### 重点集群配置推荐,太低会导致安装异常
**

- - node节点最低4gb
- - Master节点最低8gb**

* Q群名称：K8s自动化部署交流
* Q群   号：893480182
### - 实测单机版支持腾讯云服务器
### - 实测集群版支持天翼云服务器
### - 实测集群版支持阿里云服务器(需要预先设置中文字符集否则菜单界面乱码不显示中文，后续我会修复这个问题到脚本里面 暂时没有阿里云服务器调试)

特点: 完全离线，不依赖互联网(系统新装配置好ip开机即可！其他都什么都不用安装)
====
1. 真正原生centos7.3.-7.6Minimal新装系统(只需要统一集群的root密码即可)一键搭建k8s集群
1. 单机/集群任意服务器数量一键安装(目前一个节点对应一个etcd节点后续会分离可自定义)
1. 一键批量增删node节点(新增的服务器系统环境必须干净密码统一)
1. ipvs负载均衡,内网yum源共享页面端口42344
1. 单机版或集群版默认集成prometheus+grafan监控环境,默认端口30000,账号密码admin admin
1. 图形化向导菜单安装,web管理页面dashboar端口42345
1. Heketi+GlusterFS（分布式存储集群）+helm完全一键离线部署
1. 默认版本v1.15.7,可执行替换各版本软件包,集群版目前已测安装数量在1-30台一键安装正常
1. 集群数量超过4台及以上默认开启k8s数据持久化方案:glusterfs+Heketi 最低3台分布式存储 \n (全自动自动安装,启用k8s集群持久化方案务必保证存储节点均有一块空盘(例如/deb/sdb无需分区(默认40%用于k8s集群持久化60%挂载到本机的/data目录)))
如启用Heketi+GlusterFS，默认会创建一个pvc验证动态存储效果

一键安装
===
#### 一键安装介绍任选通道进行安装
一键安装命令(要求centos7系统为新装系统无任何软件环境可联网)
不推荐git下来仓库大概1.5gb左右比较大，可以直接下载离线包
##一键安装通道01(默认走家庭宽带普通通道---不稳定不推荐)
``` shell
while [ true ]; do  rm -f K8s_1.2.tar*;curl  -o   K8s_1.2.tar  http://www.linuxtools.cn:42344/K8s_1.2.tar && break 1 ||sleep 5;echo 网络错误正在重试下载 ;done && tar -xzvf  K8s_1.2.tar && cd K8s/ && sh install.sh
```

##一键安装通道02(走群友无私赞助电信机房专线服务器--高速稳定下载----强烈推荐)

``` shell
while [ true ]; do  rm -f K8s_1.2.tar*;curl  -o   K8s_1.2.tar  http://www.linuxtools.cn:42344/K8s_1.2.tar && break 1 ||sleep 5;echo 网络错误正在重试下载 ;done && tar -xzvf  K8s_1.2.tar && cd K8s/ && sh install.sh
```

*  ps:近期提交代码过于频繁有时候可能会有=一些bug,欢迎到群随时提出

====
### [高能警告] 系统只能存在一个固定ip地址 一个网卡一个ip 切记美分系统不能多个ip多个网卡
### [高能警告] 暂仅支持centos7.3-centos7.7， “不支持Centos7.2及其以下版本”
### [高能警告] 系统ip不能使用 10.0.0.0网段,尽量避开系统使用172.17.x.x  10.0.0.x网段(否则安装会有问题)

** 
# K8s升级替换v1.14.0   v1.15.0
#如果不需要使用v1.14.0  v1.15.0直接默认一键安装即可。master分支默认的是v1.15.7
## 默认版本为v1.15.7,提供升级软件包v14  v15自行下载后放到  K8s/Software_package  目录即可(务必删除原有的)
链接：[http://linuxtools.cn:42344/K8s_list/](http://linuxtools.cn:42344/K8s_list/)

放入前务必执行以下操作
``` shell
rm -fv  K8s/Software_package/kubernetes-server-linux-amd64.tar.a*
```

``` shell
#可选执行-----替换第三方yum源
rm  -fv  rm -f /etc/yum.repos.d/*

##一键安装通道02(走码云服务器)

``` shell
#零时弃用
```

#### 测试环境
* VMware15虚拟化平台，所有服务器节点2核2G
* 已测1-50节点安装正常
* 建议新装centos7.6系统,环境干净(不需要提前安装任何软件不需要提前安装docker).集群功能至少2台服务器节点

网络  | 系统  | 内核版本 | IP获取方式 | docker版本 | Kubernetes版本 |K8s集群安装方式 |
---- | ----- | ------  | ---- |  ---- | ---- | ---- |
桥接模式  | 新装CentOS7.6.1810 (Core) | 3.10.0-957.el7.x86_64 | 手动设置固定IP(不能dhcp获取所有节点) | 18.06.1-ce | v1.15.7  | 二进制包安装  |

#### 安装教程
``` shell
rm -f K8s_1.2.tar*

#下载通道01 走普通家庭宽带下载点
``` shell
