How to install Apache Kafka on Ubuntu 14.04

Install JRE:

sudo apt-get update
sudo apt-get install default-jre

Install Zoo Keeper:

sudo apt-get install zookeeperd

Restrict it to only localhost:

sudo vim /etc/zookeeper/conf/zoo.cfg 

And fix line:

clientPortAddress=127.0.0.1

And apply changes:

sudo service zookeeper restart

Then we need to download pre-compiled Kafka binaries and install them.

wget 'http://apache-mirror.rbc.ru/pub/apache/kafka/2.2.0/kafka_2.11-2.2.0.tgz' -Okafka_2.11-2.2.0.tgz
sudo tar -xf kafka_2.11-2.2.0.tgz -C /opt
cd /opt/kafka_2.11-2.2.0/

Create user for Kafka:

sudo useradd kafka -m 

Change permissions:

sudo chown -R kafka:kafka /opt/kafka_2.11-2.2.0/

Create folder for kafka logs:

sudo mkdir /tmp/kafka-logs
sudo chown kafka:kafka /tmp/kafka-logs

Move configuration to proper place:

sudo mkdir /etc/kafka
sudo cp config/server.properties /etc/kafka

Create Kafka Upstart script:

sudo vim /etc/init/kafka.conf

 With following content:

description "Kafka Broker"
start on runlevel [2345]
stop on starting rc RUNLEVEL=[016]
respawn
respawn limit 2 5
env HOME=/etc/kafka
env KAFKA_HOME=/opt/kafka_2.11-2.2.0/
umask 007
kill timeout 300
pre-start script
    #Sanity checks
    [ -r $HOME/server.properties ]
end script
setuid kafka
setgid kafka
exec $KAFKA_HOME/bin/kafka-server-start.sh $HOME/server.properties

And finally start Kafka:

sudo service kafka start
