kafka配置

1.三节点主机环境：
#Red Hat Enterprise Linux Server release 7.5
192.168.154.128   my1.db.com   my1
192.168.154.129   my2.db.com   my2
192.168.154.130   my3.db.com   my3

2.配置jdk：
tar xvzf jdk-8u201-linux-x64.tar.gz
mv jdk1.8.0_201 /usr/local/jdk
vi .bash_profile
JAVA_HOME=/usr/local/jdk
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
source .bash_profile

3.下载zookeeper：
http://zookeeper.apache.org/releases.html
tar xvzf zookeeper-3.4.13.tar.gz
mv zookeeper-3.4.13 /usr/local/zookeeper

4.配置zookeeper：

编辑配置文件：
vi /usr/local/zookeeper/conf/zoo.cfg
tickTime=2000
dataDir=/usr/local/zookeeper/data
clientPort=2181
initLimit=5
syncLimit=2
dataLogDir=/usr/local/zookeeper/log
server.1=my1:2888:3888
server.2=my2:2888:3888
server.3=my3:2888:3888

创建目录：
mkdir -p /usr/local/zookeeper/data/
mkdir -p /usr/local/zookeeper/log/

echo 1 > /usr/local/zookeeper/data/myid
echo 2 > /usr/local/zookeeper/data/myid
echo 3 > /usr/local/zookeeper/data/myid

5.启动zookeeper：
/usr/local/zookeeper/bin/zkServer.sh start /usr/local/zookeeper/conf/zoo.cfg

查看状态：
/usr/local/zookeeper/bin/zkServer.sh status /usr/local/zookeeper/conf/zoo.cfg

6.下载kafka：
http://kafka.apache.org/downloads
tar xvzf kafka_2.12-2.0.0.tgz
mv kafka_2.12-2.0.0 /usr/local/kafka

mkdir -p /usr/local/kafka/data

编辑配置文件：
vi /usr/local/kafka/config/server.properties
broker.id=1
listeners=PLAINTEXT://my1:9092
zookeeper.connect=192.168.154.128:2181,192.168.154.129:2181,192.168.154.130:2181
delete.topic.enable=true

启动kafka：
/usr/local/kafka/bin/kafka-server-start.sh -daemon /usr/local/kafka/config/server.properties

查看确认：
jps

7.测试kafka：
创建一个测试topic：
/usr/local/kafka/bin/kafka-topics.sh –zookeeper 192.168.154.128:2181,192.168.154.129:2181,192.168.154.130:2181 –create –topic test-topic –partitions 3 –replication-factor 3
查看topic：
/usr/local/kafka/bin/kafka-topics.sh –zookeeper 192.168.154.128:2181,192.168.154.129:2181,192.168.154.130:2181 –list
/usr/local/kafka/bin/kafka-topics.sh –zookeeper 192.168.154.128:2181,192.168.154.129:2181,192.168.154.130:2181 –describe –topic test-topic

删除topic：
/usr/local/kafka/bin/kafka-topics.sh –zookeeper 192.168.154.128:2181,192.168.154.129:2181,192.168.154.130:2181 –delete –topic test-topic

producer发送消息：
/usr/local/kafka/bin/kafka-console-producer.sh –broker-list my1:9092,my2:9092,my3:9092 –topic test-topic

consumer消费消息：
/usr/local/kafka/bin/kafka-console-consumer.sh –bootstrap-server my1:9092,my2:9092,my3:9092 –topic test-topic –from-beginning

生产者吞吐量测试：
/usr/local/kafka/bin/kafka-producer-perf-test.sh –topic test-topic –num-records 500000 –record-size 200 –throughput -1 –producer-props bootstrap.servers=192.168.154.128:9092,192.168.154.129:9092,192.168.154.130:9092 acks=1
