报错1：文件存在

error execution phase preflight: [preflight] Some fatal errors occurred: [ERROR FileAvailable–etc-kubernetes-manifests-kube-apiserver.yaml]: /etc/kubernetes/manifests/kube-apiserver.yaml already exist

这个报错是因为重复安装引起，执行重置命令即可。

kubeadm reset

非部署节点 resfuse

普通节点执行安装网络插件命令时报错

The connection to the server localhost:8080 was refused - did you specify the right host or port?

kubectl命令需要使用kubernetes-admin来运行，需要admin.conf文件（conf文件是通过“ kubeadmin init”命令在主节点/etc/kubernetes 中创建），但是从节点没有conf文件，也没有设置 KUBECONFIG =/root/admin.conf环境变量，所以需要复制conf文件到从节点，并设置环境变量就OK了

# 主节点把配置文件copy到这个节点
scp /etc/kubernetes/admin.conf  node:/etc/kubernetes/
# node节点执行
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
