最少3台机器
centos Linux 内核:官方建议 3.10 以上
uname -r
control 一台 配置 2c 4g
worker 二台 配置 2c 4g
3台设备需要用不同的hostname,需要提前修改
hostnamectl set-hostname <新的主机名>
# 修改后执行一下命令刷新一下
su -
KubeKey 可以将 Kubernetes 和 KubeSphere 一同安装。针对不同的 Kubernetes 版本,需要安装的依赖项可能有所不同。您可以参考以下列表,查看是否需要提前在节点上安装相关的依赖项
如果没有安装 socat和conntrack可以执行以下命令安装, 记住每台机器都要安装必要依赖
yum install -y socat conntrack ebtables ipset
# 如果访问githu受限可以执行以下命令
# export KKZONE=cn
# 然后在下载KubeKey
curl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.13 sh -
为 kk 添加可执行权限
chmod +x kk
./kk create cluster --with-kubernetes v1.22.12 --with-kubesphere v3.4.1
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f
输出信息会显示 Web 控制台的 IP 地址和端口号,默认的 NodePort 是 30880。现在,您可以使用默认的帐户和密码
(admin/P@88w0rd) 通过 :30880 访问控制台

安装完成后界面如下:
./kk create config --from-cluster
执行后文件生产路径会打印出来

./kk add nodes -f /root/sample.yaml
$ kubectl get node
NAME STATUS ROLES AGE VERSION
master1 Ready master,worker 20d v1.17.9
node1 Ready worker 31h v1.17.9
node2 Ready worker 31h v1.17.9
此时UI可看到新加入集群的node
