CentOS kubernetes单机部署
1、关闭防火墙
systemctl disable firewalld
systemctl stop firewalld
2、安装etcd和kubernetes软件(会自动安装docker)
yum install -y etcd kubernetes
** 需要修改两处配置：**
- Docker 配置文件/etc/sysconfig/docker , OPTIONS='--seliunx-enabled=false --insecure-registry gcr.io'
- kubernetes apiservce 配置文件/etc/kubernetes/apiserver,把--admission_control参数中的ServiceAccount删除。
3、按下面的顺序启动所有服务：
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
** 安装完成:**
ps -ef|grep kube查看一下。
停止：
systemctl stop kube-proxy
systemctl stop kubelet
systemctl stop kube-scheduler
systemctl stop kube-controller-manager
systemctl stop kube-apiserver
systemctl stop docker
systemctl stop etcd
可以开始使用了！
