通过AWS CLI自动替换EC2实例IP地址
背景
平时在AWS EC2上跑了点东西，方便查学习资料（你懂的）。之所以选择AWS是因为它家提供1年免费套餐，另外海外节点稳定。起先一切看起来不错，可以实现自由冲浪。
但过不了多久就会被 王府井 屏蔽，没办法，多启几个容器吧（内存有限，一次启用5个不同的端口，发现不好用时手工切换本机客户端端口呗，5个端口都换完了就重新绑定个弹性IP，也算个解决办法。
但最近发现， 王府井 的效率变高了。基本上只要访问过一次受限网站，过不了几分钟这个端口就被封了，这让我怎么学习？没办法，不得不重新更换一个新的弹性IP地址。更换IP地址的过程是这样的：
- 登录AWS控制台（国内访问速度比较慢）
- 切换到EC2控制面板
- 分配新的弹性IP地址
- 将新地址绑定到EC2实例
- 释放旧的IP地址
一轮操作下来，一般要十几分钟。有时候半天登录不上，痛苦啊啊啊。。。
每次重复劳动，对于我这个希望用行动改变世界的码农来说，不是我性格啊。趁今天有空，研究了一下如何用AWS命令行工具（AWS CLI）自动替换EC2实例的弹性IP地址，节省我的时间。
