HBase的安装和编程实践

HBase的安装和编程实践

1.HBase2.4.2安装

1.1 解压安装包

解压到/usr/local

[root@hadoop-master ~]# tar -zvxf hbase-2.4.2-bin.tar.gz -C /usr/local/

1.2 将解压的文件名hbase-2.4.2改为hbase

[root@hadoop-master local]# mv hbase-2.4.2/ hbase

1.3 配置环境变量

[root@hadoop-master hbase]# vim ~/.bashrc
[root@hadoop-master hbase]# cat ~/.bashrc 
# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi
export PATH=$PATH:/usr/local/hbase/bin
[root@hadoop-master hbase]# source ~/.bashrc

1.4 查看HBase版本，确定hbase安装成功

[root@hadoop-master ~]# /usr/local/hbase/bin/hbase version
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/hadoop/hadoop-3.1.4/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/local/hbase/lib/client-facing-thirdparty/slf4j-log4j12-1.7.30.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

2.HBase配置

2.1 伪分布式配置

1.配置/usr/local/hbase/conf/hbase-env.sh

[root@hadoop-master ~]# vim /usr/local/hbase/conf/hbase-env.sh

配置JAVA_HOME，HBASE_CLASSPATH，HBASE_MANAGES_ZK

export JAVA_HOME=/usr/java/jdk1.8.0_281-amd64#这是我本机的JDK安装路径
export HBASE_CLASSPATH=/usr/local/hbase/conf 
export HBASE_MANAGES_ZK=true

2.配置/usr/local/hbase/conf/hbase-site.xml

[root@hadoop-master ~]# vim /usr/local/hbase/conf/hbase-site.xml 
[root@hadoop-master ~]# cat /usr/local/hbase/conf/hbase-site.xml 
<?xml version="1.0"?>
