【环境安装】hadoop2.x 集群安装_综合

0. Hadoop源码包下载

http://mirror.bit.edu.cn/apache/hadoop/common

1. 集群环境

Master xxx.xxx.xxx.xxx

Slave1 xxx.xxx.xxx.xxx

Slave2 xxx.xxx.xxx.xxx

vim /etc/hosts 里追加

2. 下载安装包

#Master

wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.6.5/hadoop-2.6.5.tar.gz

tar zxvf hadoop-2.6.5.tar.gz

2.1关闭系统防火墙及内核防火墙

#Master、Slave1、Slave2

#清空系统防火墙

iptables -F

#保存防火墙配置

service iptables save

# 临时关闭防火墙

service iptables stop

# 永久关闭防火墙

chkconfig iptables off

#临时关闭内核防火墙

setenforce 0

#永久关闭内核防火墙

vim /etc/selinux/config

SELINUX=disabled

3. 修改Hadoop配置文件

#Master

cd hadoop-2.6.5/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

vim slaves

mkdir /usr/local/src/hadoop-2.6.5/tmp

mkdir -p /usr/local/src/hadoop-2.6.5/dfs/name

mkdir -p /usr/local/src/hadoop-2.6.5/dfs/data

4. 配置环境变量

#Master、Slave1、Slave2

vim ~/.bashrc

export HADOOP_HOME=/usr/local/src/hadoop-2.6.5

export PATH=$PATH:$HADOOP_HOME/bin

#刷新环境变量

source ~/.bashrc

5. 拷贝安装包

#Master
