【大数据】基于Hadoop的HBase的安装（转）

https://note.youdao.com/share/?id=c27485373a08517f7ad2e7ec901cd8d5&type=note#/

安装前先确认HBse和Hadoop版本的对应关系

环境配置

export JAVA_HOME=/usr/local/jdk
export HADOOP_HOME=/usr/local/hadoop
export HBASE_HOME=/usr/local/hbase
export HIVE_HOME=/usr/local/hive

Hadoop

修改${HADOOP_HOME}/etc/hadoop/hadoop-env.sh

export JAVA_HOME=/usr/local/jdk

修改 ${HADOOP_HOME}/etc/hadoop/core-site.xml

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>

修改 ${HADOOP_HOME}/etc/hadoop/hdfs-site.xml

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

测试是否可以不用密码直接登录localhost

ssh localhost

如果不可以需要执行以下命令

ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys

执行命令

${HADOOP_HOME}/bin/hdfs namenode -format

启动

${HADOOP_HOME}/sbin/start-dfs.sh

停止

${HADOOP_HOME}/sbin/stop-dfs.sh

访问网址：http://localhost:50070/

HBase

修改 ${HBASE_HOME}/conf/hbase-env.sh

export JAVA_HOME=/usr/local/jdk

修改 ${HBASE_HOME}/conf/hbase-site.xml

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://localhost:9000/hbase</value>
  </property>
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
  <property>
    <name>hbase.zookeeper.quorum</name>
	<value>localhost</value>
  </property>
</configuration>

配置服务器的etc/hostname和etc/hosts（一定要配置正确，否则远程无法连接）

启动

${HBASE_HOME}/bin/start-hbase.sh

停止

${HBASE_HOME}/bin/stop-hbase.sh

测试

bin/hbase shell

create 'users','basic','business'
put 'users','zhangsan','basic:name','张三'
get 'users','zhangsan'
scan 'users'
put 'users','zhangsan','basic:sex','Male'
put 'users','zhangsan','business:company','STW'
put 'users','zhangsan','basic:sex','Female'
delete 'users','zhangsan','basic:sex'
deleteall 'users','zhangsan'
count 'users'

Hive

${HADOOP_HOME}/bin/hadoop fs -mkdir       /tmp
${HADOOP_HOME}/bin/hadoop fs -mkdir       /user
${HADOOP_HOME}/bin/hadoop fs -mkdir       /user/hive
${HADOOP_HOME}/bin/hadoop fs -mkdir       /user/hive/warehouse
${HADOOP_HOME}/bin/hadoop fs -chmod g+w   /tmp
${HADOOP_HOME}/bin/hadoop fs -chmod g+w   /user/hive/warehouse
