0. Hadoop源码包下载
http://mirror.bit.edu.cn/apache/hadoop/common
1. 集群环境
Master 172.16.11.97
Slave1 172.16.11.98
Slave2 172.16.11.99
2. 下载安装包
#Master
wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.8.2/hadoop-2.8.2.tar.gz
tar zxvf hadoop-2.8.2.tar.gz
3. 修改Hadoop配置文件
#Master
cd hadoop-2.8.2/etc/hadoop
vim hadoop-env.sh
export JAVA_HOME=/usr/local/src/jdk1.8.0_152
vim yarn-env.sh
export JAVA_HOME=/usr/local/src/jdk1.8.0_152

#创建临时目录和文件目录
mkdir /usr/local/src/hadoop-2.8.2/tmp
mkdir -p /usr/local/src/hadoop-2.8.2/dfs/name
mkdir -p /usr/local/src/hadoop-2.8.2/dfs/data
4. 配置环境变量
#Master、Slave1、Slave2
vim ~/.bashrc
HADOOP_HOME=/usr/local/src/hadoop-2.8.2
export PATH=$PATH:$HADOOP_HOME/bin
#刷新环境变量
source ~/.bashrc
5. 拷贝安装包
#Master
scp -r /usr/local/src/hadoop-2.8.2 root@slave1:/usr/local/src/hadoop-2.8.2
scp -r /usr/local/src/hadoop-2.8.2 root@slave2:/usr/local/src/hadoop-2.8.2
Hadoop2.0环境安装
