# 1，下载安装包 #

root@wang-GA-MA770T-UD3P:/home/wang/Downloads/k8s# ls
    etcd-v3.3.10-linux-amd64.tar.gz       kubernetes-node-linux-amd64.tar.gz    kubernetes.tar.gz
    kubernetes-client-linux-amd64.tar.gz  kubernetes-server-linux-amd64.tar.gz

解压etcd , server包，并把可执行文件复制到： /k8s/目录的bin 下

root@wang-GA-MA770T-UD3P:/home/wang/Downloads/k8s# ls /k8s/bin/
    apiextensions-apiserver   etcd     hyperkube  kube-aggregator  kube-controller-manager  kubelet     kube-scheduler
    cloud-controller-manager  etcdctl  kubeadm    kube-apiserver   kubectl                  kube-proxy

# 2，创建配置文件：service, conf #

#环境变量
    echo 'PATH=$PATH:/k8s/bin/'>>/etc/profile
    source /etc/profile
