这里是weihubeats,觉得文章不错可以关注公众号小奏技术，文章首发。拒绝营销号，拒绝标题党
kafka版本
- kafka_2.13-3.5.0
背景
继之前Linux Kafka 3.5 KRaft模式集群部署:weihubeats.blog.csdn.net/article/det…
我们采用的 一个节点即是broker又是controller，这种部署方式仅适合于测试环境，本次我们要实现线上环境的Kafka部署
所以我们的部署方式为broker和controller分离
容量评估
- qps:假设
qps1000左右 - 磁盘: 假设每天消息量1000w左右，每条消息大小2M，消息保存时间为14天。副本为2个。那么总的磁盘空间为 1000w * 2M * 14 * 2 / 1024 = 54g左右，还有其他索引数据啥的，预留10% 大概50~60g左右，所以暂时100g够用。磁盘扩容比价方便
机器
所以暂时选着5台机器部署
- 3台部署KRaft
- 2台部署broker
机器配置暂时都是4核16g，磁盘100g
这里和测试环境部署不一样的是broker和controller是独立部署的
假设我们的机器ip是
| 机器 | ip | 域名 | 部署角色 |
|---|---|---|---|
| 1 | 192.168.1.1 | kafka-controller-prd-001.com | controller |
| 2 | 192.168.1.2 | kafka-controller-prd-002.com | controller |
| 3 | 192.168.1.3 | kafka-controller-prd-003.com | controller |
| 4 | 192.168.1.4 | kafka-prd-001.com | broker |
| 5 | 192.168.1.5 | kafka-prd-002.com | broker |
注意所有机器的9092、9093、9099端口都打开
注意为了保证高可用最好保证部署broker和controller不同副本在不同的可用区
配置文件
controller
controller2和controller3的配置和controller1其实是差不多的，只不过node.id不同，其次是listeners要对应自己的域名
注意
node.id中的id和controller.quorum.voters中的数字要对应上
controller1

部署
1. 安装jdk11
sudo apt update
apt install openjdk-11-jdk -y
5台机器执行
2. 下载kafka二进制包
wget http://mirrors.aliyun.com/apache/kafka/3.5.0/kafka_2.13-3.5.0.tgz
5台机器执行
3. 解压
tar -xzf kafka_2.13-3.5.0.tgz
5台机器执行
4. 给集群生成一个UUID
kafka_2.13-3.0.0/bin/kafka-storage.sh random-uuid
单台机器执行即可
这里我生成的UUID为mzXiaoZouNnbe32DRMpSkX
5. 修改配置文件
1、2、3机器修改controller配置
即kafka_2.13-3.5.0/config/kraft/controller.properties
4、5机器修改配置kafka_2.13-3.5.0/config/kraft/broker.properties
6. 启动集群
启动controller
按顺序依次启动集群启动controller1、controller2、controller3
启动步骤(每个controller启动都是执行如下脚本)
sh /home/ubuntu/kafka_2.13-3.5.0/bin/kafka-storage.sh format -t mzDehZx0RNmke27PRMpNkA -c /home/ubuntu/kafka_2.13-3.5.0/config/kraft/controller.properties
export KAFKA_HEAP_OPTS="-Xmx11G -Xms11G"&&JMX_PORT=9988 nohup sh /data/kafka_2.13-3.5.0/bin/kafka-server-start.sh /data/kafka_2.13-3.5.0/config/kraft/controller.properties &
启动broker
按顺序依次启动集群启动broker1、broker2
sh /home/ubuntu/kafka_2.13-3.5.0/bin/kafka-storage.sh format -t mzDehZx0RNmke27PRMpNkA -c /home/ubuntu/kafka_2.13-3.5.0/config/kraft/broker.properties
export KAFKA_HEAP_OPTS="-Xmx11G -Xms11G"&&JMX_PORT=9988 nohup sh /data/kafka_2.13-3.5.0/bin/kafka-server-start.sh /data/kafka_2.13-3.5.0/config/kraft/broker.properties &
接入点
由于我们之前设置了域名，所以我们的接入点是
kafka-prd-001.com:9092,kafka-prd-002.com:9092
删除元数据
如果要删除启动的元数据重新部署
rm -rf /tmp/kafka-logs /tmp/kraft-controller-logs /tmp/kraft-combined-logs
测试
测控和之前一样 可以参考 Linux Kafka 3.5 KRaft模式集群部署:weihubeats.blog.csdn.net/article/det…
