[HBase]完全分布式安装过程详解

HBase版本：0.90.5

Hadoop版本：0.20.2

OS版本：CentOS

安装方式：完全分布式（1个master，3个regionserver）

1）解压缩HBase安装文件

[hadoop@node01 ~]$ tar -zxvf hbase-0.90.5.tar.gz

解压缩成功后的HBase主目录结构如下：

[hadoop@node01 hbase-0.90.5]$ ls -l

total 3636

drwxr-xr-x. 3 hadoop root 4096 Dec 8 2011 bin

-rw-r--r--. 1 hadoop root 217043 Dec 8 2011 CHANGES.txt

-rw-r--r--. 1 hadoop root 803 Dec 8 2011 NOTICE.txt

-rw-r--r--. 1 hadoop root 31073 Dec 8 2011 pom.xml

-rw-r--r--. 1 hadoop root 1358 Dec 8 2011 README.txt

drwxr-xr-x. 8 hadoop root 4096 Dec 8 2011 src

2）配置hbase-env.sh

[hadoop@node01 conf]$ vi hbase-env.sh

# The java implementation to use. Java 1.6 required.

export JAVA_HOME=/usr/java/jdk1.6.0_38

# Extra Java CLASSPATH elements. Optional.

export HBASE_CLASSPATH=/home/hadoop/hadoop-0.20.2/conf

3）配置hbase-site.xml

[hadoop@node01 conf]$ vi hbase-site.xml

hbase.rootdir

hdfs://node01:9000/hbase

hbase.cluster.distributed

true

hbase.zookeeper.quorum

node01,node02,node03,node04

hbase.zookeeper.property.dataDir

/var/zookeeper

4）配置regionservers

[hadoop@node01 conf]$ vi regionservers

node02

node03

node04

5) 替换Jar包

[hadoop@node01 lib]$ mv hadoop-core-0.20-append-r1056497.jar hadoop-core-0.20-append-r1056497.sav

[hadoop@node01 lib]$ cp ../../hadoop-0.20.2/hadoop-0.20.2-core.jar .

[hadoop@node01 lib]$ ls

activation-1.1.jar commons-net-1.4.1.jar jasper-compiler-5.5.23.jar jetty-util-6.1.26.jar slf4j-api-1.5.8.jar

asm-3.1.jar core-3.1.1.jar jasper-runtime-5.5.23.jar jruby-complete-1.6.0.jar slf4j-log4j12-1.5.8.jar

avro-1.3.3.jar guava-r06.jar jaxb-api-2.1.jar jsp-2.1-6.1.14.jar stax-api-1.0.1.jar

commons-el-1.0.jar jackson-core-asl-1.5.5.jar jersey-json-1.4.jar log4j-1.2.16.jar zookeeper-3.3.2.jar

commons-httpclient-3.1.jar jackson-jaxrs-1.5.5.jar jersey-server-1.4.jar protobuf-java-2.3.0.jar

commons-lang-2.5.jar jackson-mapper-asl-1.4.2.jar jettison-1.1.jar ruby

commons-logging-1.1.1.jar jackson-xc-1.5.5.jar jetty-6.1.26.jar servlet-api-2.5-6.1.14.jar

6) 向其它3个结点复制Hbase相关配置

[hadoop@node01 ~]$scp -r ./hbase-0.90.5 node02:/home/hadoop

[hadoop@node01 ~]$scp -r ./hbase-0.90.5 node03:/home/hadoop

[hadoop@node01 ~]$scp -r ./hbase-0.90.5 node04:/home/hadoop

7) 添加HBase相关环境变量 （所有结点）

[hadoop@node01 conf]$ su - root

Password:

[root@node01 ~]# vi /etc/profile

export HBASE_HOME=/home/hadoop/hbase-0.90.5

export PATH=$PATH:$HBASE_HOME/bin

8）启动Hadoop，创建HBase主目录

[hadoop@node01 ~]$ $HADOOP_INSTALL/bin/start-all.sh

starting namenode, logging to /home/hadoop/hadoop-0.20.2/bin/../logs/hadoop-hadoop-namenode-node01.out

9）启动HBase

[hadoop@node01 conf]$ start-hbase.sh
