1.安装kafka环境

# 看这个地址
https://blog.csdn.net/github_38482082/article/details/82112641
# 你还需要装Java环境
# 测试启动如果启动成功，那么证明kafka启动成功
.\bin\windows\zookeeper-server-start.bat  .\config\zookeeper.properties
#启动kafka
.\bin\windows\kafka-server-start.bat .\config\server.properties

# 创建top
.\bin\windows\kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
# 生产者
.\bin\windows\kafka-console-producer.bat --broker-list localhost:9092 --topic test
# 消费者
.\bin\windows\kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic test --from-beginning

 2.pykafka

　　2,1安装

　　pip install pykafka

　　2.2生产者

from pykafka import KafkaClient
from conf import KAFKA_HOSTS_LOCALHOST
#连接kafka客户端
kafka_client = KafkaClient(hosts=KAFKA_HOSTS_LOCALHOST)
#获取topic
topic = kafka_client.topics["test"]
#获取生产者对象
produce = topic.get_producer()
#传数据必须是字节
produce.produce("now_time_bytes".encode("utf8"))
#手动关闭该生产者
produce.stop()

　　2.3消费者

# 导入安装包
from pykafka import KafkaClient
# 设置客户端的连接信息
client = KafkaClient(hosts="127.0.0.1:9092")
topic = client.topics['test']
# print(client.topics)
# print(topic.latest_available_offsets())
#consumer_group 与consumer_id值不能一样，不同group相互独立
consumer  = topic.get_simple_consumer(
    consumer_group='18',
    auto_commit_enable=True,
    auto_commit_interval_ms=1,
    reset_offset_on_start=True
    # consumer_id =1,
)


for message in consumer:
    if message is not None:
        print(message.offset, message.value)
