关闭CentOS自带防火墙
systemctl disable firewalld
systemctl stop firewalld
安装 etcd 和 kubernetes 软件
会自动安装docker软件
yum -y install etcd kubernetes
#修改下面配置文件
vim /etc/sysconfig/docker
OPTIONS='--selinux-enabled=false --insecure-registry gcr.io'
#修改下面配置文件
vim /etc/kubernetes/apiserver
KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ResourceQuota"
启动所有服务
systemctl start etcd docker kube-apiserver kube-controller-manager kube-scheduler kubelet kube-proxy
用命令查看k8s是否已经运行
[root@localhost parallels]# kubectl cluster-info
Kubernetes master is running at http://localhost:8080
至此一个单机版kubernetes集群就安装启动完成了
docker，k8s服务启动命令
#关闭
systemctl stop docker
#启动
systemctl start docker
#开机启动
systemctl enable docker
#查看运行状态
systemctl status kubelet
systemctl status docker
错误
Job for kube-apiserver.service failed because the control process exited with error code. See "systemctl status kube-apiserver.service" and "journalctl -xe" for details.
我这里的原因是：端口被占用，修改端口号
vi /etc/kubernetes/apiserver
KUBE_API_PORT="--port=18080"
