2CPU 8核16线程
48G 内存
380G硬盘
1.配置Hadoop的全局环境变量
输入名称# vi /etc/profile打开profile文件，按i可以进入文本输入模式，在profile文件的最后增加HADOOP_HOME及修改PATH的环境变量，输入:wq！保存退出。
export HADOOP_HOME=/usr/local/hadoop-2.6.0
export PATH=.:$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$SCALA_HOME/bin
2.在命令行中输入source /etc/profile，使刚才修改的HADOOP_HOME及PATH配置文件生效。
3.hadoop-env.sh配置文件修改
export JAVA_HOME=/usr/local/jdk1.8.0_60
4.core-site.xml核心配置文件修改
<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>/usr/local/hadoop-2.6.0/tmp</value>
<description>hadoop.tmp.dir</description>
</property>
<property>
<name>fs.defaultFS</name>
<value>hdfs://master:9000</value>
</property>
</configuration> 5.hdfs-site.xml配置文件修改
<configuration>
<property>
<name>dfs.replication</name>
<value>3</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>/usr/local/hadoop-2.6.0/tmp/dfs/name</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value> /usr/local/hadoop-2.6.0/tmp/dfs/data</value>
</property>
</configuration> 6.salves 修改

7。分发hadoop
root@master:/usr/local# cd setup_scripts
root@master:/usr/local/setup_scripts# ls
host_scp.sh ssh_config.sh ssh_scp.sh
root@master:/usr/local/setup_scripts#
root@master:/usr/local/setup_scripts# cat hadoop_scp.sh
#!/bin/sh
for i in 2 3 4 5 6 7 8 9
do
scp -rq /etc/profile root@192.168.189.$i:/etc/profile
ssh root@192.168.189.$i source /etc/profile
scp -rq /usr/local/hadoop-2.6.0 root@192.168.189.$i:/usr/local/hadoop-2.6.0
done
root@master:/usr/local/setup_scripts#
8。执行完成
9。格式化hdfs namenode -format
root@master:/usr/local/setup_scripts# cd /usr/local/hadoop-2.6.0/bin
root@master:/usr/local/hadoop-2.6.0/bin# hdfs namenode -format
10。启动集群
root@master:/usr/local/hadoop-2.6.0/sbin# start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
