一、环境配置
1.系统环境
[root@date ~]# cat /etc/centos-release CentOS Linux release 7.4.1708 (Core)2..安装JAVA环境
yum -y install java java-1.8.0-openjdk-devel #jps需要jdk-devel支持3.下载kafka
[root@slave1 ~]# ls kafka_2.11-1.0.0.tgz kafka_2.11-1.0.0.tgz二、配置zookeeper
1.修改kafka中zookeeper的配置文件
[root@slave1 ~]# cat /opt/kafka/config/zookeeper.properties | grep -v "^$" | grep -v "^#" tickTime=2000 initLimit=10 syncLimit=5 maxClientCnxns=300 dataDir=/opt/zookeeper/data dataLogDir=/opt/zookeeper/log clientPort=2181 server.1=20.0.5.11:2888:3888 server.2=20.0.5.12:2888:3888 server.3=20.0.5.13:2888:38882.复制配置文件到其他节点
[root@slave1 ~]# pscp.pssh -h zlist /opt/kafka/config/zookeeper.properties /opt/kafka/config/ [root@slave1 ~]# cat zlist 20.0.5.11 20.0.5.12 20.0.5.133.在各个节点创建数据和日志目录
[root@slave1 ~]# pssh -h zlist 'mkdir /opt/zookeeper/data' [root@slave1 ~]# pssh -h zlist 'mkdir /opt/zookeeper/log'4.创建myid文件
[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.启动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] 20.0.5.12 3492 QuorumPeerMain 3898 Jps [2] 23:29:36 [SUCCESS] 20.0.5.11 7369 QuorumPeerMain 9884 Jps [3] 23:29:36 [SUCCESS] 20.0.5.13 3490 QuorumPeerMain 3898 Jps三、配置kafka
1.修改server.properties
[root@slave1 ~]# cat /opt/kafka/config/server.properties broker.id=1 #机器唯一标识 host.name=20.0.5.11 #当前broker机器ip port=9092 #broker监听端口 num.network.threads=3 #服务器接受请求和响应请求的线程数 num.io.threads=8 #io线程数 socket.send.buffer.bytes=102400 #发送缓冲区大小，数据先存储到缓冲区了到达一定的大小后在发送 socket.receive.buffer.bytes=102400 #接收缓冲区大小,达到一定大小后序列化到磁盘 socket.request.max.bytes=104857600 #向kafka请求消息或者向kafka发送消息的请求的大数 log.dirs=/opt/kafkalog #消息存放目录 delete.topic.enable=true #能够通过命令删除topic num.partitions=1 #默认的分区数，一个topic默认1个分区数 num.recovery.threads.per.data.dir=1 #设置恢复和清理超时数据的线程数量 offsets.topic.replication.factor=3 #用于配置offset记录的topic的partition的副本个数 transaction.state.log.replication.factor=3 transaction.state.log.min.isr=3 log.retention.hours=168 #消息保存时间 log.segment.bytes=1073741824 #日志文件大值，当日志文件的大于大值，则创建一个新的 log.retention.check.interval.ms=300000 #日志保留检查间隔 zookeeper.connect=20.0.5.11:2181,20.0.5.12:2181,20.0.5.13:2181 #zookeeper地址 zookeeper.connection.timeout.ms=6000 #连接zookeeper超时时间2.复制broke配置文件到其他服务节点上（修改broker.id和host.name）
3.启动kafka broke
[root@slave1 ~]# pssh -h zlist '/opt/kafka/bin/kafka-server-start.sh /opt/kafka/config/server.properties > /root/kafka.log 2>1&' [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] 20.0.5.12 3492 QuorumPeerMain 6740 Jps 6414 Kafka [2] 02:14:51 [SUCCESS] 20.0.5.13 3490 QuorumPeerMain 4972 Kafka 5293 Jps [3] 02:14:51 [SUCCESS] 20.0.5.11 7369 QuorumPeerMain 11534 Kafka 11870 Jps4.创建topic
[root@slave1 ~]# /opt/kafka/bin/kafka-topics.sh --create --zookeeper 20.0.5.11:2181,20.0.5.12:2181,20.0.5.13:2181 --replication-factor 3 --partitions 3 --topic test1 Created topic "test1". [root@slave1 ~]# /opt/kafka/bin/kafka-topics.sh --describe --zookeeper 20.0.5.11:2181,20.0.5.12:2181,20.0.5.13:2181 --topic test1 Topic:test1 PartitionCount:3 ReplicationFactor:3 Configs: Topic: test1 Partition: 0 Leader: 2 Replicas: 2,3,1 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: 1,2,35.启动producer和consumer
[root@slave4 ~]# /opt/kafka/bin/kafka-console-producer.sh --broker-list 20.0.5.12:9092 --topic test1 [root@slave5 ~]# /opt/kafka/bin/kafka-console-consumer.sh --zookeeper 20.0.5.13:2181 --topic test1
6.删除topic
[root@slave1 ~]# /opt/kafka/bin/kafka-topics.sh --delete --zookeeper 20.0.5.11:2181 --topic test1 Topic test1 is marked for deletion. Note: This will have no impact if delete.topic.enable is not set to true.另外有需要云服务器可以了解下创新互联cdcxhl.cn，海内外云服务器15元起步，三天无理由+7*72小时售后在线，公司持有idc许可证，提供“云服务器、裸金属服务器、高防服务器、香港服务器、美国服务器、虚拟主机、免备案服务器”等云主机租用服务以及企业上云的综合解决方案，具有“安全稳定、简单易用、服务可用性高、性价比高”等特点与优势，专为企业上云打造定制，能够满足用户丰富、多元化的应用场景需求。
