集群安装：
一、关闭防火墙（防火墙可以以后配置）
二、安装JDK（略）
三、修改HostName并配置Host（5台）
[root@Linux01 ~]# vim /etc/sysconfig/network [root@Linux01 ~]# vim /etc/hosts 192.168.254.151 Hadoop-NN-01 192.168.254.152 Hadoop-NN-02 192.168.254.153 Hadoop-DN-01 Zookeeper-01 192.168.254.154 Hadoop-DN-02 Zookeeper-02 192.168.254.155 Hadoop-DN-03 Zookeeper-03
四、为了安全，创建Hadoop专门登录的用户（5台）
[root@Linux01 ~]# useradd hadoopuser [root@Linux01 ~]# passwd hadoopuser [root@Linux01 ~]# su – hadoopuser #切换用户
五、配置SSH免密码登录（2台NameNode）
[hadoopuser@Linux05 hadoop-2.6.0-cdh5.6.0]$ ssh-keygen --生成公私钥
[hadoopuser@Linux05 hadoop-2.6.0-cdh5.6.0]$ ssh-copy-id -i ~/.ssh/id_rsa.pub hadoopuser@Hadoop-NN-01
-I 表示 input
~/.ssh/id_rsa.pub 表示哪个公钥组
或者省略为：
[hadoopuser@Linux05 hadoop-2.6.0-cdh5.6.0]$ ssh-copy-id Hadoop-NN-01（或写IP：10.10.51.231） #将公钥扔到对方服务器 [hadoopuser@Linux05 hadoop-2.6.0-cdh5.6.0]$ ssh-copy-id ”-p 6000 Hadoop-NN-01” #如果带端口则这样写
注意修改Hadoop的配置文件
vi Hadoop-env.sh export HADOOP_SSH_OPTS=”-p 6000” [hadoopuser@Linux05 hadoop-2.6.0-cdh5.6.0]$ ssh Hadoop-NN-01 #验证（退出当前连接命令：exit、logout） [hadoopuser@Linux05 hadoop-2.6.0-cdh5.6.0]$ ssh Hadoop-NN-01 –p 6000 #如果带端口这样写
六、配置环境变量：vi ~/.bashrc 然后 source ~/.bashrc（5台）
[hadoopuser@Linux01 ~]$ vi ~/.bashrc # hadoop cdh5 export HADOOP_HOME=/home/hadoopuser/hadoop-2.6.0-cdh5.6.0 export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin [hadoopuser@Linux01 ~]$ source ~/.bashrc #生效
七、安装zookeeper（3台DataNode）
安装文档：http://www.cnblogs.com/hunttown/p/5807383.html
八、安装Hadoop，并配置（只装1台配置完成后分发给其它节点）
1、解压
2、修改配置文件

（5）修改 $HADOOP_HOEM/etc/hadoop/mapred-site.xml
<configuration> <!-- 配置JVM大小 --> <property> <name>mapred.child.java.opts</name> <value>-Xmx1000m</value> <final>true</final> <description>final=true表示禁止用户修改JVM大小</description> </property> <!-- 配置 MapReduce Applications --> <property> <name>mapreduce.framework.name</name> <value>yarn</value> </property> <!-- JobHistory Server ============================================================== --> <!-- 配置 MapReduce JobHistory Server 地址 ，默认端口10020 --> <property> <name>mapreduce.jobhistory.address</name> <value>0.0.0.0:10020</value> </property> <!-- 配置 MapReduce JobHistory Server web ui 地址， 默认端口19888 --> <property> <name>mapreduce.jobhistory.webapp.address</name> <value>0.0.0.0:19888</value> </property> </configuration>
HBase的配置：
<!-- HBase使用 start --> <property> <name>mapred.remote.os</name> <value>Linux</value> </property> <property> <name>mapreduce.app-submission.cross-platform</name> <value>true</value> </property> <property> <name>mapreduce.application.classpath</name> <value> /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/etc/hadoop, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/common/*, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/common/lib/*, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/hdfs/*, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/hdfs/lib/*, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/mapreduce/*, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/mapreduce/lib/*, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/yarn/*, /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/share/hadoop/yarn/lib/*, /usr/local/hbase/lib/* </value> </property> <!-- HBase使用 end -->
另：JVM配置也可以这么写：
<property> <name>mapred.task.java.opts</name> <value>-Xmx2000m</value> </property> <property> <name>mapred.child.java.opts</name> <value>${mapred.task.java.opts} -Xmx1000m</value> <final>true</final> <description>相同的jvm arg写在一起，比如"-Xmx2000m -Xmx1000m"，后面的会覆盖前面的，也就是说最终“-Xmx1000m”才会生效。</description> </property>
另：如果要分别配置map和reduce的JVM大小，可以这么写

（7）修改 $HADOOP_HOME/etc/hadoop/slaves
Hadoop-DN-01 Hadoop-DN-02 Hadoop-DN-03
3、分发程序
#因为我的SSH登录修改了端口，所以使用了 -P 6000 scp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-NN-02:/home/hadoopuser scp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-DN-01:/home/hadoopuser scp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-DN-02:/home/hadoopuser scp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-DN-03:/home/hadoopuser
4、启动HDFS
（1）启动JournalNode：
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ hadoop-daemon.sh start journalnode starting journalnode, logging to /home/hadoopuser/hadoop-2.6.0-cdh5.6.0/logs/hadoop-puppet-journalnode-BigData-03.out
验证JournalNode：
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ jps 5652 QuorumPeerMain 9076 Jps 9029 JournalNode
停止JournalNode：
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ hadoop-daemon.sh stop journalnode stoping journalnode
（2）NameNode 格式化：
结点Hadoop-NN-01：hdfs namenode -format
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ hdfs namenode -format
（3）同步NameNode元数据：
同步Hadoop-NN-01元数据到Hadoop-NN-02
主要是：dfs.namenode.name.dir，dfs.namenode.edits.dir还应该确保共享存储目录下(dfs.namenode.shared.edits.dir ) 包含NameNode 所有的元数据。
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ scp -P 6000 -r data/ hadoopuser@Hadoop-NN-02:/home/hadoopuser/hadoop-2.6.0-cdh5.6.0
（4）初始化ZFCK：
创建ZNode，记录状态信息。
结点Hadoop-NN-01：hdfs zkfc -formatZK
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ hdfs zkfc -formatZK
（5）启动
集群启动法：Hadoop-NN-01： start-dfs.sh
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ start-dfs.sh
单进程启动法：

（7）停止：stop-dfs.sh
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ stop-dfs.sh
5、启动Yarn
（1）启动
