(in construction)

Requirements

• zookeeper >= 3.4.10
• java >= 1.8
• maven >= 3.7.0

Tested with ubuntu 16.04

How to use it

Two different ways

Building an image with docker and executed afterwards

1. Move to the folder where the repo is placed: i.e.: cd ZookeeperMessaging
2. Build the image with docker, be careful with the name (zookeepermessaging). The command should be similar to: sudo docker build -t zookeepermessaging .
3. Execute the script zkapp.sh ./zkapp.sh

• The script will start docker, mount the folder in /home/dev, and will start the script inside-container.sh

4. Access with the browser to the following url: localhost:8080

With everything installed on the system (linux)

1. Download/clone/fork repository and move inside the folder.
2. Compile project with maven mvn clean install
3. Launch zookeeper server: i.e. /opt/zookeeper-3.4.9/bin/zkServer.sh start
4. Launch kafka server: i.e. /opt/kafka_2.12-1.0.0/bin/kafka-server-start.sh /opt/kafka_2.12-1.0.0/config/server.properties
5. Launch master program: i.e. mvn exec:java -Dexec.mainClass="com.company.Master"
6. Two different modes:
   1. ZooKeeper Only => Launch workerfactory: i-e. mvn exec:java -Dexec.mainClass="websocket.WorkerFactory"
   2. Zookeeper + Kafka streaming => Launch kafkaworkerfactory: i.e. mvn exec:java -Dexec.mainClass="websocket.KafkaWorkerFactory"
7. Launch onlineuserkeepalive: i.e. mvn exec:java -Dexec.mainClass="websocket.OnlineUserKeepAlive"
8. Access with your favorite browser to the file index.html located in src/main/java/websocket/index.html
   • i.e. firefox src/main/java/websocket/index.html
