bin]# supervisorctl update
bin]# supervisorctl status
# 起来了4个
bin]# ln -s /opt/kubernetes/server/bin/kubectl /usr/bin/kubectl
# 查看集群健康情况，21/22机器：
bin]# kubectl get cs
ln -s ：建立软链接
supervisorctl status ：查看supervisor的情况
supervisorctl update ：更新supervisor
kubectl get ：获取列出一个或多个资源的信息
- 上面一条命令的意思是： 列出所有cs信息
