我对Kafka完全陌生,我很难把它弄对。
我使用docker compose为docker设置了以下“wurstmeister/kafka docker”:
zookeeper:
image: wurstmeister/zookeeper
ports:
- "2181:2181"
kafka:
image: wurstmeister/kafka
ports:
- "9092:9092"
links:
- zookeeper:zk
environment:
KAFKA_ADVERTISED_HOST_NAME: 192.168.59.103
# KAFKA_AUTO_CREATE_TOPCIS_ENABLE: 'true'
KAFKA_CREATE_TOPICS: "events:1:1"
volumes:
- /var/run/docker.sock:/var/run/docker.sock
作为生产者和消费者,我使用的是ruby gem“kafka rb”。
制作人:
require 'kafka'
producer = Kafka::Producer.new({
host: "192.168.59.103",
port: 9092,
topic: "events"
})
1000000.times do |i|
message = Kafka::Message.new("Message #{i}")
producer.push(message)
end
消费者:
需要“Kafka”
consumer = Kafka::Consumer.new({
host: "192.168.59.103",
port: 9092,
topic: "events"
})
consumer.loop do |messages|
puts "Received"
puts messages
end
但我仍然收到拒绝连接或错误:

设置有什么根本性的问题吗?谢谢您

按热度按时间rbl8hiat1#
这个错误是什么时候发生的
wurstmeister/zookeeper
当你试图产生或消费信息时。为什么要报道
Closing socket for /192.168.59.3
,应该是吗192.168.59.103
,您是否可以尝试ping或telnet kafka服务器在您运行生产者和消费者的地方,看看您是否可以连接到它。
