1. 从官网下载 apache-kylin-2.0.0-bin-cdh57.tar.gz 放到每台需要安装kylin 服务的机器

[hadoop@hadoop3 cdh5.12.0]$ sudo tar -zxvf apache-kylin-2.0.0-bin-cdh57.tar.gz -C /opt/

[hadoop@hadoop3 opt]$ sudo chown -R hdfs:hdfs /opt/apache-kylin-2.0.0-bin/

[hadoop@hadoop3 apache-kylin-2.0.0-bin]$ sudo ln -s /opt/apache-kylin-2.0.0-bin/ /opt/kylin

2. 配置环境变量

[hadoop@hadoop3 kylin]$ vi ~/.bashrc
