获取压缩包&解压
mkdir -p /data/kafka && cd /data/kafka
wget https://downloads.apache.org/kafka/2.7.0/kafka_2.12-2.7.0.tgz
tar -zxvf kafka_2.12-2.7.0.tgz
修改配置文件
通用修改
sed -i s#log.dirs=/tmp/kafka-logs#log.dirs=/data/kafka/logs#g /data/kafka/kafka_2.12-2.7.0/config/server.properties
sed -i s#zookeeper.connect=localhost:2181#zookeeper.connect=192.168.199.104:2181,192.168.199.105:2181,192.168.199.106:2181#g /data/kafka/kafka_2.12-2.7.0/config/server.properties
分节点修改
sed -i s#broker.id=0#log.dirs=broker.id=0#g /data/kafka/kafka_2.12-2.7.0/config/server.properties
echo "listeners=PLAINTEXT://192.168.199.101:9092" >> /data/kafka/kafka_2.12-2.7.0/config/server.properties
后台启动kafka
cd /data/kafka/kafka_2.12-2.7.0
bin/kafka-server-start.sh -daemon config/server.properties

看到这些说明启动成功了
测试验证
1、创建Topic
在yfm01(Broker)上创建测试Tpoic：test-yfm01，这里我们指定了3个副本、1个分区
[root@yfm01 kafka_2.12-2.7.0]# bin/kafka-topics.sh --create --bootstrap-server 192.168.199.101:9092 --replication-factor 3 --partitions 1 --topic test-yfm01
2、查看Topic
[root@yfm02 kafka_2.12-2.7.0]# bin/kafka-topics.sh --list --bootstrap-server 192.168.199.102:9092
test-yfm01
3、发送消息
这里我们向Broker(id=0)的Topic=test-yfm01发送消息
[root@yfm01 kafka_2.12-2.7.0]# bin/kafka-console-producer.sh --broker-list 192.168.199.101:9092 --topic test-yfm01
>test by yfm
4、消费消息
在yfm02上消费Broker03的消息
bin/kafka-console-consumer.sh --bootstrap-server 192.168.199.103:9092 --topic test-yfm01 --from-beginning
在yfm03上消费Broker02的消息
bin/kafka-console-consumer.sh --bootstrap-server 192.168.199.102:9092 --topic test-yfm01 --from-beginning
均能收到消息，这是因为这两个消费消息的命令是建立了两个不同的Consumer
如果我们启动Consumer指定Consumer Group Id就可以作为一个消费组协同工，1个消息同时只会被一个Consumer消费到
bin/kafka-console-consumer.sh --bootstrap-server 192.168.199.103:9092 --topic test-yfm01 --from-beginning --group testgroup_ken
bin/kafka-console-consumer.sh --bootstrap-server 192.168.199.102:9092 --topic test-yfm01 --from-beginning --group testgroup_ken
关闭kafka
bin/kafka-server-stop.sh
Instalar cmak
Requerimientos de instalación:
- Admite Kafka 0.8 y superior
- Java 11+
- Zookeeper debe ser de la versión 3.5+.
添加jdk11用户并授权
[root@yfm01 cmak-3.0.0.5]# adduser jdk11
[root@yfm01 cmak-3.0.0.5]# passwd jdk11
jdk11
授权sudo权限
chmod -v u+w /etc/sudoers
vim /etc/sudoers
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
jdk11 ALL=(ALL) ALL
使用jdk11账户登录
下载jdk11到本地/data/jdk11,我这里下载的是jdk-11.0.10_linux-x64_bin.tar.gz
tar -zxvf jdk-11.0.10_linux-x64_bin.tar.gz
vi ~/.bashrc
添加下面四行
export JAVA_HOME=/data/jdk11/jdk-11.0.10
export JRE_HOME=$JAVA_HOME/jre
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=./:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
source ~/.bashrc
在192.168.199.101,yfm01上安装kafka可视化管理工具cmak
获取安装包
mkdir -p /data/cmak && cd /data/cmak
wget https://github.com/yahoo/CMAK/releases/download/3.0.0.5/cmak-3.0.0.5.zip
安装unzip
yum install -y unzip zip
unzip cmak-3.0.0.5.zip && cd cmak-3.0.0.5
修改配置文件
vi conf/application.conf
将下面的两个配置项配置成你实际的kafka集群对应的zookeeper地址。
kafka-manager.zkhosts="192.168.199.104:2181,192.168.199.105:2181,192.168.199.106:2181"
cmak.zkhosts="192.168.199.104:2181,192.168.199.105:2181,192.168.199.106:2181"
修改用户组
sudo chown -R jdk11:jdk11 cmak-3.0.0.5/
启动服务
nohup bin/cmak -Dconfig.file=conf/application.conf -Dhttp.port=9001 >kafka-manager.log 2>&1 &
cmak配置
新建cluster，即可
停止服务
kill pid
