10.206.0.12	node1
10.206.0.16	node2

初始化安装环境

systemctl stop firewalld systemctl disable firewalld sed -i 's/enforcing/disabled/' /etc/selinux/config sed -ri 's/.*swap.*/#&/' /etc/fstab cat > /etc/sysctl.d/k8s.conf << EOF net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 EOF sysctl --system yum install ntpdate -y ntpdate time.windows.com

安装依赖
更新yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo yum clean all yum makecache yum update -y#查看当前yum源 yum repolist

安装依赖

yum install -y socat yum install -y conntrack

配置阿里镜像加速
设置仓库地址：https://help.aliyun.com/docum...

cat > /etc/docker/daemon.json << EOF { "registry-mirrors": ["https://xxx.mirror.aliyuncs.com"] } EOF

添加阿里源

cat > /etc/yum.repos.d/kubernetes.repo << EOF [kubernetes] name=Kubernetes baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=0 epo_gpgcheck=0 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg EOF

多节点安装
拉取KubeKey

export KKZONE=cncurl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -chmod +x kk

创建配置文件

./kk create config --with-kubernetes v1.20.4 --with-kubesphere v3.1.1

编辑配置文件

apiVersion: kubekey.kubesphere.io/v1alpha1 kind: Cluster metadata: name: sample spec: hosts: - {name: master, address: 10.206.0.17, internalAddress: 10.206.0.17, user: root, password: 123456} - {name: node1, address: 10.206.0.12, internalAddress: 10.206.0.12, user: root, password: 123456} - {name: node2, address: 10.206.0.16, internalAddress: 10.206.0.16, user: root, password: 123456} roleGroups: etcd: - master master: - master worker: - node1 - node2

开始安装

./kk create cluster -f config-sample.yaml
