安装单机版k8s

1、配置yum源，博主使用华为的镜像源

　 　

　　选择不同的系统版本下载使用：

 2、安装etcd，kubernetes

　　yum -y install etcd kubernetes

3、修改kubernetes的配置

     vim   /etc/kubernetes/apiserver

　　

 4、安装rhsm,否则启动pod的时候镜像无法下载

　　 1) yum -y install *rhsh*

　　 2) wget http://mirror.centos.org/centos/7/os/x86_64/Packages/python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm

       3)  rpm2cpio python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm | cpio -iv --to-stdout ./etc/rhsm/ca/redhat-uep.pem | tee /etc/rhsm/ca/redhat-uep.pem

5、启动各个服务

systemctl start etcd
systemctl start docker
systemctl start kube-apiserver
systemctl start kube-controller-manager
systemctl start kube-scheduler
systemctl start kubelet
systemctl start kube-proxy

并且执行以下代码：docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest (博主翻阅遇坑，自己在网上找的答案)

6、验证启动一个deploment
