Cygwin是一个在windows平台上运行的类UNIX模拟环境，它对于学习UNIX/Linux操作环境，或者从UNIX到Windows的应用程序移植，或者进行某些特殊的开发工作，尤其是使用GNU工具集在Windows上进行嵌入式系统开发，非常有用。
因为要学习hadoop分布式文件系统，想在window下模拟linux环境进行部署。所以想到用cygwin工具。
1.安装时最好明确自己要安装那些服务，根据自己的实际需要而定，我一次安装就因为漏选了openssh，后来重装了，
2.重装可以不用先卸载，直接点击setup.exe,进行安装，
3.那个选择下载站点就选默认的就好了http://mirrons.163.com。
4.安装ssh服务时配置无密码是总是出错
错误如下：删掉.ssh文件夹，用密码登陆也是不成功。试了好几次，也重装了cygwin64位还是无效，最后安装cygwin32位的才可以。

网上安装教材很多，我就不赘述了。
