ubuntu16 kubernetes1.6安装（五、master节点安装）

goodmm

　　下载master节点需要的二进制文件
https://storage.googleapis.com/kubernetes-release/release/v1.6.0/kubernetes-server-linux-amd64.tar.gz
下载后解压，拷贝所有文件
cp -r server/bin/{kube-apiserver,kube-controller-manager,kube-scheduler,kubectl,kube-proxy,kubelet} /usr/local/bin/
按照网传其他文档都设置有其配置的配置文档，其中部分配置参数是错误的或者过时的，可自行参考kube-apiserver --help等，当然安装过程出错能让人更好的理解其组件关系，参数验证可直接拿systemd里的命令加参数运行进行验证。本文都直接添加到systemd启动文件中。

　　依次启动kube master节点的所有组件
systemctl daemon-reload
systemctl enable kube-apiserver
systemctl start kube-apiserver
systemctl status kube-apiserver
systemctl enable kube-controller-manager
systemctl start kube-controller-manager
systemctl enable kube-scheduler
systemctl start kube-scheduler
　　验证master节点
