准备三台机器
172.17.0.2
172.17.0.12
172.17.0.13
1.下载kafka安装包
第一步安装kafka
mkdir /data
cd /data
wget https://mirrors.tuna.tsinghua.edu.cn/apache/kafka/2.4.1/kafka_2.12-2.4.1.tgz
新版kafka都自带zookeeper
tar xf kafka_2.12-2.4.1.tgz
mv kafka_2.12-2.4.1 kafka
第二步:zk配置文件，三台一样
cd kafka
egrep -v "(^#|^$)" config/zookeeper.properties
dataDir=/data/kafka/zookeeper_data
tickTime=2000
initLimit=10
syncLimit=5
clientPort=2181
maxClientCnxns=0
admin.enableServer=false
server.1=172.17.0.2:2888:3888
server.2=172.17.0.12:2888:3888
server.3=172.17.0.13:2888:3888
第三步:创建myid文件
cd
cd ..
cd /data/kafka/zookeeper_data
vim myid
分别设置成1,2,3
第四步：启动zk
cd ..
cd bin/
./zookeeper-server-start.sh -daemon ../config/zookeeper.properties
这样zk集群就搭建成功了,记得防火墙开启 TCP:2181,2888,3888,9095
第五步：搭建kafka集群,每一个的broker.id要不一样,listeners要是本机ip
cd ..
egrep -v "(^#|^$)" config/server.properties
broker.id=0
listeners=SASL_PLAINTEXT://172.17.0.2:9095
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.enabled.mechanisms=PLAIN
sasl.mechanism.inter.broker.protocol=PLAIN
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/tmp/kafka-logs
num.partitions=1
num.recovery.threads.per.data.dir=1
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=172.17.0.2:2181,172.17.0.12:2181,172.17.0.13:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
第六步：创建 kafka_server_jaas.conf,3台主机都要添加
vim config/kafka_server_jaas.conf
KafkaServer {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="kafka" password="kafkapswd"
user_kafka="kafkapswd" user_mooc="moocpswd";
};
第七步：创建 kafka_client_jaas.conf,3台主机都要添加
vim kafka_client_jaas.conf
KafkaClient {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="mooc"
password="moocpswd";
};
第八步:在bin/kafka-server-start.sh添加,3台主机都要添加
if [ "x$KAFKA_OPTS" ]; then
export KAFKA_OPTS="-Djava.security.auth.login.config=/data/kafka/config/kafka_server_jaas.conf"
fi
第九步:在kafka-console-producer.sh 和 kafka-console-consumer.sh 文件添加,3台主机都要添加
if [ "x$KAFKA_OPTS" ]; then
export KAFKA_OPTS="-Djava.security.auth.login.config=/data/kafka/config/kafka_client_jaas.conf"
fi
cd bin/
./kafka-server-start.sh -daemon ../config/server.properties
都是三台机器操作 kafka集群也搭建成功了
bin/kafka-topics.sh --create --zookeeper 172.17.0.2:2181,172.17.0.12:2181,172.17.0.13:2181 --replication-factor 3 --partitions 3 --topic topicTest
#集群中查看topic
bin/kafka-topics.sh --list --zookeeper 172.17.0.2:2181,172.17.0.12:2181,172.17.0.13:2181
#生产者
bin/kafka-console-producer.sh --broker-list 172.17.0.2:9095,172.17.0.12:9095,172.17.0.13:9095 --topic topicTest --producer-property security.protocol=SASL_PLAINTEXT --producer-property sasl.mechanism=PLAIN
#消费者
bin/kafka-console-consumer.sh --bootstrap-server 172.17.0.2:9095,172.17.0.12:9095,172.17.0.13:9095 --topic topicTest --consumer-property security.protocol=SASL_PLAINTEXT --consumer-property sasl.mechanism=PLAIN --from-beginning
