Download and Install Kyligence Enterprise

0. Before proceeding, please make sure the Prerequisite is met.

1. Get Kyligence Enterprise software package. You can visit Kyligence Download Center and choose a version according to your environment.

2. Decide the installation location and the Linux account to run Kyligence Enterprise. All the examples below are based on the following assumptions:

• The installation location is /usr/local/.
• Linux account to run Kyligence Enterprise is root. It is called the Linux account hereafter.

Note: Replace the above with your real installation location and Linux account in all the steps in this guide. For example, the default user for the CDH sandbox should be cloudera rather than root.

3. Copy Kyligence Enterprise software package to your server or VM, and unpack.

cd /usr/local
tar -zxvf Kyligence-Enterprise-{version}.tar.gz

4. Set environment variable KYLIN_HOME to be the folder path where Kyligence Enterprise is unpacked:

export KYLIN_HOME=/usr/local/Kyligence-Enterprise-{version}

5. Create a working directory for Kyligence Enterprise on HDFS and grant the Linux account with the permission with r/w access. The default working directory is /kylin. Also ensure the Linux account has access to its home directory on HDFS.

hdfs dfs -mkdir /kylin
hdfs dfs -chown root /kylin
hdfs dfs -mkdir /user/root
hdfs dfs -chown root /user/root

If necessary, you can modify the path of the Kyligence Enterprise working directory in $KYLIN_HOME/conf/kylin.properties.

Note: If you do not have permission to execute the above commands, you can su to HDFS account and try again.
su hdfs
# then retry the above hdfs dfs commands

rm -f $KYLIN_HOME/conf/profile
ln -sfn $KYLIN_HOME/conf/profile_min $KYLIN_HOME/conf/profile
