Nutch配置全过程

Nutch配置全过程

安装各软件,并设置环境变量.
    辅助软件1:cygwin的安装见上篇文章,cygwin基础入门,我安装在了e:\cygwin.安装后在桌面有个快截方式.
    辅助软件2:jdk安装在C:\Program Files\Java\jdk1.5.0,所以环境变量设置成为JAVA_HOME=C:\Program Files\Java\jdk1.5.0
    辅助软件3:tomcat安装在e:\tomcat 6.0
    nutch不用安装,是个应用程序,下载后为nutch-0.9.tar.gz,双击桌面上的cygwin快捷方式;执行以下命令:
$ cd D:/Downloads/Soft
$ tar zxvf nutch-1.0.tar.gz
在e盘下面出现nutch-0.9文件夹说明解压成功了.然后环境变量设置为NUTCH_JAVA_HOME=C:\Program Files\Java\jdk1.5.0(也就是说跟JAVA_HOME是相同的).测试nutch是否安装成功,只需要执行以下命令:
$cd D:/Downloads/Soft/nutch-1.0/bin
$sh nutch
出现下面的字样就是安装成功了.
