- 解压zk到指定的文件夹
tar zxvf zookeeper-3.4.5.tar.gz -C ../src/
- 修改zoo.cfg中日志文件存在内容
新建文件目录:/usr/local/app/tmp/zookeeper
dataDir=/usr/local/app/tmp/zookeeper
3.添加zk对应的环境变量~/.bashrc
export ZK_HOME=/usr/local/src/zookeeper-3.4.5
export PATH=$ZK_HOME/bin:$PATH
source一下,使环境变量生效: source ~/.bashrc
测试一下,echo $ZK_HOME
4.解压kafka到指定文件夹
tar zxvf kafka_2.11-0.10.2.1.tgz -C ../src/
5.配置环境变量
export KAFKA_HOME=/usr/local/src/kafka_2.11-0.10.2.1
export PATH=$KAFKA_HOME/bin:$PATH
source一下,source ~/.bashrc
echo一下, echo $KAFKA_HOME
6.修改kafka配置文件 $KAFKA_HOME/config/server.properties:
broker.id=0
listeners=PLAINTEXT://master:9092
log.dirs=/usr/local/app/tmp/kafka-logs
zookeeper.connect=master:2181
- 启动zk
zkServer.sh start $ZK_HOME/conf/zoo.cfg
查看启动状态:jps
[root@master bin]# jps
13094 Application
7636 Application
13432 Application
1711 SecondaryNameNode
16347 Jps
16330 QuorumPeerMain
1571 NameNode
查看运行的进程: jps -m
[root@master bin]# jps -m
13094 Application --conf-file /usr/local/src/apache-flume-1.6.0-bin/conf/exec_avro_console.conf --name a1
7636 Application --conf-file exec_hdfs.conf --name a1
13432 Application --conf-file /usr/local/src/apache-flume-1.6.0-bin/conf/exec_avro_console.conf --name a1
16359 Jps -m
1711 SecondaryNameNode
16330 QuorumPeerMain /usr/local/src/zookeeper-3.4.5/conf/zoo.cfg
1571 NameNode
8.启动kafka
kafka-server-start.sh $KAFKA_HOME/config/server.properties
执行jps查看启动状态;
执行jps -m查看正在运行的进程
- 创建topic
kafka-topics.sh --create --zookeeper master:2181 --replication-factor 1 --partitions 1 --topic hello_topic
查看zk上已注册的topic列表:
kafka-topics.sh --list --zookeeper master:2181
查看zk上所有topic的详细信息:
kafka-topics.sh --describe --zookeeper master:2181
# 查看指定topic的详细信息
kafka-topics.sh --describe --zookeeper master:2181 --topic hello_topic
10.发送消息:
kafka-console-producer.sh --broker-list master:9092 --topic hello_topic
11.消费消息
kafka-console-consumer.sh --bootstrap-server master:9092 --topic hello_topic --from-beginning
或
kafka-console-consumer.sh --zookeeper master:2181 --topic hello_topic --from-beginning
参数说明:
--from-beginning #表示从最开始消费消息
12.查看当前offset的值:
kafka-consumer-offset-checker.sh --zookeeper localhost:2181 --group group-1 --topic topic06
运行结果如下:
image.png
13.查询topic的offset的范围
用下面命令可以查询到topic:topic06 broker:localhost:9092的
offset的最小值：
kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list localhost:9092 —topic topic06 --time -2
查询offset的最大值：
kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list localhost:9092 —topic topic06 --time -1
从上面的输出可以看出topic:topic06有6个partition:0 offset范围分别为:
0 - [0,128]
1 - [0,131]
2 - [0,130]
3 - [0,128]
4 - [0,131]
5 - [0,131]
14.单节点多broker模式:
修改kafka的配置文件server.properties:
config/server-1.properties:
broker.id=1
listeners=PLAINTEXT://master:9093
log.dir=/usr/local/app/tmp/kafka-logs-1
config/server-2.properties:
broker.id=2
listeners=PLAINTEXT://:9094
log.dir=/usr/local/app/tmp/kafka-logs-2
启动多个kafka:
kafka-server-start.sh $KAFKA_HOME/config/server-1.properties &
kafka-server-start.sh $KAFKA_HOME/config/server-2.properties &
