一、安装 docker

One, install docker

root@hello:~# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
----略----


root@hello:~# docker -v
Docker version 20.10.9, build c2ea9bc
root@hello:~#

二，下载安装 KubeKey

Second, download and install KubeKey

从源代码生成二进制文件

Generate binary files from source code

root@hello:~# git clone https://github.com/kubesphere/kubekey.git
Cloning into 'kubekey'...

root@hello:~# 
root@hello:~# cd kubekey
root@hello:~/kubekey# 
root@hello:~/kubekey# 
root@hello:~/kubekey# ./build.sh -p
----略----

注意：

Notice:

在构建之前，需要先安装 Docker。

如果无法访问 https://proxy.golang.org/，比如在墙内，请执行 build.sh -p。

Before building, you need to install Docker.

If you cannot access https://proxy.golang.org/, such as inside a firewall, please execute build.sh -p.

三、安装所需工具

Three， Tools required for installation

root@hello:~# apt install sudo -y
root@hello:~# apt install curl -y
root@hello:~# apt install openssl -y
root@hello:~# apt install ebtables -y
root@hello:~# apt install socat -y
root@hello:~# apt install ipset -y
root@hello:~# apt install conntrack -y
root@hello:~# apt install nfs-common -y

四、创建集群

Fourth, create a cluster

同时安装 Kubernetes 和 KubeSphere

Install Kubernetes and KubeSphere at the same time

root@hello:~# export KKZONE=cn
root@hello:~# /root/kubekey/output/kk create cluster --with-kubernetes v1.20.4 --with-kubesphere v3.1.1
+-------+------+------+---------+----------+-------+-------+-----------+---------+------------+-------------+------------------+--------------+
| name  | sudo | curl | openssl | ebtables | socat | ipset | conntrack | docker  | nfs client | ceph client | glusterfs client | time         |
+-------+------+------+---------+----------+-------+-------+-----------+---------+------------+-------------+------------------+--------------+
| hello | y    | y    | y       | y        | y     | y     | y         | 20.10.9 | y          |             |                  | UTC 02:50:57 |
+-------+------+------+---------+----------+-------+-------+-----------+---------+------------+-------------+------------------+--------------+


This is a simple check of your environment.
Before installation, you should ensure that your machines meet all requirements specified at
https://github.com/kubesphere/kubekey#requirements-and-recommendations


Continue this installation? [yes/no]: yes

五、验证安装结果

Five, verify the installation results

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

注意：

Notice:

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 <NodeIP>:30880 访问控制台

The output information will display the IP address and port number of the Web console. The default NodePort is 30880. Now you can use the default account and password (admin/P@88w0rd) to access the console via <NodeIP>:30880
