在 Linux 上以 All-in-One 模式安装 KubeSphere

一、下载 KubeKey

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

如果下载不下来，可以直接通过连接下载：

wget https://github.com/kubesphere/kubekey/releases/download/v1.1.1/kubekey-v1.1.1-linux-amd64.tar.gz

为 kk 添加可执行权限：

chmod +x kk

二、开始安装

若要同时安装 Kubernetes 和 KubeSphere，可参考以下示例命令：

# export KKZONE=cn # 该命令一定要执行，否则相关的包和镜像拉不下来
./kk create cluster --with-kubernetes v1.20.4 --with-kubesphere v3.1.1

在安装的时候，报了如下错误：

[root@centos03 kubesphere]# chmod +x kk
[root@centos03 kubesphere]# ls -l
总用量 13348
-rwxr-xr-x. 1 root root 13668116 10月  9 19:02 kk
[root@centos03 kubesphere]# ./kk create cluster --with-kubernetes v1.20.4 --with-kubesphere v3.1.1

centos03: conntrack is required. 

安装工具：

> yum install conntrack-tools

然后重新执行上边的命令：

又报了如下错误：

处理器核数至少为2核，所以，需要分配更大的核数(2)和内存(4G)。

修改完虚拟机核数和内存后，继续执行上边的命令：
