包目录
sh# cd playbooks/roles/set_kernel/files/

# 执行脚本下载内核安装包到当前目录
sh# bash kernel_download.sh
```

#### 部署指定版本K8s集群（版本:v1.33.0）

```bash
sh# cd ansible_deploy_k8s/

# 主机清单信息设置
sh# cat <<EOF | tee inventory2.ini 
[k8s_master]
k8s-master01	ansible_host=192.168.20.121
