解决：

 

1. 开放端口
   
   firewall-cmd --zone=public --add-port=6443/tcp --permanent firewall-cmd --zone=public --add-port=2379/tcp --permanent firewall-cmd --zone=public --add-port=2380/tcp --permanent firewall-cmd --zone=public --add-port=10250/tcp --permanent firewall-cmd --zone=public --add-port=10251/tcp --permanent firewall-cmd --zone=public --add-port=10252/tcp --permanent firewall-cmd --zone=public --add-port=30000-32767/tcp --permanent

   1 2 3 4 5 6 7

   firewall-cmd --zone=public --add-port=6443/tcp --permanent firewall-cmd --zone=public --add-port=2379/tcp --permanent firewall-cmd --zone=public --add-port=2380/tcp --permanent firewall-cmd --zone=public --add-port=10250/tcp --permanent firewall-cmd --zone=public --add-port=10251/tcp --permanent firewall-cmd --zone=public --add-port=10252/tcp --permanent firewall-cmd --zone=public --add-port=30000-32767/tcp --permanent

   
    
2. 安装 kubeadmin
   
   cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-\$basearch enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg exclude=kubelet kubeadm kubectl EOF # Set SELinux in permissive mode (effectively disabling it) sudo setenforce 0 sudo sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config sudo yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes sudo systemctl enable --now kubelet

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

   cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-\$basearch enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg exclude=kubelet kubeadm kubectl EOF   # Set SELinux in permissive mode (effectively disabling it) sudo setenforce 0 sudo sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config   sudo yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes   sudo systemctl enable --now kubelet

   
    
3. 手工拉取 docker image , （国内访问不了所以需要手工拉去，否则第四步会报错）
   
   #拉取镜像 docker pull kubesphere/kube-apiserver:v1.18.6 docker pull kubesphere/kube-controller-manager:v1.18.6 docker pull kubesphere/kube-scheduler:v1.18.6 docker pull kubesphere/kube-proxy:v1.18.6 docker pull kubesphere/pause:3.2 docker pull azhu/etcd:3.4.3-0 docker pull coredns/coredns:1.6.7 #修改tag docker tag kubesphere/kube-apiserver:v1.18.6 k8s.gcr.io/kube-apiserver:v1.18.6 docker tag kubesphere/kube-controller-manager:v1.18.6 k8s.gcr.io/kube-controller-manager:v1.18.6 docker tag kubesphere/kube-scheduler:v1.18.6 k8s.gcr.io/kube-scheduler:v1.18.6 docker tag kubesphere/kube-proxy:v1.18.6 k8s.gcr.io/kube-proxy:v1.18.6 docker tag kubesphere/pause:3.2 k8s.gcr.io/pause:3.2 docker tag azhu/etcd:3.4.3-0 k8s.gcr.io/etcd:3.4.3-0 docker tag coredns/coredns:1.6.7 k8s.gcr.io/coredns:1.6.7

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

   #拉取镜像 docker pull kubesphere/kube-apiserver:v1.18.6 docker pull kubesphere/kube-controller-manager:v1.18.6 docker pull kubesphere/kube-scheduler:v1.18.6 docker pull kubesphere/kube-proxy:v1.18.6 docker pull kubesphere/pause:3.2 docker pull azhu/etcd:3.4.3-0 docker pull coredns/coredns:1.6.7   #修改tag docker tag kubesphere/kube-apiserver:v1.18.6  k8s.gcr.io/kube-apiserver:v1.18.6 docker tag kubesphere/kube-controller-manager:v1.18.6 k8s.gcr.io/kube-controller-manager:v1.18.6 docker tag kubesphere/kube-scheduler:v1.18.6 k8s.gcr.io/kube-scheduler:v1.18.6 docker tag kubesphere/kube-proxy:v1.18.6 k8s.gcr.io/kube-proxy:v1.18.6 docker tag kubesphere/pause:3.2 k8s.gcr.io/pause:3.2 docker tag azhu/etcd:3.4.3-0 k8s.gcr.io/etcd:3.4.3-0 docker tag coredns/coredns:1.6.7 k8s.gcr.io/coredns:1.6.7

   
    
4. kubeadm init
   
   kubeadm init --pod-network-cidr=192.168.0.0/16 --service-cidr=172.10.0.0/16 --image-repository registry.aliyuncs.com/google_containers

   1	kubeadm init --pod-network-cidr=192.168.0.0/16 --service-cidr=172.10.0.0/16  --image-repository registry.aliyuncs.com/google_containers

   
    
5. config kubectl
   
   scp root@d1:/etc/kubernetes/admin.conf .\.kube\config

   1	scp root@d1:/etc/kubernetes/admin.conf  .\.kube\config

   
    
6. 允许 master 节点执行 pod （单节点必备）
   
   kubectl taint nodes --all node-role.kubernetes.io/master-

   1	kubectl taint nodes --all node-role.kubernetes.io/master-

   
    
7. 配置网络
   
   kubectl create -f https://docs.projectcalico.org/manifests/tigera-operator.yaml

   1	kubectl create -f https://docs.projectcalico.org/manifests/tigera-operator.yaml

   
    
8. add node
