Hbase 安装模式介绍

单机模式
1> Hbase 不使用 HDFS, 仅使用本地文件系统
2> ZooKeeper 与 Hbase 运行在同一个 JVM 中

分布式模式
– 伪分布式模式
1> 所有进程运行在同一个节点上, 不同进程运行在不同的 JVM 当中
2> 比较适合实验测试
– 完全分布式模式
1> 进程运行在多个服务器集群中
2> 分布式依赖于 HDFS 系统,因此布署 Hbase 之前一定要有一个正常工作的 HDFS 集群

Linux 环境准备

关闭防火墙和 SELinux

# service iptables stop

# chkconfig iptables off

# vim /etc/sysconfig/selinux

SELINUX=disabled

配置主机名及主机名绑定

# vim /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=hbase

# vim /etc/hosts

192.168.244.30 hbase

SSH 免密码登录

# ssh-keygen

一直按 Enter 键

# ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.244.30

安装 jdk

# tar xvf jdk-7u79-linux-x64.tar.gz -C /usr/local/

# vim /etc/profile

export JAVA_HOME=/usr/local/jdk1.7.0_79
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

# source /etc/profile

Hadoop 的安装部署

下载地址:http://hadoop.apache.org/releases.html

在这里,选择 2.5.2 版本

# wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.5.2/hadoop-2.5.2.tar.gz

# tar xvf hadoop-2.5.2.tar.gz -C /usr/local/

# cd /usr/local/hadoop-2.5.2/

# vim etc/hadoop/hadoop-env.sh

export JAVA_HOME=/usr/local/jdk1.7.0_79

 

配置 HDFS

# mkdir /usr/local/hadoop-2.5.2/data/

# vim etc/hadoop/core-site.xml

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://192.168.244.30:8020</value>
    </property>
    <property>
        <name>hadoop.tmp.dir</name>
        <value>/usr/local/hadoop-2.5.2/data/tmp</value>
    </property>
</configuration> 

# vim etc/hadoop/hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
</configuration>

配置 YARN

# mv etc/hadoop/mapred-site.xml.template etc/hadoop/mapred-site.xml

# vim etc/hadoop/mapred-site.xml

<configuration>
    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
</configuration>

 

# vim etc/hadoop/yarn-site.xml

<configuration>
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
</configuration>

启动 HDFS

初始化文件系统

# bin/hdfs namenode -format

...
16/09/25 20:33:02 INFO common.Storage: Storage directory /tmp/hadoop-root/dfs/name has been successfully formatted.
...

输出上述信息即代表文件系统初始化成功

启动 NameNod 和 DataNode 进程

# sbin/start-dfs.sh

启动 YARN

# sbin/start-yarn.sh 

starting yarn daemons
starting resourcemanager, logging to /usr/local/hadoop-2.5.2/logs/yarn-root-resourcemanager-hbase.out
localhost: starting nodemanager, logging to /usr/local/hadoop-2.5.2/logs/yarn-root-nodemanager-hbase.out

通过 jps 查看各进程是否启动成功

# jps

2421 NodeManager
2339 ResourceManager
1924 NameNode
2029 DataNode
2170 SecondaryNameNode
2721 Jps

 

也可通过访问 http://192.168.244.30:50070/ 查看 hdfs 是否启动成功

HBase 的伪分布式安装

 

Hbase 的安装部署

下载地址:http://mirror.bit.edu.cn/apache/hbase/1.2.3/hbase-1.2.3-bin.tar.gz

在这里,下载的是 1.2.3 版本

关于 hbase 和 hadoop 的版本对应信息,可参考官档的说明

http://hbase.apache.org/book/configuration.html#basic.prerequisites

# wget http://mirror.bit.edu.cn/apache/hbase/1.2.3/hbase-1.2.3-bin.tar.gz

# tar xvf hbase-1.2.3-bin.tar.gz -C /usr/local/

# cd /usr/local/hbase-1.2.3/

# vim conf/hbase-env.sh

export JAVA_HOME=/usr/local/jdk1.7.0_79

配置 Hbase

# mkdir /usr/local/hbase-1.2.3/data

# vim conf/hbase-site.xml 

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://192.168.244.30:8020/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/usr/local/hbase-1.2.3/data/zookeeper</value>
  </property>
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
</configuration> 

# vim conf/regionservers 

192.168.244.30

启动 Hbase

# bin/hbase-daemon.sh start zookeeper

starting zookeeper, logging to /usr/local/hbase-1.2.3/bin/../logs/hbase-root-zookeeper-hbase.out

# bin/hbase-daemon.sh start master

starting master, logging to /usr/local/hbase-1.2.3/bin/../logs/hbase-root-master-hbase.out

# bin/hbase-daemon.sh start regionserver

starting regionserver, logging to /usr/local/hbase-1.2.3/bin/../logs/hbase-root-regionserver-hbase.out

通过 jps 查看新增的 java 进程

# jps

2421 NodeManager
2975 HQuorumPeer
3302 HRegionServer
3051 HMaster
2339 ResourceManager
1924 NameNode
2029 DataNode
2170 SecondaryNameNode
3332 Jps

可以看出,新增了 HQuorumPeer,HRegionServer 和 HMaster 三个进程。
