本次部署采用官方离线方式,部署一个k8s集群以及它的可视化页面,在阅读本博客前请先准备3台虚拟机或服务器,具体要求如下:

master: 内存4G 处理器:2核 硬盘:50G
node1: 内存4G 处理器:2核 硬盘:50G
node2: 内存4G 处理器:2核 硬盘:50G
这些准备好之后方可进行安装

1. 配置静态ip
   
2. 设置主机名

 #master节点
hostnamectl  set-hostname  master  
#node1节点
hostnamectl  set-hostname  node1 
#node2节点
hostnamectl  set-hostname  node2  

3. 设置域名

[root@master ~]# vim /etc/hosts 
# 添加如下3行 
10.4.3.91 master 
10.4.3.81 node1 
10.4.3.82 node2
# 其他的2个node节点也需要同样操作

4. 关闭防火墙和禁止防火墙开机启动

systemctl stop firewalld
systemctl disable firewalld

5.时间同步

yum install ntpdate -y
ntpdate time.windows.com

6.设置时区

timedatectl set-timezone Asia/Shangha

7.关机重启
8. 然后参照官方文档开始安装

官方文档地址

1. 下载KubeKey

# 获取访问权限
export KKZONE=cn
#开始下载kk
curl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -
#为kk添加执行权限
chmod +x kk

2.创建集群配置文件，他会下载一个config-sample.yaml的文件

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

3.修改config-sample.yaml文件

所选位置都改成自己的.
4. 执行安装

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

5.等待几个小时候就可以了,全程无需操作,如果因网络原因资源下载失败,可以重新执行这个文件,下载过的他就会跳过.可以使用以下命令查看安装进度

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