如何查看麒麟的系统架构

需要在信创平台（鲲鹏ARM CPU 和 银河麒麟V10操作系统）部署Kafka存储实时采集的日志数据，需要注意的是只需要配置好ARM 版本的JDK即可。

一 、 环境信息

名称	版本	备注
操作系统	银河麒麟 V10 SP3
CPU型号	鲲鹏 920
JDK	bisheng-jdk-17.0.8-linux-aarch64	毕昇JDK 17
Apache Kafka	3.5.1	从3.1.0开始支持JDK17

二、 JDK环境配置

所有节点都需要

2.1 银河麒麟系统自带JDK卸载

• 系统自带JDK如果存在就卸载，最小化模式安装的系统没有自带JDK

yum -y remove java-1.8.0*
yum -y remove java-11*

2.2 毕昇JDK 17 安装

• 下载并解压安装

sudo mkdir -p /opt/soft/java
cd /opt/soft/java/
wget https://mirrors.huaweicloud.com/kunpeng/archive/compiler/bisheng_jdk/bisheng-jdk-17.0.8-linux-aarch64.tar.gz
tar -zxf bisheng-jdk-17.0.8-linux-aarch64.tar.gz
rm bisheng-jdk-17.0.8-linux-aarch64.tar.gz
ln -snf bisheng-jdk-17.0.8 java

• 配置环境变量

sudo su - -c 'cat >> /etc/profile << EOF
export JAVA_HOME=/opt/soft/java/java
export PATH=\$PATH:\$JAVA_HOME/bin
EOF'

• 使环境变量生效

source /etc/profile

三、Kafka部署

所有节点都需要

3.1 创建Kafka用户

adduser kafka

3.2 创建相关目录

# 创建kafka安装目录
mkdir -p /opt/soft/kafka
chown -R kafka:kafka /opt/soft/kafka
# 创建Kafka数据存储目录
mkdir -p /data/kafka
chown -R kafka:kafka /data/kafka
# 创建kafka 运行日志存储目录
mkdir -p /var/log/kafka
chown -R kafka:kafka /var/log/kafka

3.3 下载安装包并解压安装

sudo su - kafka
wget https://downloads.apache.org/kafka/3.5.1/kafka_2.12-3.5.1.tgz
# 解压安装
tar -zxf kafka_2.12-3.5.1.tgz -C /opt/soft/kafka
# 创建软连接
cd /opt/soft/kafka
ln -snf kafka_2.12-3.5.1 kafka

四、配置Kafka

4.1 修改 server.properties

进入Kafka安装目录，编辑 config/kraft/server.properties 文件，配置以下参数：

• process.roles : 保持默认值 broker,controller 即可，每个节点同时担任 broker 和 controller 两个角色
• node.id ：设置Kafka 节点的唯一标识，每台服务器上的 ID应该不同。
• controller.quorum.voters : 设置controller节点的IP和端口，格式 [nodeId]@[nodeip]:[port] , 多个controller 使用 , 隔开
• delete.topic.enable : 设置为 true ,表示允许删除 topic
• listeners：设置Kafka Broker 和 Controller 监听的地址和端口，例如PLAINTEXT://:9092,CONTROLLER://:9093 。
• log.dirs：设置Kafka Broker的日志目录，用于存储消息数据

完整 server.properties 内容如下：

#

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

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

# The node id associated with this instance's roles
# 不通的节点需要设置不通的 ID
node.id=1

# The connect string for the controller quorum
controller.quorum.voters=1@192.168.91.101:9093,2@192.168.91.102:9093,3@192.168.91.103:9093

delete.topic.enable=true
############################# Socket Server Settings #############################

# The address the socket server listens on.
# Combined nodes (i.e. those with `process.roles=broker,controller`) must list the controller listener here at a minimum.
# If the broker listener is not defined, the default listener will use a host name that is 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://:9092,CONTROLLER://:9093

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

# Listener name, hostname and port the broker will advertise to clients.
# If not set, it uses the value for "listeners".
#advertised.listeners=PLAINTEXT://:9092

# A comma-separated list of the names of the listeners used by the controller.
# If no explicit mapping set in `listener.security.protocol.map`, default will be using PLAINTEXT protocol
# This is required if running in KRaft mode.
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 that the server uses for receiving requests from the network and sending responses to the network
num.network.threads=3

# The number of threads that the server uses for processing requests, which may include disk I/O
num.io.threads=8

# The send buffer (SO_SNDBUF) used by the socket server
socket.send.buffer.bytes=102400

# The receive buffer (SO_RCVBUF) used by the socket server
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=/data/kafka

# 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=1

# 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=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1

############################# 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

4.2 ## 配置运行日志目录

Kafka运行时日志默认输出到$KAFKA_HOME/logs目录下，容易撑爆分区，造成操作系统崩溃。需要将日志输出到指定分区，修改 kafka-run-class.sh 脚本增加一行 LOG_DIR=“/var/log/kafka”

LOG_DIR=/var/log/kafka ## 增加这一行
# Log directory to use
if [ "x$LOG_DIR" = "x" ]; then
  LOG_DIR="$base_dir/logs"
fi

五、启动kafka,并验证是否正常运行

5.1 在任意节点生成一个唯一的集群ID

/opt/soft/kafka/kafka/bin/kafka-storage.sh random-uuid

• 运行结果如下

G51vd1iCQRWn-43rdcMJUg

5.2 格式化数据存储目录

在每个节点执行以下命令

/opt/soft/kafka/kafka/bin/kafka-storage.sh format \
-t G51vd1iCQRWn-43rdcMJUg \
-c config/kraft/server.properties

5.3 启动Kafka Server

在每个节点执行以下命令

/opt/soft/kafka/kafka/bin/kafka-server-start.sh -daemon \
config/kraft/server.properties

5.4 验证集群状态

1. 创建主题

/opt/soft/kafka/kafka/bin/kafka-topics.sh \
--bootstrap-server localhost:9092 \
--create --topic test \
--partitions 3 \
--replication-factor 3

2. 查看主题

/opt/soft/kafka/kafka/bin/kafka-topics.sh \
--bootstrap-server localhost:9092 \
--describe test

3. 控制台生产者测试

/opt/soft/kafka/kafka/bin/kafka-console-producer.sh \
--bootstrap-server localhost:9092 \
--topic test

4. 控制台消费者测试

/opt/soft/kafka/kafka/bin/kafka-console-consumer.sh \
--bootstrap-server localhost:9092 \
--topic test \
--from-beginning

5. 查看 kafka 运行日志

tail -f /var/log/kafka/server.log
