NameNodeResourceManagerDFSZKFC：DFS Zookeeper Failover Controller 激活Standby NameNodeDataNodeNodeManagerJournalNode：NameNode共享editlog结点服务（如果使用NFS共享，则该进程和所有启动相关配置接可省略）。QuorumPeerMain：Zookeeper主进程
目录规划：
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/hosts192.168.254.151 Hadoop-NN-01192.168.254.152 Hadoop-NN-02192.168.254.153 Hadoop-DN-01 Zookeeper-01192.168.254.154 Hadoop-DN-02 Zookeeper-02192.168.254.155 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.shexport 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 cdh5export HADOOP_HOME=/home/hadoopuser/hadoop-2.6.0-cdh5.6.0export 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：/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
（1）修改$HADOOP_HOME/etc/hadoop/hadoop-env.sh
#--------------------Java Env------------------------------export JAVA_HOME="/usr/java/jdk1.8.0_73"#--------------------Hadoop Env----------------------------#export HADOOP_PID_DIR=${HADOOP_PID_DIR}export HADOOP_PREFIX="/home/hadoopuser/hadoop-2.6.0-cdh5.6.0"#--------------------Hadoop Daemon Options-----------------# export HADOOP_NAMENODE_OPTS="-Dhadoop.security.logger=${HADOOP_SECURITY_LOGGER:-INFO,RFAS} -Dhdfs.audit.logger=${HDFS_AUDIT_LOGGER:-INFO,NullAppender} $HADOOP_NAMENODE_OPTS"# export HADOOP_DATANODE_OPTS="-Dhadoop.security.logger=ERROR,RFAS $HADOOP_DATANODE_OPTS"#--------------------Hadoop Logs---------------------------#export HADOOP_LOG_DIR=${HADOOP_LOG_DIR}/$USER#--------------------SSH PORT-------------------------------export HADOOP_SSH_OPTS="-p 6000" #如果你修改了SSH登录端口，一定要修改此配置。
（2）修改$HADOOP_HOME/etc/hadoop/core-site.xml

（4）修改 $HADOOP_HOME/etc/hadoop/yarn-env.sh
#Yarn Daemon Options#export YARN_RESOURCEMANAGER_OPTS#export YARN_NODEMANAGER_OPTS#export YARN_PROXYSERVER_OPTS#export HADOOP_JOB_HISTORYSERVER_OPTS#Yarn Logsexport YARN_LOG_DIR="/home/hadoopuser/hadoop-2.6.0-cdh5.6.0/logs"
（5）修改$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：

（7）修改$HADOOP_HOME/etc/hadoop/slaves
Hadoop-DN-01Hadoop-DN-02Hadoop-DN-03
3、分发程序
#因为我的SSH登录修改了端口，所以使用了 -P 6000scp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-NN-02:/home/hadoopuserscp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-DN-01:/home/hadoopuserscp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-DN-02:/home/hadoopuserscp -P 6000 -r /home/hadoopuser/hadoop-2.6.0-cdh5.6.0 hadoopuser@Hadoop-DN-03:/home/hadoopuser
4、启动HDFS
（1）启动JournalNode：
[hadoopuser@Linux01 hadoop-2.6.0-cdh5.6.0]$ 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]$ jps5652 QuorumPeerMain9076 Jps9029 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
