第一步:安装JDK
略。
第二步:安装Cygwin
官方网址:http://www.cygwin.com/ 下载setup.exe
安装时选择相应的安装包:
Base-->sed
Editors-->vim
Libs-->
Net-->OpenSSH
第三步:配置Windows系统变量
jdk安装:
JAVA_HOME=E:\Program Files\Java\jdk1.6.0_22
path中添加 jdk,jre:
%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;
path中添加cygwin bin路径:
E:\Program Files\cygwin\bin;E:\Program Files\cygwin\usr\sbin;
环境变量中-->新建变量-->CYGWIN-->对应的值为:ntsec tty
第四步:安装并配置sshd服务
键入命令:
ssh-host-config
本人第一次配置的时候没有成功,然后又卸载Cgywin(卸载cygwin,也不是一件容易的事情),卸载sshd服务,网上有的方法几乎都试过,总算迷迷糊糊就给设置好了。
可参考一下文章:http://pwcrab.blog.163.com/blog/static/16990382220107267443810/ (Cygwin上安装、启动ssh服务失败、ssh localhost失败的解决方案)

注意:在安装ssh服务的时候仔细阅读,cygwin上的Info信息。
*** Info: On Windows Server 2003, Windows Vista, and above, the
*** Info: SYSTEM account cannot setuid to other users -- a capability
*** Info: sshd requires. You need to have or to create a privileged
*** Info: account. This script will help you do so.
*** Info: You appear to be running Windows XP 64bit, Windows 2003 Server,
*** Info: or later. On these systems, it's not possible to use the LocalSystem
*** Info: account for services that can change the user id without an
*** Info: explicit password (such as passwordless logins [e.g. public key
*** Info: authentication] via sshd).
*** Info: If you want to enable that functionality, it's required to create

*** Info: Note that creating a new user requires that the current account

win7下安装ssh服务,不是一路顺风的。
我的win7安装ssh服务后的变化如下:
具体什么原因,我也不是很清楚。
最后记得,测试你的ssh服务是否安装成功。
第五步:配置Hadoop安装包
下载Hadoop安装包
修改配置文件:
hadoop-env.sh
export JAVA_HOME=/cygdrive/E/Progra~1/Java/jdk1.6.0_22
注意:Program Files改为Progra~1 否则 启动Hadoop的时候会报错。
core-site.xml
fs.default.name
hdfs://localhost:9000
hdfs-site.xml
dfs.replication
1
mapred-site.xml
mapred.job.tracker
localhost:9001
启动Hadoop
格式化HDFS文件系统:(执行此命令,必须进入hadoop的bin目录,而且hadoop的路径不能有空格,所以建议将hadoop安装在根目录)
启动Hadoop守护进程:
验证Hadoop是否启动:
历经千辛万苦,多少个不眠的日夜,多少人都劝我还是去Linux下,也曾经想放弃了,终于还是凭着坚强毅力,成功了。当然,这仅仅是第一步。 |
