hadoop 2.2、 hbase0.94.18 集群安装，hadoophbase0.94.18
这里我们安装三台的集群：集群ip：192.168.157.132-134
master：192.168.157.132
slaves：192.168.157.133-134
hbase 依赖zookeeper自行安装。
1、配置ssh 无密码 免登陆
1>安装ssh：132 、134、 133
yum install openssh-clients
2> 配置无密码免登陆：132 、134、 133
[root@localhost ~]# ssh-keygen -t rsa
一路回车
[root@localhost ~]# cd /root/.ssh/
[root@localhost .ssh]# cat id_rsa.pub >> authorized_keys
[root@localhost .ssh]# scp authorized_keys root@192.168.157.132:/root/.ssh
[root@localhost .ssh]# scp authorized_keys root@192.168.157.133:/root/.ssh
[root@localhost .ssh]# scp authorized_keys root@192.168.157.134:/root/.ssh 修改权限三台
[root@localhost ~]# chmod 700 .ssh/
[root@localhost ~]# chmod 600 ~/.ssh/authorized_keys
2、修改机器名称
1> 通过命令修改：重启失效
[root@localhost .ssh]# hostname dev-157-132
[root@localhost .ssh]# hostname
dev-157-132 2> 修改配置文件：永久生效 [root@localhost .ssh]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=dev-157-132
GATEWAY=192.168.248.2543>三台先后经过两个步骤修改即可：dev-157-132 dev-157-133 dev-157-134
4>修改三台/etc/hosts
[root@localhost .ssh]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.157.132 dev-157-132
192.168.157.133 dev-157-133
192.168.157.134 dev-157-1343、关闭防火墙（三台）
service iptables stop
4、安装JDK 略...
5、安装hadoop2.2.0
[root@dev-157-132 servers]# tar -xf hadoop-2.2.0.tar.gz [root@dev-157-132 servers]# cd hadoop-2.2.0/etc/hadoop1> 修改hadoop-env.sh
[root@dev-157-132 hadoop]# vim hadoop-env.sh
export JAVA_HOME=/export/servers/jdk1.6.0_25 （这java_home）
其他默认2> 修改core-site.xml
[root@dev-157-132 hadoop]# vim core-site.xml

[root@dev-157-132 hadoop]# vim slaves
dev-157-133
dev-157-1347> scp 到slave机器上
scp -r hadoop-2.2.0 root@192.168.157.133:/export/servers scp -r hadoop-2.2.0 root@192.168.157.134:/export/servers
8> 设置三台环境变量
[root@dev-157-132 hadoop]# vim /etc/profile export HADOOP_HOME=/export/servers/hadoop-2.2.0 export HADOOP_CONF_DIR=/export/servers/hadoop-2.2.0/etc/hadoop export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH [root@dev-157-132 hadoop]# source /etc/profile
9> 格式化 hdfs 在master
hadoop namenode -format
6 、启动hadoop 在 master
start-all.sh This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh 14/12/23 11:18:27 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable Starting namenodes on [dev-157-132] dev-157-132: starting namenode, logging to /export/servers/hadoop-2.2.0/logs/hadoop-root-namenode-dev-157-132.out dev-157-134: starting datanode, logging to /export/servers/hadoop-2.2.0/logs/hadoop-root-datanode-dev-157-134.out dev-157-133: starting datanode, logging to /export/servers/hadoop-2.2.0/logs/hadoop-root-datanode-dev-157-133.out Starting secondary namenodes [0.0.0.0] 0.0.0.0: starting secondarynamenode, logging to /export/servers/hadoop-2.2.0/logs/hadoop-root-secondarynamenode-dev-157-132.out 14/12/23 11:18:56 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable starting yarn daemons starting resourcemanager, logging to /export/servers/hadoop-2.2.0/logs/yarn-root-resourcemanager-dev-157-132.out dev-157-134: starting nodemanager, logging to /export/servers/hadoop-2.2.0/logs/yarn-root-nodemanager-dev-157-134.out dev-157-133: starting nodemanager, logging to /export/servers/hadoop-2.2.0/logs/yarn-root-nodemanager-dev-157-133.out [root@dev-157-132 hbase-0.94.18-security]# jps 8100 NameNode 8973 Jps 8269 SecondaryNameNode 8416 ResourceManager
7、安装hbase
[root@dev-157-132 servers]# tar -zxvf hbase-0.94.18-security.tar.gz [root@dev-157-132 servers]# cd hbase-0.94.18-security/conf/
1>修改配置
[root@dev-157-132 conf]# vim hbase-env.sh
export JAVA_HOME=/export/servers/jdk1.6.0_25
配置内存大小
export HBASE_MASTER_OPTS="-Xms512m -Xmx512m $HBASE_MASTER_OPTS"
export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS $HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10102 -Xmn256m -Xms256m -Xmx256m -XX:SurvivorRatio=4"
export HBASE_MANAGES_ZK=false
[root@dev-157-132 conf]# vim hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://dev-157-132:9100/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/export/servers/hbase-0.94.18-security/data/tmp</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>ip ,ip</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
<property>
<name>hbase.regionserver.handler.count</name>
<value>30</value>
</property>
</configuration>
[root@dev-157-132 conf]# vim regionservers
dev-157-133
dev-157-1342> cp到其他机器
scp 之前 替换 hbase lib相关的jar 为安装的hadoop 版本的jar
[root@dev-157-132 servers]# scp -r hbase-0.94.18-security root@192.168.157.132:/export/servers/ [root@dev-157-132 servers]# scp -r hbase-0.94.18-security root@192.168.157.134:/export/servers/
3> 设置hbase_home(三台)
[root@dev-157-132 hadoop]# vim /etc/profile export HBASE_HOME=/export/servers/hbase-0.94.18-security
8、启动hbase
[root@dev-157-132 servers]# ./hbase-0.94.18-security/bin/start-hbase.sh starting master, logging to /export/servers/hbase-0.94.18-security/logs/hbase-root-master-dev-157-132.out dev-157-134: starting regionserver, logging to /export/servers/hbase-0.94.18-security/bin/../logs/hbase-root-regionserver-dev-157-134.out dev-157-133: starting regionserver, logging to /export/servers/hbase-0.94.18-security/bin/../logs/hbase-root-regionserver-dev-157-133.out
