-# 本脚本提供如下功能，作者：Joey Yang, https://github.com/Code2Life
-# 1. 在Ubuntu/CentOS/Fedora/ArchLinux中自动化的安装python+ansible;
-# 2. clone kubeasz项目代码, 并将需要的二进制文件下载解压到/etc/ansible/bin中;
-# 另外, 相关的k8s二进制文件, 我同步到了个人在七牛上的CDN存储中（速度更快）, 方便大家下载: filecdn.code2life.top;
-# 
-# 使用方法：
-# 1. 支持带参数的运行, 如: ./basic-env-setup.sh k8s.193.tar.gz 指定不同的kubernetes二进制文件, 无参数时默认最新的k8s.1100.tar.gz (k8s 1.10.0 + etcd 3.3.2).
-# 2. 也可以在任何一台支持的linux设备运行：curl http://filecdn.code2life.top/kubeasz-basic-env-setup.sh | sh -s
-# 已经亲测centos7/ubuntu16.04/debian9/fedora27都是可以的, 二进制包下载速度贼快.脚本运行完毕之后, 只需到/etc/ansible目录下配置好hosts, 复制完ssh的公钥即可通过ansible-playbook迅速搭建集群了.

-bin_resource_url='http://filecdn.code2life.top/k8s.1100.tar.gz'

-if [ "$1" ];then

-# 敬告：本脚本仅作测试交流使用，详细操作说明请参阅docs/op/change_ip_allinone.md
-# 此脚本仅用于allinone部署情况下，需要修改host ip地址使用（比如，虚机装完allinone部署，克隆或者复制分享给别人测试使用）
-#
-# ------- 前提 ：一个运行正常的allinone部署在虚机，关机后复制给别人使用，新虚机开机后如果需要修改IP，请执行如下步骤
-# 1. 修改ansible hosts文件：sed -i 's/$OLD_IP/$NEW_IP/g' /etc/ansible/hosts
-# 2. 配置ssh免密码登录：ssh-copy-id $NEW_IP 按提示完成
-# 3. 检查下修改是否成功，并且能够成功执行 ansible all -m ping
-# 4. 运行本脚本 ansible-playbook /etc/ansible/tools/change_ip_aio.yml
