apache kylin 2.1.0+CDH5.8 安装部署教程

作为一个kylin的初学者来说，首要任务是需要安装kylin，本文将给大家讲述如何安装kylin 2.1.0 ，本文参考了kylin的官方文档写的，官方文档

由于目前kylin 2.0开始支持spark，这里会加上spark的详细配置

由于hadoop，hive，hbase版本是cdh5.8 ,我们下载的时候下载cdh的包

1、下载kylin 2.1.0

下载地址：http://www.apache.org/dyn/closer.cgi/kylin/apache-kylin-2.1.0/apache-kylin-2.1.0-bin-cdh57.tar.gz

2、解压文件

tar zxvf apache-kylin-2.1.0-bin-cdh57.tar.gz  /usr/share/apache-kylin/apache-kylin-2.1.0-bin-cdh57cd /usr/share/apache-kylin/apache-kylin-2.1.0-bin-cdh57

3、添加kylin用户，专门用来执行

useradd -g kylin kylinsu kylin

4、配置文件

用户目录下新建hadoop_conf目录，将hadoop，yarn，hive，hbase的site.xml复制到该目录下面

mkdir hadoop_confcp /usr/share/hadoop/conf/*-site.xml /usr/share/apache-kylin/apache-kylin-2.1.0-bin-cdh57/hadoop_conf/cp /usr/share/hbase/conf/hbase-site.xml /usr/share/apache-kylin/apache-kylin-2.1.0-bin-cdh57/hadoop_conf/export KYLIN_HOME=/usr/share/apache-kylin/apache-kylin-2.1.0-bin-cdh57

修改conf/kylin.properties

kylin.env.hadoop-conf-dir=/usr/share/apache-kylin/apache-kylin-2.1.0-bin-cdh57/hadoop_conf/kylin.engine.spark-conf.spark.master=yarnkylin.engine.spark-conf.spark.submit.deployMode=clusterkylin.engine.spark-conf.spark.yarn.queue=defaultkylin.engine.spark-conf.spark.executor.memory=4Gkylin.engine.spark-conf.spark.executor.cores=2kylin.engine.spark-conf.spark.executor.instances=1kylin.engine.spark-conf.spark.eventLog.enabled=truekylin.engine.spark-conf.spark.eventLog.dir=hdfs\:///kylin/spark-historykylin.engine.spark-conf.spark.history.fs.logDirectory=hdfs\:///kylin/spark-historykylin.engine.spark-conf.spark.hadoop.yarn.timeline-service.enabled=falsekylin.engine.spark-conf.spark.yarn.jar=hdfs://localhost:8020/kylin/spark/spark-assembly-1.6.3-hadoop2.6.0-cdh5.8.2.jar

5、启动kylin

当上面的操作执行完成，首先执行check-env.sh 脚本检查环境变量有没有问题

bin/check-env.sh  //检查环境变量bin/kylin.sh start  //启动kylinbin/kylin.sh stop  //停止kylin
