Hadoop、Hbase、Zookeeper安裝
前言
由於Nutch2.0開始,已經可以將索引結果存入Hbase,但由於Hbase內建的Zookeeper似乎沒有太穩定,因此自己手動整合才是王道...
安裝環境
- OS: Ubuntu12.04
- Java: OpenJDK 6
套件版本
- Hadoop 1.0.3
- Hbase 0.90.6(沒有選用最新的原因是因為Nutch官網上有提到0.90.x為他們的測試環境)
- Zookeper 3.3.6
安裝Hadoop
下載&解壓縮Hadoop1.0.3
修改$HAHOOP_HOME/conf/hadoop-env.sh
- 設定JAVA_HOME
export JAVA_HOME=/usr/lib/jvm/java-6-openjdk
修改$HAHOOP_HOME/conf/core-site.xml
<configuration> <property> <name>fs.default.name</name> <value>hdfs://localhost:9000</value> </property> </configuration>
修改$HAHOOP_HOME/conf/mapred-site.xml
<configuration> <property> <name>mapred.job.tracker</name> <value>localhost:9001</value> </property> </configuration>
修改$HAHOOP_HOME/conf/hdfs-site.xml
<configuration> <property> <name>dfs.replication</name> <value>1</value> </property> <property> <name>dfs.support.append</name> <value>true</value> </property> </configuration>
格式化HDFS
shunfa@shunfa-vmmVBox:/opt/hadoop-1.0.3$ bin/hadoop namenode -format
啟動Hadoop
shunfa@shunfa-vmmVBox:/opt/hadoop-1.0.3$ bin/start-all.sh
安裝Zookeeper
下載並解壓縮zookeeper到/opt/
建立zookeeper運作時需要的目錄並複製預設設定檔
~$ cd /opt/zookeeper-3.3.6/ ~$ sudo mkdir /var/zookeeper ~$ sudo chown -R shunfa:shunfa /var/zookeeper ~$ sudo chown -R shunfa:shunfa /opt/zookeeper-3.3.6/ ~$ cp conf/zoo_sample.cfg conf/zoo.cfg
修改zoo.cfg
tickTime=2000 initLimit=10 syncLimit=5 dataDir=/var/zookeeper clientPort=2181
啟動
~$ /opt/zookeeper-3.3.6/bin/zkServer.sh start
安裝Hbase
下載並解壓縮Hbase到/opt/
修改 /opt/hbase-0.90.6/conf/hbase-env.sh
export HBASE_MANAGES_ZK=false export JAVA_HOME=/usr/lib/jvm/java-6-openjdk export HBASE_HEAPSIZE=256 export HBASE_CLASSPATH=/opt/hadoop-1.0.3/conf
修改 /opt/hbase-0.90.6/conf/hbase-site.xml
<configuration> <property> <name>hbase.rootdir</name> <value>hdfs://localhost:54310/hbase</value> </property> <property> <name>hbase.zookeeper.property.dataDir</name> <value>/var/zookeeper</value> </property> <property> <name>dfs.support.append</name> <value>true</value> </property> <property> <name>hbase.cluster.distributed</name> <value>true</value> </property> <property> <name>hbase.zookeeper.property.clientPort</name> <value>2181</value> </property> </configuration>
複製相關lib
~$ cp $HADOOP_HOME/lib/commons-configuration-1.6.jar $HBASE_HOME/lib/ ~$ cp $HADOOP_HOME/hadoop-core-1.0.3.jar $HBASE_HOME/lib/
啟動
~$ /opt/hbase-0.90.6/bin/start-hbase.sh
完成
- 執行結果如下:
shunfa@shunfa-vmmVBox:~$ jps 23659 HRegionServer 21788 NameNode 22230 JobTracker 22148 SecondaryNameNode 5585 Jps 21972 DataNode 22410 TaskTracker 23069 QuorumPeerMain
