hadoop的單機版安裝和HBase的搭建

1. 安裝jdk1.7的環境   下載hadoop. hadoop-2.5.2.tar.gz版本html

2.進入hadoop的網站,點擊左下角的Documentation,找到對應的版本 ,點擊進入,找到Single Node Setup 的說明文檔,按照文檔說明開始配置java

  1. 編輯etc/hadoop/hadoop-env.sh 
  2. # set to the root of your Java installation
      export JAVA_HOME=/usr/java/latest (java的環境位置)
  3. Use the following:node

    etc/hadoop/core-site.xml:web

    <configuration>
        <property>
            <name>fs.defaultFS</name>
            <value>hdfs://localhost:8020</value> (ip地址)
        </property>
    </configuration>

    etc/hadoop/hdfs-site.xml:apache

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

配置YARN on Single Nodeoop

Configure parameters as follows:網站

etc/hadoop/mapred-site.xml:code

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

etc/hadoop/yarn-site.xml:orm

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

 配置 hadoop.tmp.dirserver

在hadoop文件中建立data目錄

在etc/hadoop/core-site.xml:中添加  

<property>
        <name>hadoop.tmp.dir</name>
        <value>/bigdata/softwares/hadoop-2.5.2/data/tmp</value>
    </property>

執行操做

  1. Format the filesystem: 格式化信息 
    $ bin/hdfs namenode -format
  2. Start NameNode daemon and DataNode daemon:
    $ sbin/start-dfs.sh
  3. $ sbin/start-yarn.sh
  4. The hadoop daemon log output is written to the $HADOOP_LOG_DIR directory (defaults to $HADOOP_HOME/logs).

  5. Browse the web interface for the NameNode; by default it is available at:
    • NameNode - http://localhost:50070/

 hbase

 Example hbase-site.xml for Standalone HBase

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://ip:8080/data</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/bigdata/softwares/hbase-1.2.3/data/zkData</value>
  </property>
</configuration>
<property>
  <name>hbase.cluster.distributed</name>
  <value>true</value>
</property>

修改 regionserver 中的ip地址

bin/hbase-daemon.sh start zookeeper

 bin/hbase-daemon.sh start master

 bin/hbase-daemon.sh start regionserver

http://192.168.1.23:16030/rs-status 端口邊了
