首先，在干净的系统上执行如下命令，创建swap文件，并挂载

# 需要root权限
dd if=/dev/zero of=/var/swapfile bs=128M count=32
chmod 600 /var/swapfile
mkswap /var/swapfile
swapon /var/swapfile
swapon -s # 仅在该节点被重新启动后启用该交换内存文件
echo "/var/swapfile swap swap defaults 0 0" >> /etc/fstab

然后根据对应的kubernetes版本选择kubeadm配置文件

配置文件见下面

# kubeadm-config-v1.28.yaml
