遇到问题解决 写文备忘

1.安装相关环境

curl -fsSL https://get.docker.com | bash
systemctl start docker 
systemctl enable docker
yum install -y socat conntrack ebtables ipset iproute-tc   

如果docker安装报错

执行

yum erase podman buildah

2.下载KK

export KKZONE=cn
curl   -fL https://get-kk.kubesphere.io | VERSION=v3.0.13 sh -

国内网络 只能curl -x 通过代理了

export KKZONE=cn
curl -x socks5://192.168.0.248:7890  -fL https://get-kk.kubesphere.io | VERSION=v3.0.13 sh -

3.设置主机名

我准备了三台虚拟机 node1 node2 node3
注意虚拟机核心数需要大于2
否则后面报 [ERROR NumCPU]: the number of available CPUs 1 is less than the required 2

hostnamectl set-hostname node1

/etc/hosts修改

192.168.0.121  node1
192.168.0.122  node2
192.168.0.123  node3

3.同时安装 Kubernetes 和 KubeSphere

自己选的v1.23.17 官方教程说1.23以上版本可能边缘节点不可用

3.1 创建配置文件

./kk create config  --with-kubernetes v1.23.17 --with-kubesphere v3.4.1 [-f ~/config-sample.yaml]

如果要装kubesphere企业版先单纯安装k8s

./kk create config  --with-kubernetes v1.23.17 [-f ~/config-sample.yaml]

然后参考https://docs.kubesphere.com.cn/v4.0/03-install-and-uninstall/01-install-ks-core/ 安装

3.2 编辑配置文件

vi config-sample.yaml编辑节点

apiVersion: kubekey.kubesphere.io/v1alpha2
kind: Cluster
metadata:
  name: sample
spec:
  hosts:
  - {name: node1, address: 192.168.0.121, internalAddress: 192.168.0.121, user: root, password: "123456"}
  - {name: node2, address: 192.168.0.122, internalAddress: 192.168.0.122, user: root, password: "123456"}
  - {name: node3, address: 192.168.0.123, internalAddress: 192.168.0.123, user: root, password: "123456"}
  roleGroups:
    etcd:
    - node1
    control-plane: 
    - node1
    worker:
    - node1
    - node2
    - node3

注意 默认的配置文件hosts worker 只有两个 记得添加额外的node3

3.3 安装

export KKZONE=cn
./kk create cluster -f config-sample.yaml

成功标志

4. 添加节点

vi config-sample.yaml
hosts worker各再多加一行
添加节点

export KKZONE=cn
./kk add nodes -f config-sample.yaml
