Linux SSH命令错误：ECDSA host key "ip地址" for has changed and you have requested strict checking.记录下方便记忆。
解决方案：在终端上输入以下命令：
ssh-keygen -R "你的远程服务器ip地址"
目的是清除你当前机器里关于你的远程服务器的缓存和公钥信息，注意是大写的字母“R”。
原因分析：根据个人的情况，原因是我的云服务器重装了系统（清除了与我本地SSH连接协议相关信息），本地的SSH信息便失效了，使用SSH连接相同的ip地址时使用的是失效的协议信息，所以会报错，使用上述命令便可以清除known_hosts里旧缓存文件
