systemctl disable firewalld
systemctl stop firewalld

yum install -y etcd kubernetes

安装过docker 版本不支持
需要卸载重新安装
1、查看安装过的docker：yum list installed | grep docker

2、卸载docker：yum remove -y docker-ce.x86_64

3、删除容器镜像：rm -rf /var/lib/docker

按顺序启动所有的服务
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
systemctl start 
systemctl restart etcd kube-apiserver kube-controller-manager kube-scheduler

配置aliyun镜像加速
https://cr.console.aliyun.com/cn-hangzhou/mirrors
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://*****.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

创建rc
kubectl create -f mysql-rc.yaml
kubectl get rc
kubectl get pods

kubectl describe rc mysql


kubectl create -f redis-master-rc.yaml
kubectl create -f redis-master-service.yaml

  kubectl cp  boss_post_details nginx-fc5bdb9dc-th6kf:/static/share
 
 kubectl cp  share nginx-79b7f44c97-xvmcr:/static/
