I. Environmental configuration

1. System environment

[root@date ~] # cat / etc/centos-releaseCentOS Linux release 7.4.1708 (Core)

2.. Install the JAVA environment

Yum-y install java java-1.8.0-openjdk-devel#jps requires jdk-devel support

3. Download kafka

[root@slave1] # ls kafka_2.11-1.0.0.tgzkafka_2.11-1.0.0.tgz

2. Configure zookeeper

1. Modify the configuration file of zookeeper in kafka

[root@slave1 ~] # cat / opt/kafka/config/zookeeper.properties | grep-v "^ $" | grep-v "^ #" tickTime=2000initLimit=10syncLimit=5maxClientCnxns=300dataDir=/opt/zookeeper/datadataLogDir=/opt/zookeeper/logclientPort=2181server.1=20.0.5.11:2888:3888server.2=20.0.5.12:2888:3888server.3=20.0.5.13:2888:3888

two。 Copy the configuration file to another node

[root@slave1 ~] # pscp.pssh-h zlist / opt/kafka/config/zookeeper.properties / opt/kafka/config/ [root@slave1 ~] # cat zlist20.0.5.1120.0.5.1220.0.5.13

3. Create data and log directories on each node

[root@slave1 ~] # pssh-h zlist 'mkdir / opt/zookeeper/data' [root@slave1 ~] # pssh-h zlist' mkdir / opt/zookeeper/log'

4. Create a myid file

[root@slave1 ~] # pssh-H slave1-I 'echo 1 > / opt/zookeeper/data/myid' [root@slave1 ~] # pssh-H slave2-I' echo 2 > / opt/zookeeper/data/myid' [root@slave1 ~] # pssh-H slave3-I 'echo 3 > / opt/zookeeper/data/myid'

5. Start zookeeper

[root@slave1 ~] # pssh-h zlist 'nohup / opt/kafka/bin/zookeeper-server-start.sh / opt/kafka/config/zookeeper.properties &' [root@slave1 ~] # pssh-h zlist-I 'jps' [1] 23:29:36 [SUCCESS] 20.0.5.123492 QuorumPeerMain3898 Jps [2] 23:29:36 [SUCCESS] 20.0.5.117369 QuorumPeerMain9884 Jps [3] 23:29:36 [SUCCESS] 20.0.5.133490 QuorumPeerMain3898 Jps

3. Configure kafka

1. Modify server.properties

[root@slave1 ~] # cat / opt/kafka/config/server.propertiesbroker.id=1# machine uniquely identifies host.name=20.0.5.11# current broker machine ipport=9092#broker listening port number of threads num.network.threads=3# server accepts requests and response requests number of num.io.threads=8# IO threads socket.send.buffer.bytes=102400# send buffer size The data is first stored in the buffer and reaches a certain size after sending socket.receive.buffer.bytes=102400# to receive the buffer size, and after reaching a certain size, serialize to the disk the maximum number of log.dirs=/opt/kafkalog# message storage directories that socket.request.max.bytes=104857600# requests for messages to kafka or send messages to kafka. Delete.topic.enable=true# can delete the default number of partitions in topicnum.partitions=1# by command. A topic defaults to 1 partition num.recovery.threads.per.data.dir=1# sets the number of threads to recover and clean timeout data offsets.topic.replication.factor=3# is used to configure the number of partition copies of topic recorded by offset message save time log.segment.bytes=1073741824# log file maximum, log file greater than the maximum value Then create a new log.retention.check.interval.ms=300000# log retention check interval zookeeper.connect=20.0.5.11:2181,20.0.5.12:2181,20.0.5.13:2181#zookeeper address zookeeper.connection.timeout.ms=6000# connection zookeeper timeout

two。 Copy broke configuration files to other service nodes (modify broker.id and host.name)

3. Start kafka broke

[root@slave1 ~] # pssh-h zlist'/ opt/kafka/bin/kafka-server-start.sh / opt/kafka/config/server.properties > / root/kafka.log 2 > 1 pssh'[1] 02:13:05 [SUCCESS] 20.0.5.11 [2] 02:13:05 [SUCCESS] 20.0.5.12 [3] 02:13:05 [SUCCESS] 20.0.5.13 [root@slave1 ~] # pssh-h zlist-I 'jps' [1] 02 : 14:51 [SUCCESS] 20.0.5.123492 QuorumPeerMain6740 Jps6414 Kafka [2] 02:14:51 [SUCCESS] 20.0.5.133490 QuorumPeerMain4972 Kafka5293 Jps [3] 02:14:51 [SUCCESS] 20.0.5.117369 QuorumPeerMain11534 Kafka11870 Jps

4. Create topic

[root@slave1] # / opt/kafka/bin/kafka-topics.sh-- create-- zookeeper 20.0.5.11 zookeeper 2181 20.0.5.12 create 2181-- replication-factor 3-- partitions 3-- topic test1Created topic "test1". [root @ slave1 ~] # / opt/kafka/bin/kafka-topics.sh-- describe-- zookeeper 20.0.5.11 lance 2181 20.0.5.12 Lv 2181 20.0.5.13: 2181-topic test1Topic:test1 PartitionCount:3 ReplicationFactor:3 Configs: Topic:test1 Partition: 0 Leader: 2 Replicas: 2 1 Isr: 2,3,1 Topic: test1 Partition: 1 Leader: 3 Replicas: 3,1,2 Isr: 3,1,2 Topic: test1 Partition: 2 Leader: 1 Replicas: 1,2,3 Isr: 1,2,3

5. Start producer and consumer

[root@slave4] # / opt/kafka/bin/kafka-console-producer.sh-- broker-list 20.0.5.12 root@slave5 9092-- topic test1 [root@slave5] # / opt/kafka/bin/kafka-console-consumer.sh-- zookeeper 20.0.5.13 broker-list 2181-topic test1

6. Delete topic

[root@slave1] # / opt/kafka/bin/kafka-topics.sh-- delete-- zookeeper 20.0.5.11 zookeeper 2181-- topic test1Topic test1 is marked for deletion.Note: This will have no impact if delete.topic.enable is not set to true.
