How To Install Apache Kafka on Ubuntu 18.04 LTS

Install Apache Kafka on Ubuntu 18

Apache Kafka is a distributed message agent designed to deal with huge volumes of real time information effectively. Unlike traditional agents like ActiveMQ and RabbitMQ, Kafka functions as a bunch of one or more servers that makes it highly scalable and because of the distributed nature, it’s inbuilt fault-tolerance whilst providing greater throughput when compared to its counterparts.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Apache Kafka on a 18.04 LTS (Bionic Beaver) server.

Install Apache Kafka on Ubuntu 18.04 LTS

Step 1. First make sure that all your system packages are up-to-date

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing Java.

Apache Spark requires Java to be installed on your server. By default, Java is not available in Ubuntu’s repository. Add the Oracle Java PPA to Apt with the following command:

add-apt-repository ppa:webupd8team/java
apt-get update -y
apt-get install oracle-java8-installer

Verify the Java version by running the following command:

java -version

Step 3. Installing Zookeeper.

Apache Kafka depends on Zookeeper for cluster management. Hence, prior to starting Kafka, Zookeeper has to be started:

apt-get install zookeeperd

After the installation completes, ZooKeeper will be started as a daemon automatically. By default, it will listen on port 2181:

netstat -ant | grep :2181

You can run the following command to check whether zookeeper is running:

systemctl status zookeeper

Step 4. Download and Installing Apache Kafka on Ubuntu 18.04 LTS.

First, download and extract Kafka from Apache website. You can use wget to download Kafka:

wget http://www-us.apache.org/dist/kafka/1.1.0/kafka_2.12-1.1.0.tgz

Then extract the archive file:

tar xzf kafka_2.12-1.1.0.tgz
mv kafka_2.12-1.1.0 /usr/local/kafka

Start Kafka Server:

cd /usr/local/kafka
bin/zookeeper-server-start.sh config/zookeeper.properties

Now start the Kafka server:

bin/kafka-server-start.sh config/server.properties

...
[2018-06-26 10:59:45,989] INFO Kafka version : 1.0.1 (org.apache.kafka.common.utils.AppInfoParser)
[2018-06-26 10:59:45,995] INFO Kafka commitId : c0518aa65f25317e (org.apache.kafka.common.utils.AppInfoParser)
[2018-06-26 10:59:46,006] INFO [KafkaServer id=0] started (kafka.server.KafkaServer)
 Step 5. Create a Topic on Kafka.

Let’s create a topic named “NewTopic” with a single partition and only one replica:

bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic NewTopic
Created topic "NewTopic".

Now you can see the created topic on Kafka by running the list topic command:

bin/kafka-topics.sh --list --zookeeper localhost:2181
NewTopic

Step 6. Send Messages to Kafka.

The “producer” is the process responsible for put data into our Kafka. The Kafka comes with a command line client that will take input from a file or from standard input and send it out as messages to the Kafka cluster:

Let’s run the producer and then type a few messages into the console to send to the server:

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic NewTopic


>Welcome to kafka
>This is my new topic
>

Step 7. Using Kafka Consumer.

Kafka also has a command line consumer to read data from Kafka cluster and display messages to standard output:

bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic NewTopic --from-beginning

Welcome to kafka
This is my new topic

Congratulation’s! You have successfully installed Apache Kafka. Thanks for using this tutorial for installing Apache Kafka on Ubuntu 18.04 LTS (Bionic Beaver) system. For additional help or useful information, we recommend you to check the official Apache Kafka Documentation.

How To Install Apache Kafka on Ubuntu 16.04 LTS

Install Apache Kafka on Ubuntu 16

Apache Kafka is a distributed message agent designed to deal with huge volumes of real time information effectively. Unlike traditional agents like ActiveMQ and RabbitMQ, Kafka functions as a bunch of one or more servers that makes it highly scalable and because of the distributed nature, it’s inbuilt fault-tolerance whilst providing greater throughput when compared to its counterparts.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Apache Kafka on an Ubuntu 16.04 Xenial Xerus server.

Install Apache Kafka on Ubuntu 16.04 LTS

Step 1. First make sure that all your system packages are up-to-date

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing Java.

Kafka is written in Java, you will need to install Java on your system:

add-apt-repository -y ppa:webupd8team/java

Once you have finished, run the following command to install Java:

apt-get update
apt-get install oracle-java8-installer

Step 3. Installing Zookeeper.

Apache Kafka depends on Zookeeper for cluster management. Hence, prior to starting Kafka, Zookeeper has to be started:

apt-get install zookeeperd

After the installation completes, ZooKeeper will be started as a daemon automatically. By default, it will listen on port 2181:

netstat -ant | grep :2181

Step 4. Installing Kafka Server.

First, download and extract Kafka from Apache website. You can use wget to download Kafka:

mkdir /opt/Kafka
cd /opt/Kafka
wget http://ftp.jaist.ac.jp/pub/apache/kafka/0.10.0.0/kafka_2.11-0.10.0.0.tgz

Extract the downloaded archive using tar command in /opt/Kafka:

tar -xvf kafka_2.11-0.10.0.0.tgz -C /opt/Kafka/

Configure Kafka Server:

sudo /opt/Kafka/kafka_2.11-0.10.0.0/bin/kafka-server-start.sh /opt/Kafka/kafka_2.11-0.10.0.0/config/server.properties

You can use nohup with script to start the Kafka server as a background process:

sudo nohup /opt/Kafka/kafka_2.11-0.10.0.0/bin/kafka-server-start.sh /opt/Kafka/kafka_2.11-0.10.0.0/config/server.properties /tmp/kafka.log 2>&1 &

Now, it is time to verify the Kafka server is operating correctly:

sudo /opt/Kafka/kafka_2.11-0.10.0.0/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testing

You should see the following output:

Created topic "testing".

Now, ask Zookeeper to list available topics on Apache Kafka:

sudo /opt/Kafka/kafka_2.11-0.10.0.0/bin/kafka-topics.sh --list --zookeeper localhost:2181

You should see the following output:

testing

Next, publish a sample messages to Apache Kafka topic called testing by using the following producer command:

sudo /opt/Kafka/kafka_2.11-0.10.0.0/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic testing

Finally, use consumer command to check for messages on Apache Kafka Topic called testing by running the following command:

sudo /opt/Kafka/kafka_2.11-0.10.0.0/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic testing --from-beginning

You should see the following output:

Hi how are you?
Where are you?

Well , you have successfully verified that you have a valid Apache Kafka setup with Apache Zookeeper.

Congratulation’s! You have successfully installed Apache Kafka. Thanks for using this tutorial for installing Apache Kafka on your Ubuntu 16.04 system. For additional help or useful information, we recommend you to check the official Apache Kafka web site.
