安装
1.进入官网获取安装资源 http://kafka.apache.org/downloads
wget http://mirrors.tuna.tsinghua.edu.cn/apache/kafka/2.0.0/kafka_2.11-2.0.0.tgz
2.解压安装包
tar -zxvf kafka_2.11-2.0.0.tgz
修改配置文件
vim server.properties
相关注释:
broker.id=0 设置每一个节点的ID,且该ID属于唯一值
log.dirs=/tmp/kafka-logs 设置消息持久化目录
zookeeper.connect=192.168.16.139:2181 设置zookeeper链接地址,多个地址使用英文逗号分隔
listeners=PLAINTEXT://192.168.16.139:9092 服务器监听的地址,如果不配置从java.net.InetAddress.getCanonicalHostName()获得。在配置集群的时候,必须设置
注意:在集群的时候,broker.id和listeners不能相同
服务启停
1.启动。-daemon以守护进程方式启动kafka server
./bin/kafka-server-start.sh -daemon config/server.properties
启动后输入命令jps查看是否启动成功,若出现
说明启动成功
2.停止
./bin/kafka-server-stop.sh
3.附启动脚本
#!/bin/bash
#chkconfig:2345 20 90
#description:kafka
#processname:kafka
export JAVA_HOME=/soft/jdk1.8.0_201
case $1 in
start) /soft/kafka_2.11-2.0.0/bin/kafka-server-start.sh -daemon /soft/kafka_2.11-2.0.0/config/server.properties;;
stop) /soft/kafka_2.11-2.0.0/bin/kafka-server-stop.sh;;
status) /soft/jdk1.8.0_201/bin/jps;;
restart)
/soft/kafka_2.11-2.0.0/bin/kafka-server-stop.sh
/soft/kafka_2.11-2.0.0/bin/kafka-server-start.sh -daemon /soft/kafka_2.11-2.0.0/config/server.properties
;;
*) echo "require start|stop|status|restart" ;;
esac
消息收发
1.创建主题
./bin/kafka-topics.sh --create --zookeeper 192.168.16.139:2181 --replication-factor 1 --partitions 1 --topic test-topic
创建成功后可看到 Created topid "xxx"
2.查看主题/消息
./bin/kafka-topics.sh --list --zookeeper 192.168.16.139:2181
./bin/kafka-topics.sh --describe --zookeeper 192.168.16.139:2181 --topic test-topic
3.删除主题
./bin/kafka-topics.sh --delete --zookeeper 192.168.16.139:2181 --topic test-topic
3.发送主题消息
./bin/kafka-console-producer.sh --broker-list 192.168.16.139:9092 --topic test-topic
4.消费主题消息
./bin/kafka-console-consumer.sh --bootstrap-server 192.168.16.139:9092 --topic test-topic --from-beginning --partition 0
监控插件 kafka eagle
1.安装包下载 http://download.smartloli.org/
2.将下载好的安装包上传至服务器,然后使用 tar -zxvf kafka-eagle-bin-1.3.0.tar.gz 进行解压。解压后,会得到另外一个压缩包,继续将其加压。
3.修改环境变量,增加 JAVA_HONE 和 KE_HOME
vim /etc/profile
#kafka-eagle-web-1.3.0
export KE_HOME=/soft/kafka-eagle-web-1.3.0
export PATH=$PATH:$KE_HOME/bin
source /etc/profile
4.修改 kafka-eagle 配置文件
vim conf/system-config.properties
kafka.eagle.zk.cluster.alias=cluster1
cluster1.zk.list=192.168.16.139:2181
kafka.eagle.webui.port=8048
kafka.eagle.metrics.charts=true
kafka.eagle.sql.fix.error=true
kafka.eagle.driver=com.mysql.jdbc.Driver
kafka.eagle.url=jdbc:mysql://127.0.0.1:3306/kafka?useSSL=true&characterEncoding=utf8&useUnicode=true&serverTimezone=UTC
kafka.eagle.username=username
kafka.eagle.password=password
5.保存退出后,为启动文件授权 chmod +x bin/ke.sh
6.启停 ./bin/ke.sh start [ ./bin/ke.sh stop]
7.附开机自启动相关命令与脚本
vim /etc/init.d/kafka-eagle
#!/bin/bash
#chkconfig:2345 80 20
#description:kafka-eagle
case $1 in
start) /soft/kafka-eagle-web-1.3.0/bin/ke.sh start ;;
stop) /soft/kafka-eagle-web-1.3.0/bin/ke.sh stop ;;
status) /soft/kafka-eagle-web-1.3.0/bin/ke.sh status ;;
restart) /soft/kafka-eagle-web-1.3.0/bin/ke.sh restart ;;
*) echo "require start|stop|status|restart" ;;
esac
chmod +x kafka-eagle
chkconfig --add /etc/init.d/kafka-eagle
