Next is the kafka cluster setup:

6. You need to download scala, Kafka, and SLf4J. You are recommended to download the latest stable version from the official website

Scala: link: https://pan.baidu.com/s/1iavYH7w9EqyED57CMgQKkg extracted code: 8 s2h kafka: Link: https://pan.baidu.com/s/1SycMLCErwTlaiKl_uUpxQQ extracted code: 8 di2 slf4j: Link: https://pan.baidu.com/s/1OPs9fU9JdA2j8bZhhZHpYw extraction code: rxydCopy the code

Tar -zxvf scala-2.11.4. TGZ Rename the scala directory: mv scala-2.11.4 scala #3. Configure the Scala-related environment variable vi ~/.bashrc

export SCALA_HOME=/usr/local/scala
export PATH=$SCALA_HOME/bin
Copy the code

Source ~/.bashrc Check whether Scala is successfully installed: scala -version ## Follow the steps above to install Scala on all other machines. Copy Scala and.bashrc to the other two machines using SCP. Copy kafka to the /usr/local directory. TGZ: tar -zxvf kafka_2.9.2-0.8.1 TGZ Rename the kafka directory: mv kafka_2.9.2-0.8.1 kafka

Configuration kafka vim/usr/local/kafka/config/server properties

Broker. Id: growth in turn integer, 0, 1, 2, and the only id zookeeper broker in the cluster. The connect = 192.168.31.187:2181192168 31.19:2181192168 31.227:2181Copy the code

Install slf4j-nop-1.7.6.jar to kafka libs directory cp slf4j-nop-1.7.6.jar /usr/local/kafka/libs/

Solve the kafka Unrecognized VM option ‘UseCompressedOops’ problem

vim /usr/local/kafka/bin/kafka-run-class.sh

if [ -z "$KAFKA_JVM_PERFORMANCE_OPTS" ]; then
  KAFKA_JVM_PERFORMANCE_OPTS="-server  -XX:+UseCompressedOops -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSScavengeBeforeRemark -XX:+DisableExplicitGC -Djava.awt.headless=true"
fi
Copy the code

Drop -xx :+UseCompressedOops

#### Follow the steps above to install Kafka on the other two machines. Use SCP to copy Kafka to another machine. The only difference is that broker.id in server.properties is set to 1 and 2

In the kafka directory on the three machines, run the following commands: nohup bin/kafka-server-start.sh config/server.properties &

Use JPS to check whether the startup was successful

As a programmer, the ability to quickly set up environments and quickly test locally is essential.
