安装部署hadoop

(1)安装hadoop

  • master1、master2、slave1、slave2、slave3

#cd /opt/ 
#tar xf  hadoop-2.3.0-cdh6.1.0.tar.gz
#ln -s ln -s  hadoop-2.3.0-cdh6.1.0 hadoop

(2)添加hadoop环境变量

  • master1、master2、slave1、slave2、slave3

#cat >> /etc/profile <

(3)配置hadoop

主要配置文件

(hadoop-2.3.0-cdh6.1.0 /etc/hadoop/)

格式作用
hadoop-env.shbash脚本hadoop需要的环境变量
core-site.xmlxmlhadoop的core的配置项
hdfs-site.xmlxmlhdfs的守护进程配置,包括namenode、datanode
slaves纯文本datanode的节点列表(每行一个)
mapred-env.shbash脚本mapreduce需要的环境变量
mapre-site.xmlxmlmapreduce的守护进程配置
yarn-env.shbash脚本yarn需要的环境变量
yarn-site.xmlxmlyarn的配置项

8:配置slaves

cat >> slaves <

配置完毕



启动集群

(1)格式化命名空间

  • master1

#/opt/hadoop/bin/hdfs zkfc -formatZK

(2)启动journalnode

  • master1、master2、slave1、slave2、slave3 (集群内随意算则奇数台机器作为journalnode,三台也可以)

#/opt/hadoop/sbin/hadoop-daemon.sh start journalnode

(3)master1节点格式化,并启动namenode

  • master1

格式化namenode的目录

#/opt/hadoop/bin/hadoop namenode -format mycluster

启动namenode

#/opt/hadoop/sbin/hadoop-daemon.sh start namenode


(4)master2节点同步master1的格式化目录,并启动namenode

  • master2

从master1将格式化的目录同步过来

#/opt/hadoop/bin/hdfs namenode -bootstrapStandby

启动namenode

#/opt/hadoop/sbin/hadoop-daemon.sh start namenode


(5)master节点启动zkfs

  • master1、master2

#/opt/hadoop/sbin/hadoop-daemon.sh start zkfc

(6)slave节点启动datanode

  • slave1、slave2、slave3

#/opt/hadoop/sbin/hadoop-daemon.sh start datanode

(7)master节点启动yarn

  • master1

#/opt/hadoop/sbin/start-yarn.sh

(8)master节点启动historyserver

  • master1

./mr-jobhistory-daemon.sh start historyserver

集群已启动。在各服务器执行jps查看,两个master上各一个namenode,形成namenode高可用,实现故障自动切换。
