Apache Phoenix介绍&安装

概述

Phoenix是构建在HBase上的一个SQL层，能让我们用标准的JDBC APIs而不是HBase客户端APIs来创建表，插入数据和对HBase数据进行查询。Phoenix完全使用Java编写，作为HBase内嵌的JDBC驱动。Phoenix查询引擎会将SQL查询转换为一个或多个HBase扫描，并编排执行以生成标准的JDBC结果集。下载apache-phoenix-4.10.0-HBase-1.2-bin.tar.gz,注意下载的Phoenix版本必须和hbase目标版本保持一致。更多版本 http://archive.apache.org/dist/phoenix

安装

安装好HDFS，并且保证HDFS正常运行
必须配置HADOOP_HOME，因为HBase需要通过该变量定位HADOOP服务
安装Zookeeper（存储集群的元数据信息HMaster和HRegionServer）

[root@CentOS ~]# tar -zxf zookeeper-3.4.6.tar.gz  -C /usr/
[root@CentOS ~]# mkdir zkdata
[root@CentOS ~]# touch /usr/zookeeper-3.4.6/conf/zoo.cfg
[root@CentOS ~]# vi /usr/zookeeper-3.4.6/conf/zoo.cfg
tickTime=2000
dataDir=/root/zkdata
clientPort=2181
[root@CentOS ~]# /usr/zookeeper-3.4.6/bin/zkServer.sh start zoo.cfg
JMX enabled by default
Using config: /usr/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@CentOS ~]# /usr/zookeeper-3.4.6/bin/zkServer.sh status zoo.cfg
JMX enabled by default
Using config: /usr/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: standalone

安装配置hbase

[root@CentOS ~]# tar -zxf hbase-1.2.4-bin.tar.gz -C /usr/
[root@CentOS ~]# cd /usr/hbase-1.2.4/
[root@CentOS hbase-1.2.4]# vi conf/hbase-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <property>
                <name>hbase.rootdir</name>
                <value>hdfs://CentOS:9000/hbase</value>
    </property>
    <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
    </property>
    <property>
                <name>hbase.zookeeper.quorum</name>
                <value>CentOS</value>
    </property>
    <property>
                <name>hbase.zookeeper.property.clientPort</name>
                <value>2181</value>
    </property>
    
    <property>
		<name>hbase.table.sanity.checks</name>
		<value>false</value>
	</property>
</configuration>

[root@CentOS hbase-1.2.4]#  vi conf/regionservers

CentOS

[root@CentOS ~]# vi .bashrc
JAVA_HOME=/usr/java/latest
HADOOP_HOME=/usr/hadoop-2.9.2
HBASE_HOME=/usr/hbase-1.2.4
ZOOKEEPER_HOME=/usr/zookeeper-3.4.6
PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HBASE_HOME/bin:$ZOOKEEPER_HOME/bin
CLASSPATH=.
export JAVA_HOME
export HADOOP_HOME
export HBASE_HOME
export PATH
export CLASSPATH
export ZOOKEEPER_HOME
[root@CentOS ~]# source .bashrc

[root@CentOS hbase-1.2.4]# vi conf/hbase-env.sh
export HBASE_MANAGES_ZK=false

解压Phoenix安装包

[root@CentOS ~]# tar -zxf apache-phoenix-4.10.0-HBase-1.2-bin.tar.gz -C /usr/
[root@CentOS apache-phoenix-4.10.0-HBase-1.2-bin]# cp phoenix-4.10.0-HBase-1.2-server.jar /usr/hbase-1.2.4/lib
[root@CentOS apache-phoenix-4.10.0-HBase-1.2-bin]# cp phoenix-4.10.0-HBase-1.2-server.jar /usr/hbase-1.2.4/lib
[root@CentOS hbase-1.2.4]# ls -l lib/phoenix-4.10.0-HBase-1.2-*
-rw-r--r--. 1 root root 85701658 1月  10 13:50 lib/phoenix-4.10.0-HBase-1.2-client.jar
-rw-r--r--. 1 root root 25013545 1月  10 13:50 lib/phoenix-4.10.0-HBase-1.2-server.jar

启动Hbase服务

[root@CentOS ~]# cd /usr/hbase-1.2.4/
[root@CentOS hbase-1.2.4]#  ./bin/start-hbase.sh
[root@CentOS hbase-1.2.4]#  jps
93714 QuorumPeerMain
3764 SecondaryNameNode

1、链接Phoenix

[root@CentOS ~]# cd /usr/apache-phoenix-4.10.0-HBase-1.2-bin/
[root@CentOS apache-phoenix-4.10.0-HBase-1.2-bin]# ./bin/sqlline.py CentOS
