Kafka KRaft线上集群部署实战(broker、controller分离部署)

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:https://weihubeats.blog.csdn.net/article/details/132736141

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

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

############################# Server Basics #############################

# The role of this server. Setting this puts us in KRaft mode
process.roles=controller

# The node id associated with this instance's roles
node.id=1

# The connect string for the controller quorum
controller.quorum.voters=1@kafka-controller-prd-001.com:9093,2@kafka-controller-prd-001.com:9093,3@kafka-controller-prd-001.com:9093

############################# Socket Server Settings #############################

# The address the socket server listens on.
# Note that only the controller listeners are allowed here when `process.roles=controller`, and this listener should be consistent with `controller.quorum.voters` value.
#   FORMAT:
#     listeners = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092

# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details
#listener.security.protocol.map=PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL

# The number of threads that the server uses for receiving requests from the network and sending responses to the network

socket.receive.buffer.bytes=102400

# The maximum size of a request that the socket server will accept (protection against OOM)
socket.request.max.bytes=104857600


############################# Log Basics #############################

# A comma separated list of directories under which to store log files
log.dirs=/tmp/kraft-controller-logs

# The default number of log partitions per topic. More partitions allow greater
# parallelism for consumption, but this will also result in more files across
# the brokers.
num.partitions=2

# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
# This value is recommended to be increased for installations with data dirs located in RAID array.
num.recovery.threads.per.data.dir=1

############################# Internal Topic Settings  #############################
# The replication factor for the group metadata internal topics "__consumer_offsets" and "__transaction_state"
# For anything other than development testing, a value greater than 1 is recommended to ensure availability such as 3.
offsets.topic.replication.factor=2
transaction.state.log.replication.factor=2
transaction.state.log.min.isr=2

############################# Log Flush Policy #############################

# Messages are immediately written to the filesystem but by default we only fsync() to sync
# the OS cache lazily. The following configurations control the flush of data to disk.
# There are a few important trade-offs here:
#    1. Durability: Unflushed data may be lost if you are not using replication.
#    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
# every N messages (or both). This can be done globally and overridden on a per-topic basis.

# The number of messages to accept before forcing a flush of data to disk
#log.flush.interval.messages=10000

# The maximum amount of time a message can sit in a log before we force a flush
#log.flush.interval.ms=1000

############################# Log Retention Policy #############################

# The following configurations control the disposal of log segments. The policy can
# be set to delete segments after a period of time, or after a given size has accumulated.
# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
# from the end of the log.

# The minimum age of a log file to be eligible for deletion due to age
log.retention.hours=168

# A size-based retention policy for logs. Segments are pruned from the log unless the remaining
# segments drop below log.retention.bytes. Functions independently of log.retention.hours.
#log.retention.bytes=1073741824

# The maximum size of a log segment file. When this size is reached a new log segment will be created.
log.segment.bytes=1073741824

# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies
log.retention.check.interval.ms=300000

#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
# every N messages (or both). This can be done globally and overridden on a per-topic basis.

# This configuration file is intended for use in KRaft mode, where
# Apache ZooKeeper is not present.
#

############################# Server Basics #############################

# The role of this server. Setting this puts us in KRaft mode
process.roles=broker

# The node id associated with this instance's roles
node.id=5

# The connect string for the controller quorum
controller.quorum.voters=1@kafka-controller-prd-001.com:9093,2@kafka-controller-prd-001.com:9093,3@kafka-controller-prd-001.com:9093

############################# Socket Server Settings #############################

# The address the socket server listens on. If not configured, the host name will be equal to the value of
# java.net.InetAddress.getCanonicalHostName(), with PLAINTEXT listener name, and port 9092.
#   FORMAT:
#     listeners = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
listeners=PLAINTEXT://kafka-prd-002.com:9092

# Name of listener used for communication between brokers.
inter.broker.listener.name=PLAINTEXT


# A comma-separated list of the names of the listeners used by the controller.
# This is required if running in KRaft mode. On a node with `process.roles=broker`, only the first listed listener will be used by the broker.
controller.listener.names=CONTROLLER

# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details
listener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL

# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
# This value is recommended to be increased for installations with data dirs located in RAID array.
num.recovery.threads.per.data.dir=1

############################# Internal Topic Settings  #############################
# The replication factor for the group metadata internal topics "__consumer_offsets" and "__transaction_state"
# For anything other than development testing, a value greater than 1 is recommended to ensure availability such as 3.
offsets.topic.replication.factor=2
transaction.state.log.replication.factor=2
transaction.state.log.min.isr=2

############################# Log Flush Policy #############################

# Messages are immediately written to the filesystem but by default we only fsync() to sync
# the OS cache lazily. The following configurations control the flush of data to disk.
# There are a few important trade-offs here:
#    1. Durability: Unflushed data may be lost if you are not using replication.
#    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
# every N messages (or both). This can be done globally and overridden on a per-topic basis.

# The number of messages to accept before forcing a flush of data to disk
#log.flush.interval.messages=10000

# The maximum amount of time a message can sit in a log before we force a flush
#log.flush.interval.ms=1000

############################# Log Retention Policy #############################

# The following configurations control the disposal of log segments. The policy can
# be set to delete segments after a period of time, or after a given size has accumulated.
# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
# from the end of the log.

# The minimum age of a log file to be eligible for deletion due to age
log.retention.hours=168

# A size-based retention policy for logs. Segments are pruned from the log unless the remaining
# segments drop below log.retention.bytes. Functions independently of log.retention.hours.
#log.retention.bytes=1073741824

# The maximum size of a log segment file. When this size is reached a new log segment will be created.
log.segment.bytes=1073741824

# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies

部署

1. 安装jdk11

sudo apt update
apt install openjdk-11-jdk -y
1
2

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
1

5台机器执行

3. 解压

tar -xzf kafka_2.13-3.5.0.tgz
1

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
1

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)

1. 格式化存储路径

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
1

2. 启动

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 &
1

启动broker

按顺序依次启动集群启动broker1、broker2

1. 格式化存储路径

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
1

2. 启动

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 &
1

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
1

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
1

测试

测控和之前一样 可以参考 Linux Kafka 3.5 KRaft模式集群部署:https://weihubeats.blog.csdn.net/article/details/132736141
