<code>systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config</code>

<code>swapoff -a
sed -i '/swap/s/^/#/g' /etc/fstab</code>

<code>hostnamectl set-hostname k8s-master
hostnamectl set-hostname k8s-node1
hostnamectl set-hostname k8s-node2</code>

<code>yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce docker-ce-cli containerd.io</code>

<code>systemctl start docker
systemctl enable docker</code>

<code>cat > /etc/yum.repos.d/kubernetes.repo <<EOF
[kubernetes]

<code>yum install -y kubelet kubeadm kubectl
systemctl enable kubelet
systemctl start kubelet</code>

<code>kubeadm init --apiserver-advertise-address <master-ip> --image-repository registry.aliyuncs.com/google_containers --kubernetes-version <version> --service-cidr <service-cidr> --pod-network-cidr <pod-network-cidr></code>

<code>kubectl apply -f https://docs.projectcalico.org/manifests/calico.yaml</code>

<code>kubectl get nodes</code>
