kafka zookeeper配置初步

1.軟件需求

CentOS 7.2 X64

jdk-8u121-linux-x64.rpm

zookeeper-3.4.9.tar.gz

kafka_2.11-0.10.1.0.tgz

setuptools-33.1.1.zip 

kafka-python-1.3.2.tar.gz

2.安裝zookeeper、kafka

1).zookeeper

# tar -zxf zookeeper-3.4.9.tar.gz

# mv zookeeper-3.4.9 /usr/local/zookeeper

# mkdir -p /var/lib/zookeeper

# cat > /usr/local/zookeeper/conf/zoo.cfg << EOF

tickTime=2000

dataDir=/var/lib/zookeeper

clientPort=2181

EOF

# /usr/local/zookeeper/bin/zkServer.sh start

ZooKeeper JMX enabled by default

Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

#

2).kafka

# tar -zxf kafka_2.11-0.10.1.0.tgz

# mv kafka_2.11-0.10.1.0 /usr/local/kafka

# mkdir /tmp/kafka-logs

# /usr/local/kafka/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic telematics

fCreated topic "telematics".

#

3.create topics

# /usr/local/kafka/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic telematics

4.topic操作

1).list topic

# /usr/local/kafka/bin/kafka-topics.sh --zookeeper localhost:2181 --list

telematics

2).describe topic

# /usr/local/kafka/bin/kafka-topics.sh --zookeeper localhost:2181 --describe --topic telematics

Topic:telematics        PartitionCount:1        ReplicationFactor:1     Configs:

        Topic: telematics       Partition: 0    Leader: 0       Replicas: 0     Isr: 0

#

3).delete topic

#/usr/local/kafka/bin/kafka-topics.sh --zookeeper localhost:2181 --delete --topic telematics

5.添加選項執行刪除命令時生效，否則只是標記為刪除

/usr/local/kafka/config/server.properties

delete.topic.enable=true

6.測試腳本

1). producer.py 

#!/usr/bin/python

from kafka import KafkaProducer

producer = KafkaProducer(bootstrap_servers='192.168.1.201:9092')

producer = KafkaProducer(key_serializer=str.encode, value_serializer=str.encode)

producer.send('telematics', key='ping', value=b'1234')

# 

2). consumer.py

from kafka import KafkaConsumer

# To consume latest messages and auto-commit offsets

consumer = KafkaConsumer('telematics',bootstrap_servers=['192.168.1.201:9092'])

for message in consumer:

    # message value and key are raw bytes -- decode if necessary!

    # e.g., for unicode: `message.value.decode('utf-8')`

    print ("%s:%d:%d: key=%s value=%s" % (message.topic, message.partition,

                                          message.offset, message.key,

                                          message.value))

#
