基于cygwin的Hadoop Windows环境搭建

杏儿9801

　　在装完cygwin后我们一般将它添加到win7系统环境变量PATH中：
　　D:\cygwin\bin;D:\cygwin\usr\sbin;
　　
　　在cygwin中开启停用删除服务的命令：
　　开启服务: $ net start 服务名
　　停止服务: $ net stop 服务名
　　删除服务: $ cygrunsrv -R 服务名
　　
　　cygwin自带的命令：
　　检查所有安装的软件的版本号: $ cygcheck -c
检查当前Cygwin的版本号: $ cygcheck -c cygwin
　　
　　cygwin编译搭建hadoop环境需要安装的软件包：
　　1.openssh
2.openssl
3.sed
4.zlib
4.tcp_wrappers
5.diffutils
6.vim
7.subversion
　　8.mpfr（版本4）
　　
　　cygwin没有自动卸载功能，需要手动操作3个步骤如下：
　　1.停止服务: $ net stop 服务名
　　2.删除服务: $ cygrunsrv -R 服务名
　　3.删除cygwin文件
　　
　　然后如下进行操作(因为是重新安装，与第一次安装稍有区别)
