win7下搭建hadoop2.6.0伪分布式平台
来源:互联网 发布:文化部网络直播黑名单 编辑:程序博客网 时间:2024/06/05 04:53
准备事项:
win7下安装VMware,Ubuntu
由于hadoop仅在linux系统作为生产平台
安装JDK1.7
1.打开终端,建立新目录:/usr/local/java,即执行命令:sudo mkdir /usr/local/java
2.将下载好的JDK放入/usr/local/java目录下,进入/usr/local/java目录,解压缩JDK,执行命令:sudo tar -zxvf jdk-7u75-linux-i586.gz
3.配置JDK环境变量,编辑 vim ~/.bashrc
添加:
export JAVA_HOME=/usr/local/java/jdk1.7.0_75export PATH=${JAVA_HOME}/bin:$PATH执行命令:source ~/.bashrc 让配置立即生效
4.验证,执行javac命令
安装SSH,并配置SSH免密码登陆
1.安装ssh,执行命令:sudo apt-get install ssh
2.启动ssh服务,执行命令:sudo /etc/init.d/ssh start
3.设置免密码登录,执行命令:ssh-keygen -t rsa 一路回车下去,最后在/home/hadoop/.ssh下生产id_rsa和id_rsa.pub文件,进入/home/hadoop/.ssh目录下,执行命令:cat id_rsa.pub >> authorized_keys
4.至此,免密码登录设置完成,验证是否能免密码登录,执行命令:ssh localhost
安装hadoop
1.建立安装目录:/usr/local/hadoop
2.将下载的hadoop2.6.0安装包放入此目录下,解压缩
3.编辑~/.bashrc,即执行命令:vim ~/.bashrc
添加内容:
export HADOOP_HOME=/usr/local/hadoop/hadoop-2.6.0export PATH=$HADOOP_HOME/bin:$PATH
编辑vim /etc/hosts
修改内容:
127.0.0.1 localhost#127.0.1.1 master192.168.213.128 master# The following lines are desirable for IPv6 capable hosts::1 ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters
4.修改配置文件hadoop-env.sh
添加内容:
export JAVA_HOME=/usr/local/java/jdk1.7.0_75export HADOOP_HOME=/usr/local/hadoop/hadoop-2.6.0export PATH=$PATH:$HADOOP_HOME/bin
5.修改配置文件core-site.xml

6.修改配置文件hdfs-site.xml

内容为:master
至此,配置完毕,格式化文件系统,执行命令:hadoop namenode -format
9.启动hadoop,执行命令:./start-all.sh
