1.单节点部署

1.1 开通服务器

hostnamectl set-hostname node1

1.2 开通服务器

1.2.3 准备KubeKey

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

1.2.2 使用KubeKey引导安装集群

#可能需要下面命令
yum install -y conntrack

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

1.2.3 安装后开启功能

2.多节点部署

2.1 准备三台服务器

• 4c8g （master）
• 8c16g * 2（worker）
• centos7.9
• 内网互通
• 每个机器有自己域名
• 防火墙开放30000~32767端口

2.2 准备三台服务器

2.2 开通服务器

2.2.1 准备KubeKey

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

2.2.2 创建集群配置文件

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

2.2.3 创建集群

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

2.2.4 查看进度

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
