### --- HBase配置文件参数

~~~     # 注意：要求hbase的hbase.zookeeper.quorum值必须只能是host1、host2、...
~~~     # 不允许出现host:2181；hbase-site.xml文件：

### --- 修改hbase配置文件

[root@hadoop01 ~]# vim /opt/yanqi/servers/hbase-1.3.1/conf/hbase-site.xml
<configuration>

        <!-- 指定hbase在HDFS上存储的路径 -->
        <property>
                <name>hbase.rootdir</name>
                <value>hdfs://hadoop01:9000/hbase</value>
        </property>

        <!-- 指定hbase是分布式的 -->
        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>

        <!-- 指定zk的地址，多个用“,”分割 -->
        <property>
                <name>hbase.zookeeper.quorum</name>
                <value>hadoop01,hadoop02,hadoop03</value>
        </property>

</configuration>

二、Kylin配置资源准备

### --- 下载kylin版本包并解压到安装目录

~~~     # 下载kylin版本包
[root@hadoop01 software]# wget https://archive.apache.org/dist/kylin/apache-kylin-3.1.1/apache-kylin-3.1.1-bin-hbase1x.tar.gz
~~~     # 解压版本包
[root@hadoop01 software]# tar -zxvf apache-kylin-3.1.1-bin-hbase1x.tar.gz -C ../servers/
~~~     # 修改配置目录名称
[root@hadoop01 ~]# cd /opt/yanqi/servers/
[root@hadoop01 servers]# mv apache-kylin-3.1.1-bin-hbase1x kylin-3.1.1

### --- 添加环境变量，并使之生效

~~~     # 配置kylin系统环境变量
[root@hadoop01 ~]# vim /etc/profile
##KYLIN_HOME
export KYLIN_HOME=/opt/yanqi/servers/kylin-3.1.1
export PATH=$PATH:$KYLIN_HOME/bin

~~~     # 使环境变量生效

[root@hadoop01 ~]# source /etc/profile

三、kylin安装部署

### --- 增加kylin依赖组件的配置

~~~     # 添加kylin依赖组件
[root@hadoop01 ~]# cd $KYLIN_HOME/conf

[root@hadoop01 conf]# ln -s $HADOOP_HOME/etc/hadoop/hdfs-site.xml hdfs-site.xml
[root@hadoop01 conf]# ln -s $HADOOP_HOME/etc/hadoop/core-site.xml core-site.xml
[root@hadoop01 conf]# ln -s $HBASE_HOME/conf/hbase-site.xml hbase-site.xml
[root@hadoop01 conf]# ln -s $HIVE_HOME/conf/hive-site.xml hive-site.xml
[root@hadoop01 conf]# ln -s $SPARK_HOME/conf/spark-defaults.conf spark-defaults.conf

### --- 修改 kylin.sh

~~~     # 修改kylin.sh配置文件
[root@hadoop01 ~]# vim $KYLIN_HOME/bin/kylin.sh
~~~第21~24行添加如下内容：
export HADOOP_HOME=/opt/yanqi/servers/hadoop-2.9.2
export HIVE_HOME=/opt/yanqi/servers/hive-2.3.7
export HBASE_HOME=/opt/yanqi/servers/hbase-1.3.1
export SPARK_HOME=/opt/yanqi/servers/spark-2.4.5

### --- 检查依赖

[root@hadoop01 ~]# $KYLIN_HOME/bin/check-env.sh
 ~~~输出参数
 Retrieving hadoop conf dir...
...................................................[PASS]
KYLIN_HOME is set to /opt/yanqi/servers/kylin-3.1.1
Checking HBase
...................................................[PASS]
Checking hive
...................................................[PASS]
Checking hadoop shell
...................................................[PASS]
Checking hdfs working dir
...................................................[PASS]

Checking environment finished successfully. To check again, run 'bin/check-env.sh' manually.

四、启动集群

### --- 启动 zookeeper（Hadoop01）

~~~     # 启动zookeeper集群
[root@hadoop01 ~]# ./zk.sh start

### --- 启动 HDFS（Hadoop01）

[root@hadoop01 ~]# nohup hive --service metastore &
~~~     # 查看metastore进程
[root@hadoop01 ~]# lsof -i:9083

### --- 启动Yarn history server（Hadoop01）

~~~     # 启动yarn history server：Hadoop01
