概述
其实有时候安装搭建这个东西是费时费力的事情，如果有脚本为什么不能使用脚本呢？花100分钟在搭建上还不如用100分钟去研究怎么使用
什么是kubekit
Kubekit是一个部署工具包，它为kubernetes提供离线安装解决方案。您可以使用它将Kubernetes部署到OFFLINE生产环境。
Kubekit将安装
- Docker（1.12.6）
- Kubernetes及其所有组件
- Kubernetes仪表板，默认节点端口：31234
kubkit地址
https://github.com/Orientsoft/kubekit
操作系统
首先官方支持下面两个操作系统，而且都要是最小化安装支持的
- CentOS release 7.3.1611
- CentOS release 7.4.1708
我使用是1708，k8s版本是V1.9.2，具体的可以看github上的readme
wget http://111.1.50.85/files/1128000004BF9EC9/linux.cc.lehigh.edu/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1708.iso
在虚拟机里面正常安装，注意是最小化安装，我给虚拟机的内存是2g，希望有一天我也可以买台mac book pro吧
安装完成之后关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
关闭selinux
setenforce 0
vim /etc/selinux/config
修改为
SELINUX=disabled
最好还可以同步一下时间什么的
yum install ntpdate
ntpdate 0.cn.pool.ntp.org
下载kubekit
yum install wget
wget https://kubekit.orientsoft.cn/kubekit-linux64-0.3.tar.gz
解压
tar -zxvf kubekit-linux64-0.3.tar.gz
mv kubekit-release/ kubekit
下载离线包并且安装集群
wget https://kubekit.orientsoft.cn/package-1.9.2.tar.gz
tar -zxvf package-1.9.2.tar.gz
mv package kubekit
给脚本赋予可执行权限
cd kubekit/package/
chmod +x ./*.sh
最后安装并初始化master节点
./kubekit init 192.168.38.166
到下面这步就说明节点初始化成功了
[root@kubekit kubekit]# ./kubekit init 192.168.38.166

接着ctrl+c退出来，然后重新启动kubekit的dashboard并且放在后台
./kubekit server &
添加一个node
浏览器访问ip:9000
创建一个同样安装着centos 1708最小化安装的机器，之后打开修改主机名
hostnamectl set-hostname kubekit-node1
接着点击web界面上的add node，输入ssh账号密码等信息，最后选中点击start deploy就可以了
之后你就会在kubernetes的dashboard看到这个节点的详细信息了
