下载离线包

下载 kubernetes 在 centos7 系统上的 1.19.3 离线包

wget http://kainstall.oss-cn-shanghai.aliyuncs.com/1.19.3/centos7.tgz

更多版本的离线包下载地址见： https://github.com/lework/kainstall-offline

下载脚本

wget https://cdn.jsdelivr.net/gh/lework/kainstall/kainstall.sh

初始化集群

将离线包和脚本一起拷贝到集群master节点中的一台机器上。

在集群master节点中的一台机器上执行

首先，需要安装一些基础包

需要注意的是，因为需要在本地解压离线包和处理数据，需要在线安装一些基础包

yum install -y wget tar sshpass openssh

接着，更新集群节点内核

bash kainstall.sh init \
  --master 192.168.77.130,192.168.77.131,192.168.77.132 \
  --worker 192.168.77.133,192.168.77.134 \
  --user root \
  --password 123456 \
  --port 22 \
  --version 1.19.3 \
  --upgrade-kernel \
  --offline-file centos7.tgz

这里，我们指定了–upgrade-kernel 来先更新内核，不需要的可以去掉。–offline-file 来指定离线包

因为添加了--upgrade-kernel 更新系统内核，所以在内核更新后，需要重启系统应用新内核。

等待集群重启完成后，进入系统查看内核

# uname -a

然后，根据日志提示命令，重新执行脚本进行集群初始化。

通过网页访问dashboard，并输入提供的token

注意： 这里需要绑定下主机名解析,将下面的内容放入到hosts文件中

192.168.77.133 kubernetes-dashboard.cluster.local

kainstall-dashboard

添加节点

在任意 master 节点上操作

首先，更新内核

bash kainstall.sh add \
  --master 192.168.77.135 \
  --worker 192.168.77.136 \
  --user root \
  --password 123456 \
  --port 22 \
  --version 1.19.3 \
  --upgrade-kernel \
  --offline-file centos7.tgz

master 和 worker 节点可同时添加, 也可以分开

其他操作

注意： 添加组件时请保持节点的内存和cpu至少为2C4G的空闲。否则会导致节点下线且服务器卡死。

离线包中不包含以下软件，以下镜像还需自行下载。

# 添加 traefik ingress
bash kainstall.sh add --ingress traefik

# 添加 elasticsearch
bash kainstall.sh add --log elasticsearch

# 添加 rook
bash kainstall.sh add --storage rook

# 添加 prometheus
kainstall.sh add --monitor prometheus

# 更新证书
kainstall.sh renew-cert

# 更新集群版本
kainstall.sh upgrade --version 1.19.3
 

最后

是不是很简单，你只需要准备好服务器，操作下脚本就行了，敲一条命令，喝杯咖啡摸摸鱼，集群就好了。这生活岂不美哉，自动化的魅力！。
