#添加google repo源,要翻牆。
cat <<EOF > /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64 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=kube* EOF #關閉selinux setenforce 0 sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config systemctl enable --now kubelet
二、安裝kubelt kubeadm kubectl
yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes
三、啟動
systemctl enable --now kubelet
其他
#如果防火牆啟動的話,可能需要開啟下面:
cat <<EOF > /etc/sysctl.d/k8s.conf net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 EOF sysctl --system
