hbase 安装笔记

1、安装

在官方镜像站点下载hbase2.0，地址：https://www.apache.org/dyn/closer.lua/hbase/

解压
tar xzvf hbase-2.0.4-bin.tar.gz

设置好JAVA_HOME环境变量，或者直接在hbase的配置文件(conf/hbase-env.sh)里设置JAVA_HOME

设置HBASE_HOME，这个不是必须。

本例是在/etc/profile文件里追加java环境变量，设置后需要source /etc/profile使设置生效，或者重新登录

#set java environment
JAVA_HOME=/home/java/jdk1.8.0_172
JRE_HOME=/home/java/jdk1.8.0_172/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH


#set hbase environment
export HBASE_HOME=/opt/hbase-2.0.4
export PATH=$PATH:$HBASE_HOME/bin

2、配置hbase-site.xml

vi $HBASE_HOME/conf/hbase-site.xml 

<configuration>
  <property>
    #hbase的数据目录
    <name>hbase.rootdir</name>
    <value>file:///opt/hbase_data</value> #本例使用本地文件系统，如果是需要把数据存在hdfs上，需配置相应的hdfs目录，例如：hdfs://namenode.example.org:9000/hbase
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/opt/hbase_data/zookeeper</value>
  </property>
  <property>
    <name>hbase.unsafe.stream.capability.enforce</name>
    <value>false</value>
  </property>
</configuration>

3、启动hbase，在standalone模式下hbase所有守护进程都运行在一个JVM里，例如：HMaster、HRegionServer、ZooKeeper daemon等。

执行在hbase的bin目录下的脚本 bin/start-hbase.sh



启动后通过jps可以看到hMaster的进程

[root@bigdata-senior01 ~]# jps
2082 Jps
1523 HMaster

4、进入shell，通过hbase的bin目录下的bin/hbase shell启动

[hadoop@bigdata-senior01 conf]$ hbase shell
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/opt/hbase-2.0.4/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/opt/hadoop/hadoop-3.2.0/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

5、检查hbase是否正常

hbase(main):004:0> status
1 active master, 0 backup masters, 1 servers, 0 dead, 2.0000 average load
