kafka集群原理

kafka学习使用中涉及许多原理,了解这些原理会让学习事半功倍。

一、专业术语

kafka cluster是分布式消息传递系统,与MQ cluster(消息队列)类似,由broker list(kafka运行的节点)和多个topic(主题)组成,在Kafka中,每个topic被细分为多个partition,而每个partition又可以被副本到多个kafka broker上实现高可用性。因此,kafka cluster是由多个broker节点和多个topic partition组成的。

producer是生产者角色,主要负责生产数据,是向kafka cluster写入数据的一方,数据的写入有两种常见策略,要么是rr算法,要么是基于key的hash值和分区数取余。

consumer是消费者角色,主要是负责消费数据,是从kafka cluster拉取数据的一方。

topic是主题,是数据存储的逻辑单元。

replica是副本,实际存储数据的地方,一个topic最少要有一个副本。

partition是分区,一个topic最少要有一个分区,正常情况下有多个分区编号的。副本是分区的实际载体。

consumer group是消费者组,一个消费者组里面最少有一个消费者,同一个消费者组的消费者不能同时消费同一个topic的partition,以免造成数据重复消费;当一个消费者组的消费者数据发生变化时,会触发rebalance(重平衡)机制,即重新分配分区消费。

ISR是和leader数据同步的所有副本集合

OSR是和leader数据不同步的所有副本集合

AR是ISR和OSR的集合,就是所有的副本集合

二、为什么kafka会丢数据

假如30秒内leader和follower数据的LEO(Log End Offset)一致,则认为数据一致,当follower的数据还没有与leader完全同步时,leader节点宕机了,此时,follower选举出新的leader,其他的follower会跟随这个leader数据继续工作,如果之前leader恢复了,会从之前的HW(高水位线,ISR中最后一个副本最小的LEO)开始重新写数据,与新的leader同步,之前follower没同步的就丢失了,若30秒内,副本没有和leader的LEO相同,会直接踢出ISR,进入OSR列表。

kafka集群基本使用

一、启动kafka

1、先启动zookeeper

[root@ELK103 ~]# manager_zk.sh start
启动服务
========== elk101 zkServer.sh start ================
Starting zookeeper ... STARTED
========== elk102 zkServer.sh start ================
Starting zookeeper ... STARTED
========== elk103 zkServer.sh start ================
Starting zookeeper ... STARTED
[root@ELK103 ~]# manager_zk.sh status
查看状态
========== elk101 zkServer.sh status ================
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: follower
========== elk102 zkServer.sh status ================
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: leader
========== elk103 zkServer.sh status ================
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: follower

2、模仿zookeeper启动脚本写一个kafka启动脚本,并给予执行权限

[root@ELK101 ~]# cat /usr/local/sbin/manager_kafka.sh
#!/bin/bash

#判断用户是否传参
if [ $# -ne 1 ];then
    echo "无效参数,用法为: $0  {start|stop|restart|status}"
    exit
fi

#获取用户输入的命令
cmd=$1

#定义函数功能
function kafkaManger(){
    case $cmd in
    start)
        echo "启动服务"        
        remoteExecution start
        ;;
    stop)
        echo "停止服务"
        stopKafka stop
        ;;
    restart)
        echo "重启服务"
        remoteExecution restart
        ;;
    status)
        echo "查看状态"
        remoteExecution status
        ;;
    *)
        echo "无效参数,用法为: $0  {start|stop|restart|status}"
        ;;
    esac
}


#定义执行的命令
function remoteExecution(){
    for (( i=101 ; i<=103 ; i++ )) ; do
            tput setaf 2
            echo ========== elk${i} kafaka-server-start.sh   $1 ================
            tput setaf 9
            ssh elk${i} "kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties" 
    done
}

function stopKafka(){
    for (( i=101 ; i<=103 ; i++ )) ; do
            tput setaf 2
            echo ========== elk${i} kafaka-server-stop.sh   $1 ================
            tput setaf 9
            ssh elk${i} "kafka-server-stop.sh -daemon $KAFKA_HOME/config/server.properties" 
    done

}


#调用函数
kafkaManger
[root@ELK101 ~]# chmod +x /usr/local/sbin/manager_kafka.sh
[root@ELK101 ~]# ll /usr/local/sbin/manager_kafka.sh
-rwxr-xr-x 1 root root 1323 Jun  5 11:29 /usr/local/sbin/manager_kafka.sh

3、通过启动脚本启动kafka

[root@ELK101 ~]# manager_kafka.sh start
启动服务
========== elk101 kafaka-server-start.sh start ================
========== elk102 kafaka-server-start.sh start ================
========== elk103 kafaka-server-start.sh start ================

二、topic管理

1、增

[root@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --create --topic koten
Created topic koten.      #创建一个名为koten的topic

[root@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --create --topic koten-3 --partitions 3
Created topic koten-3.    #创建一个名为koten-3的topic,分区数为3

[root@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --create --topic koten-3-2 --partitions 3 --replication-factor 2
Created topic koten-3-2.  #创建一个名为koten-3-2的topic,分区数为3,副本数为2

2、查

#查看topic列表
[root@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --list
koten
koten-3
koten-3-2

#查看所有topic的详细信息
[root@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --describe
Topic: koten-3-2	TopicId: 1l4P-Tv_Q3aTasKediU3MQ	PartitionCount: 3	ReplicationFactor: 2   Configs: segment.bytes=1073741824
	Topic: koten-3-2	Partition: 0	Leader: 103	Replicas: 103,102	Isr: 103
	Topic: koten-3-2	Partition: 1	Leader: 102	Replicas: 102,101	Isr: 102,101
	Topic: koten-3-2	Partition: 2	Leader: 101	Replicas: 101,103	Isr: 101,103
Topic: koten	TopicId: eXxgjWBySxe_WAx-fv83ZA	PartitionCount: 1	ReplicationFactor: 1	Configs: segment.bytes=1073741824
	Topic: koten	Partition: 0	Leader: 103	Replicas: 103	Isr: 103
Topic: koten-3	TopicId: l7L3SY63QV-ayXOD46bViQ	PartitionCount: 3	ReplicationFactor: 1	Configs: segment.bytes=1073741824
	Topic: koten-3	Partition: 0	Leader: 103	Replicas: 103	Isr: 103
	Topic: koten-3	Partition: 1	Leader: 102	Replicas: 102	Isr: 102
	Topic: koten-3	Partition: 2	Leader: 101	Replicas: 101	Isr: 101

#查看指定topic的详细信息
oot@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --describe --topic koten
Topic: koten	TopicId: eXxgjWBySxe_WAx-fv83ZA	PartitionCount: 1	ReplicationFactor: 1	Configs: segment.bytes=1073741824
	Topic: koten	Partition: 0	Leader: 103   Replicas: 103	Isr: 103

3、改

主分片数可以用命令行直接修改,副本数修改比较麻烦,需要用json格式,可以参考这个大神的链接:

#修改koten的topic分区为5个
[root@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --alter --topic koten --partitions 5

4、删

[root@ELK101 ~]# kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --delete --topic koten

三、生产者和消费者

1、启动生产者

[root@ELK101 ~]# kafka-console-producer.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic koten-3

2、启动消费者(在同一主机)

表示从最新的offset拉取数据

[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.102:9092 --topic koten-3

表示从头开始拉取数据

[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.102:9092 --topic koten-3 --from-beginning

四、消费者组管理

1、查看现有的消费者组

[root@ELK101 ~]# kafka-consumer-groups.sh --bootstraerver  10.0.0.101:9092 --list
console-consumer-24702
console-consumer-58734
console-consumer-41114

2、列出所有消费者组的详细信息,包括偏移量,消费者ID,LEO等信息

[root@ELK101 ~]# kafka-consumer-groups.sh --bootstrap-server  10.0.0.101:9092 --describe --all-groups 

Consumer group 'console-consumer-24702' has no active members.

Consumer group 'console-consumer-41114' has no active members.

GROUP                  TOPIC           PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG             CONSUMER-ID                                           HOST            CLIENT-ID
console-consumer-58734 koten-3         0          -               1               -               console-consumer-f92294eb-383c-402b-9f9e-9a7ac5773b7d /10.0.0.101     console-consumer
console-consumer-58734 koten-3         1          -               2               -               console-consumer-f92294eb-383c-402b-9f9e-9a7ac5773b7d /10.0.0.101     console-consumer
console-consumer-58734 koten-3         2          -               3               -               console-consumer-f92294eb-383c-402b-9f9e-9a7ac5773b7d /10.0.0.101     console-consumer

3、查看内置topic的offset数据,了解即可,我这边运行没有显示内容

[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic __consumer_offsets --formatter "kafka.coordinator.group.GroupMetadataManager\$OffsetsMessageFormatter"   --from-beginning

4、基于配置文件指定消费组

[root@ELK101 ~]# cat $KAFKA_HOME/config/consumer.properties
......
group.id=koten-consumer-group
......
[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.101:9092 --topic koten-topic --consumer.config $KAFKA_HOME/config/consumer.properties
[2023-06-05 20:25:33,829] WARN [Consumer clientId=console-consumer, groupId=koten-consumer-group] Error while fetching metadata with correlation id 2 : {koten-topic=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

5、基于命令行参数指定消费者组

[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.101:9092 --topic koten-topic --consumer-property group.id=koten-consumer-group

zookeeper堆内存调优

生产环境建议调到2G~4G

1、查zookeeper的堆内存大小

[root@ELK101 ~]#  jmap -heap `jps | awk '/QuorumPeerMain/{print $1}'` | grep MaxHeapSize
   MaxHeapSize              = 1048576000 (1000.0MB)
[root@ELK101 ~]#

2、修改堆内存的大小

[root@ELK101 ~]# cat > /koten/softwares/apache-zookeeper-3.8.1-bin/conf/java.env <<'EOF'
#!/bin/bash
# 指定JDK的按住路径
export JAVA_HOME=/koten/softwares/jdk1.8.0_291

# 指定zookeeper的堆内存大小
export JVMFLAGS="-Xms128m -Xmx128m $JVMFLAGS"
EOF

3、将配置文件同步到集群的其他zk节点上

[root@ELK101 ~]# data_rsync.sh /koten/softwares/apache-zookeeper-3.8.1-bin/conf/java.env 
===== rsyncing elk102: java.env =====
命令执行成功!
===== rsyncing elk103: java.env =====
命令执行成功!

4、重启zk集群,注意一定要重启后堆内存才生效,manager_zk脚本不好用,有时候停止了,进程还存在,需要手动挨个运行zkServer.sh stop

[root@ELK101 ~]# manager_zk.sh restart
重启服务
========== elk101 zkServer.sh restart ================
Stopping zookeeper ... STOPPED
Starting zookeeper ... STARTED
========== elk102 zkServer.sh restart ================
Stopping zookeeper ... STOPPED
Starting zookeeper ... STARTED
========== elk103 zkServer.sh restart ================
Stopping zookeeper ... STOPPED
Starting zookeeper ... STARTED

5、验证堆内存

[root@ELK102 ~]# jmap -heap `jps | awk '/QuorumPeerMain/{print $1}'` | grep MaxHeapSize
   MaxHeapSize              = 268435456 (256.0MB)

kafka堆内存调优

1、查看堆内存大小

[root@ELK101 ~]# jmap -heap `jps | awk '/Kafka/{print $1}'` | grep MaxHeapSize
   MaxHeapSize              = 1073741824 (1024.0MB)

2、修改堆内存(生产环境5~6G最佳)

捎带启动了JXM端口

[root@ELK101 ~]# cat `which kafka-server-start.sh`
......
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
#    export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
    export KAFKA_HEAP_OPTS="-server -Xmx256M -Xms256M -
XX:PermSize=128m -XX:+UseG1GC -XX:MaxGCPauseMillis=200 
-XX:ParallelGCThreads=8 -XX:ConcGCThreads=5 -XX:Initiat
ingHeapOccupancyPercent=70"
    export JMX_PORT="8888"
fi
......

3、单点重启kafka,查看堆内存大小

[root@ELK101 ~]# kafka-server-stop.sh 
[root@ELK101 ~]# kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties
[root@ELK101 ~]# jmap -heap `jps | awk '/Kafka/{print $1}'` | grep MaxHeapSize
   MaxHeapSize              = 268435456 (256.0MB)

4、将启动脚本同步到其他节点

[root@ELK101 ~]# data_rsync.sh `which kafka-server-start.sh`
===== rsyncing elk102: kafka-server-start.sh =====
命令执行成功!
===== rsyncing elk103: kafka-server-start.sh =====
命令执行成功!

5、其他节点重启kafka环境,查看堆内存是否生效

[root@ELK101 ~]# manager_kafka.sh stop
停止服务
========== elk101 kafaka-server-stop.sh stop ================
========== elk102 kafaka-server-stop.sh stop ================
========== elk103 kafaka-server-stop.sh stop ================
[root@ELK101 ~]# manager_kafka.sh start
启动服务
========== elk101 kafaka-server-start.sh start ================
========== elk102 kafaka-server-start.sh start ================
========== elk103 kafaka-server-start.sh start ================
[root@ELK102 ~]# jmap -heap `jps | awk '/Kafka/{print $1}'` | grep MaxHeapSize
   MaxHeapSize              = 268435456 (256.0MB)
[root@ELK103 ~]# jmap -heap `jps | awk '/Kafka/{print $1}'` | grep MaxHeapSize
   MaxHeapSize              = 268435456 (256.0MB)

kafka开源监控组件kafka-eagle

图形化的方式管理kafka

一、前期准备

1、启动kafka的JMX端口

与上面修改堆内存步骤相同,略。

2、启动zookeeper的JMX端口

[root@ELK101 ~]# cat /koten/softwares/apache-zookeeper-3.8.1-bin/bin/zkEnv.sh
# zookeeper JMX
JMXLOCALONLY=false
JMXHOSTNAME=10.0.0.101
JMXPORT=9999
JMXSSL=false
JMXLOG4J=false

3、安装mysql,启动服务并设置开机自启动

[root@ELK101 ~]# yum -y install mariadb-server
[root@ELK101 ~]# cat /etc/my.cnf    
[mysqld]
......
skip-name-resolve=1 #跳过名称解析,不跳过再进行登录的时候,可能会进行反向解析
[root@ELK101 ~]# systemctl enable --now mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

4、创建数据库与授权用户

[root@ELK101 ~]# mysql

5、测试用户

[root@ELK101 ~]# mysql -u admin -pkoten -h 10.0.0.101
Welcome to the MariaDB monitor.  Commands end with ; or \g.

3 rows in set (0.00 sec)

MariaDB [(none)]> quit
Bye

二、部署监控

1、下载kafka-eagle软件,下面的链接下载的慢可以用我分享在文末的链接

[root@ELK101 ~]# wget https://github.com/smartloli/kafka-eagle-bin/archive/v2.0.8.tar.gz

2、解压软件包

[root@ELK101 ~]# unzip kafka-eagle-bin-2.0.8.zip 
Archive:  kafka-eagle-bin-2.0.8.zip
  inflating: efak-web-2.0.8-bin.tar.gz  
  inflating: system-config.properties  
[root@ELK101 ~]# tar xf efak-web-2.0.8-bin.tar.gz -C /koten/softwares/

3、修改配置文件

[root@ELK101 ~]# cat /koten/softwares/efak-web-2.0.8/conf/system-config.properties
efak.zk.cluster.alias=kafka
kafka.zk.list=10.0.0.101:2181,10.0.0.102:2181,10.0.0.103:2181/kafka-3.2.1  #注意chroot与kafka配置文件保持一致
kafka.efak.broker.size=20
kafka.zk.limit.size=16
efak.webui.port=8048
kafka.efak.offset.storage=zk
kafka.efak.jmx.uri=service:jmx:rmi:///jndi/rmi://%s/jmxrmi
efak.metrics.charts=true
efak.metrics.retain=15
efak.sql.topic.records.max=5000
efak.sql.topic.preview.records.max=10
efak.topic.token=koten
efak.driver=com.mysql.cj.jdbc.Driver
efak.url=jdbc:mysql://10.0.0.101:3306/koten_kafka?useUnicode=true&characterEncodi
ng=UTF-8&zeroDateTimeBehavior=convertToNull
efak.username=admin
efak.password=koten   #数据库密码

4、配置环境变量

[root@ELK101 ~]# cat >> /etc/profile.d/kafka.sh <<'EOF'
export KE_HOME=/koten/softwares/efak-web-2.0.8
export PATH=$PATH:$KE_HOME/bin
EOF
[root@ELK101 ~]# source /etc/profile.d/kafka.sh

5、修改配置启动脚本的堆内存大小

[root@ELK101 ~]# sed -i '/KE_JAVA_OPTS/s#2g#256m#g'  $KE_HOME/bin/ke.sh | grep KE_JAVA_OPTS
[root@ELK101 ~]# grep KE_JAVA_OPTS $KE_HOME/bin/ke.sh
export KE_JAVA_OPTS="-server -Xmx256m -Xms256m -XX:MaxGCPauseMillis=20 -XX:+UseG1GC -XX:MetaspaceSize=128m -XX:InitiatingHeapOccupancyPercent=35 -XX:G1HeapRegionSize=16M -XX:MinMetaspaceFreeRatio=50 -XX:MaxMetaspaceFreeRatio=80"

6、启动服务

[root@ELK101 ~]# ke.sh start
......

7、登录eagle

zookeeper 添加清理参数_zookeeper 添加清理参数

8、忘记密码后可以进入数据库去找

MariaDB [koten_kafka]> SELECT * FROM koten_kafka.ke_users;
+----+-------+----------+-----------+-----------------+---------------+
| id | rtxno | username | password  | email           | realname      |
+----+-------+----------+-----------+-----------------+---------------+
|  1 |  1000 | admin    | 123456    | admin@email.com | Administrator |
+----+-------+----------+-----------+-----------------+---------------+
1 row in set (0.00 sec)

MariaDB [koten_kafka]>

9、登陆进去后可以看到监控的kafka与zookeeper的一些数据信息

查看仪表盘

zookeeper 添加清理参数_zookeeper_02

查看zookeeper与kafka的监控信息

zookeeper 添加清理参数_kafka_03

10、不止可以监控数据,还可以创建topic,对kafka集群进行一些操作

zookeeper 添加清理参数_java_04

zookeeper 添加清理参数_java_05

zookeeper 添加清理参数_zookeeper_06

kafka集群压力测试 

对kafka集群进行压力测试,方便我们了解集群的处理上限,可以作为集群调优和扩容的依据。

测试之前要先搞懂链路,如果你的生产者与kafka集群不在一个地方,那么你在一个主机进行压力测试也没有意义,确定好链路后,在实际的生产者和消费者执行压测,修改对应的主机参数即可。

1、通过下面脚本进行压测

mkdir /tmp/kafka-test

cat > kafka-test.sh <<'EOF'
# 创建topic
kafka-topics.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic kafka-2023 --replication-factor 1 --partitions 10 --create

# 启动消费者消费数据
nohup kafka-consumer-perf-test.sh --broker-list 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic  kafka-2023 --messages 100000 &>/tmp/kafka-test/kafka-consumer.log &

# 启动生产者写入数据
nohup kafka-producer-perf-test.sh --num-records 100000 --record-size 1000 --topic  kafka-2023 --throughput 1000 --producer-props bootstrap.servers=10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 &> /tmp/kafka-test/kafka-producer.log &
EOF

bash kafka-test.sh 


#可以根据自己要测的实际生产情况调整以下参数

kafka-consumer-perf-test.sh 

---messages: 指定消费消息的数量。
--broker-list: 指定broker列表。
--topic: 指定topic主体。
        
kafka-producer-perf-test.sh 

-num-records:生产消息的数量。
--record-size: 每条消息的大小,单位是字节。
--topic: 指定topic主体。
--throughput: 设置每秒发送的消息数量,即指定最大消息的吞吐量,若设置为-1代表不限制!
--producer-props bootstrap.servers: 指定broker列表

 2、可以通过efak查看实施进度

zookeeper 添加清理参数_zookeeper 添加清理参数_07

zookeeper 添加清理参数_zookeeper 添加清理参数_08

3、也可以通过脚本输出的日志观察生产和消费速度

zookeeper 添加清理参数_运维_09

zookeeper 添加清理参数_zookeeper_10

filebeat对接kafka

filebeat对接kafka,如果filebeat作为生产者,kafka作为消费者,可以经过kafka后再写入到es集群;filebeat作为消费者,可以读取到kafka的数据,将kafka的数据展示出来,或者写入es集群。下面给大家展示下示例。

一、filebeat作为生产者

filebeat作为生产者,所以是output到kafka,input我们就用stdin去测试。

1、kafka启动消费者

[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic filebeat-to-kafka

2、执行filebeat

[root@ELK101 config]# cat 01-stdin-to-kafka.yaml 
filebeat.inputs:
- type: stdin

output.kafka:
  hosts: ["10.0.0.101:9092", "10.0.0.102:9092", "10.0.0.103:9092"]
  topic: 'filebeat-to-kafka'

# 执行filebeat并输入测试数据
[root@ELK101 config]# filebeat -e -c config/01-stdin-to-kafka.yaml
...
1234567

# kafka会消费到数据
[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic filebeat-to-kafka
[2023-12-18 15:51:33,774] WARN [Consumer clientId=console-consumer, groupId=console-consumer-60747] Error while fetching metadata with correlation id 2 : {filebeat-to-kafka=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

二、filebeat作为消费者

1、启动filebeat进行消费

[root@ELK101 config]# cat 02-kafka-to-filebeat.yaml 
filebeat.inputs:
- type: kafka
  hosts:
    - 10.0.0.101:9092
    - 10.0.0.102:9092
    - 10.0.0.103:9092
  topics: ["kafka-to-filebeat"]
  group_id: "filebeat"

output.console:
  pretty: true

[root@ELK101 config]# filebeat -e -c config/02-kafka-to-filebeat.yaml

2、启动kafka进行生产

[root@ELK101 ~]# kafka-console-producer.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic kafka-to-filebeat

}

logstash对接kafka

一、logstash作为生产者

1、kafaka开始消费

[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic logstash-to-kafka

2、启动logstash开始生产

[root@ELK101 logstash_cofig]# cat 01-logstash-to-kafka.yaml
input {
  stdin {
  }
}

output {
  kafka {
    bootstrap_servers => "10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092"
    topic_id => "logstash-to-kafka"
  }
}

# 启动logstash并手动写入数据
[root@ELK101 logstash_cofig]# logstash -r -f 01-logstash-to-kafka.yaml
...
ceshi123

# kafka可以消费到数据
[root@ELK101 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.101:9092,10.0.0.102:9092,10.0.0.103:9092 --topic logstash-to-kafka
