hadoop安装 伪分布

伪分布hadoop 安装总结

准备，在配置中hadoop用的9000端口，如果有其它软件用着这个端口，建议更换后再进行下面配置，以避免出现错误。比如php-fpm经常使用9000端口。

一、下载jdk
下载linux 64 8u73-64位版本
tar zxvf jdk-8u74-linux-x64.tar.gz -C /usr/local/

二、下载hadoop
tar zxvf hadoop-2.6.4.tar.gz -C /usr/local/

配置项:

vim /etc/profile.d/hadoop.sh
export JAVA_HOME=/usr/local/jdk1.8.0_74
export JRE_HOME=/usr/local/jdk1.8.0_74/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
export HADOOP_HOME=/usr/local/hadoop-2.6.4
export HADOOP_PREPATH=/usr/local/hadoop-2.6.4
export HADOOP_PID_DIR=/usr/local/hadoop-2.6.4/pid
export YARN_PID_DIR=/usr/local/hadoop-2.6.4/pid
export HADOOP_MAPRED_PID_DIR=/usr/local/hadoop-2.6.4/pid
export PATH=$HADOOP_HOME/bin:$PATH
