安装Hadoop

1.创建hadoop目录，并将hadoop-1.2.1-bin.tar.gz 拷贝到目录下

[root@localhost root]# cd /opt/software[root@localhost software]# lshadoop-1.2.1-bin.tar.gz  jdk-6u45-linux-i586.bin  jvm[root@localhost software]# mkdir hadoop[root@localhost software]# lshadoop  hadoop-1.2.1-bin.tar.gz  jdk-6u45-linux-i586.bin  jvm[root@localhost software]# cp hadoop-1.2.1-bin.tar.gz /opt/software/hadoop[root@localhost software]# cd hadoop[root@localhost hadoop]# lshadoop-1.2.1-bin.tar.gz

2.解压hadoop文件

[root@localhost hadoop]# tar -zxvf hadoop-1.2.1-bin.tar.gz

3.配置环境变量

vi /etc/profile添加以下内容

export HADOOP_HOME=/opt/software/hadoop/hadoop-1.2.1export PATH=$PATH:/opt/software/hadoop/hadoop-1.2.1/bin

4.测试

[root@localhost root]# source /etc/profile[root@localhost root]# hadoop

5.配置JAVA_HOME

[root@localhost root]# cd /opt/software/hadoop
[root@localhost hadoop]# ls
hadoop-1.2.1 hadoop-1.2.1-bin.tar.gz
[root@localhost hadoop]# cd hadoop-1.2.1
[root@localhost hadoop-1.2.1]# ls

[root@localhost conf]# more hadoop-env.sh
