Linux-Kafka 3.7.0 Kraft+SASL认证模式 集群安装与部署超详细

1.集群规划

一般模式下，元数据在 zookeeper 中，运行时动态选举 controller，由controller 进行 Kafka 集群管理。kraft 模式架构（实验性）下，不再依赖 zookeeper 集群，而是用三台 controller 节点代替 zookeeper，元数据保存在 controller 中，由 controller 直接进行 Kafka 集群管理。

好处有以下几个：

  • Kafka 不再依赖外部框架，而是能够独立运行
  • controller 管理集群时，不再需要从 zookeeper 中先读取数据，集群性能上升
  • 由于不依赖 zookeeper，集群扩展时不再受到 zookeeper 读写能力限制
  • controller 不再动态选举，而是由配置文件规定。可以有针对性的加强controller 节点的配置，而不是像以前一样对随机 controller 节点的高负载束手无策。

    2.集群部署

1.下载kafka二进制包

https://kafka.apache.org/downloads

2.解压

tar -zxvf /data/kafka_2.13-3.7.0.tgz

3.修改配置文件(kfka1 192.172.21.120上节点的配置为例)

cd /usr/kafka/kafka_2.13-3.7.0/config/kraft
vi server.properties

注：Kraft模式的配置文件在config目录的kraft子目录下

# 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
#角色
process.roles=broker,controller

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

# The connect string for the controller quorum
[email protected]:19093,[email protected]:19093,[email protected]:19093

############################# 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 19092.
#   FORMAT:
#     listeners = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:19092
listeners=SASL_PLAINTEXT://192.172.21.120:19092,CONTROLLER://192.172.21.120:19093
# Name of listener used for communication between brokers.
inter.broker.listener.name=SASL_PLAINTEXT

# Listener name, hostname and port the broker will advertise to clients.
# If not set, it uses the value for "listeners".
advertised.listeners=SASL_PLAINTEXT://192.172.21.120:19092

# 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
#CONTROLLER:SASL_PLAINTEXT需要修改
listener.security.protocol.map=CONTROLLER:SASL_PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL
# 设置必须授权才能用
allow.everyone.if.no.acl.found=false
# 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/datas

# 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
# 认证方式，用了最简单的PLAIN，缺点是不能动态添加用户
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
sasl.mechanism=PLAIN
# 禁用了自动创建topic
auto.create.topics.enable = false
# 设置必须授权才能用
allow.everyone.if.no.acl.found=false
# 设置超级管理员
super.users=User:admin
# 这个是3.2.0版本新引入的认证方式，可以参考 https://cwiki.apache.org/confluence/display/KAFKA/KIP-801%3A+Implement+an+Authorizer+that+stores+metadata+in+__cluster_metadata
authorizer.class.name=org.apache.kafka.metadata.authorizer.StandardAuthorizer
# 集群间认证时用的认证方式
sasl.mechanism.controller.protocol=PLAIN

5.在其他节点上修改配置文件

在 192.172.21.121 和 192.172.21.122 上修改配置文件

server.properties

中

1.
node.id

注：node.id 不得重复，整个集群中唯一，且值需要和controller.quorum.voters 对应。

2.
dvertised.Listeners

地址

根据各自的主机名称，修改相应的 dvertised.Listeners 地址

3.listeners地址

根据各自的主机IP修改

节点 ID

node.id=2

#不同服务器绑定的端口
listeners=SASL_PLAINTEXT://192.172.21.121:19092,CONTROLLER://192.172.21.121:19093

侦听器名称、主机名和代理将向客户端公布的端口.(broker 对外暴露的地址)

如果未设置，则使用"listeners"的值.

advertised.listeners=SASL_PLAINTEXT://192.172.21.121:19092

节点 ID

node.id=3

#不同服务器绑定的端口
listeners=SASL_PLAINTEXT://192.172.21.122:19092,CONTROLLER://192.172.21.122:19093

侦听器名称、主机名和代理将向客户端公布的端口.(broker 对外暴露的地址)

如果未设置，则使用"listeners"的值.

advertised.listeners=SASL_PLAINTEXT://192.172.21.122:19092

6.创建Kraft账号密码认证文件

KafkaServer {
   org.apache.kafka.common.security.plain.PlainLoginModule required
   username="admin"
   password="password"
   user_admin="password"
   user_test="test";
};
  • username/password 表示了认证时用的用户。
  • suer_admin="password",这个表示一个用户名为admin用户，密码是password，这个必须要有一个，且要这一个跟上面的username和password保持一致。
  • user_test="test" 是第二个用户，表示的是用户名为test的账户，密码为test。

7.初始化集群数据目录

1.首先生成存储目录唯一 ID。

bin/kafka-storage.sh random-uuid
输出ID：Mu_PwVjLQGGYBcE_EjCfmA

2.用该 ID 格式化 kafka 存储目录（每个节点都需要执行）

bin/kafka-storage.sh format -t Mu_PwVjLQGGYBcE_EjCfmA -c /data/kafka/kafka_2.13-3.7.0/config/kraft/server.properties

8.启动集群

1.配置kafka服务的启动脚本

cp kafka-server-start.sh kafka-server-start-sasl.sh

if [ $# -lt 1 ];
then
        echo "USAGE: $0 [-daemon] server.properties [--override property=value]*"
        exit 1
fi
base_dir=$(dirname $0)

if [ "x$KAFKA_LOG4J_OPTS" = "x" ]; then
    export KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/../config/log4j.properties"
fi

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
#将创建的kafka_server_jaas.conf地址添加到下面
    export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G -Djava.security.auth.login.config=/data/kafka/config/kafka_server_jaas.conf"
fi

EXTRA_ARGS=${EXTRA_ARGS-'-name kafkaServer -loggc'}

COMMAND=$1
case $COMMAND in
  -daemon)
    EXTRA_ARGS="-daemon "$EXTRA_ARGS
    shift
    ;;
  *)
    ;;
esac

exec $base_dir/kafka-run-class.sh $EXTRA_ARGS kafka.Kafka "$@"

kafka_2.13-3.6.0-1、kafka_2.13-3.6.0-2、kafka_2.13-3.6.0-3修改部分为：

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
    export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G -Djava.security.auth.login.config=/data/kafka-cluster/global_config/kafka_server_jaas.conf"
fi
2.在节点上依次启动 Kafka
kafka-server-start-sasl.sh -daemon /data/kafka/kafka_2.13-3.7.0/config/kraft/server.properties

9.命令测试集群

1.先创建一个用于client的认证文件
vim jaas.properties

  1. 配置上一个用户
sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required  username="admin"  password="password";
security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAI

#执行命令式，后面都要带上 --command-config ./jaas.properties来进行用户认证
3.创建 topic create-for-test 到bin下面

bin/kafka-topics.sh --bootstrap-server 192.172.21.120:19092  --create  --topic repair.queue --partitions 1 --replication-factor 1  --command-config /data/kafka/config/jaas.properties
  1. 查看topic应该只能看到 create-for-test
./kafka-console-producer.sh broker-list --bootstrap-server 192.172.21.120:19092 --topic create-for-test  --producer.config /data/kafka/config/jaas.properties

4.测试进行消费先创建kafka_client_jaas.conf 

KafkaClient {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="password";
};

5.修改kafka-console-producer.sh和kafka-console-consumer.sh启动文件两个都要改

#!/bin/bash

# contributor license agreements.  See the NOTICE file distributed with
# this work for additional information regarding copyright ownership.

# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
# See the License for the specific language governing permissions and
# limitations under the License.

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
    export KAFKA_HEAP_OPTS="-Xmx512M"
fi
#添加-Djava.security.auth.login.config=/data/kafka/config/kafka_client_jaas.conf
exec $(dirname $0)/kafka-run-class.sh  -Djava.security.auth.login.config=/data/kafka/config/kafka_client_jaas.conf kafka.tools.ConsoleProducer "$@"

6.打开生产监控等待消费查看

./kafka-console-producer.sh broker-list --bootstrap-server 192.172.21.120:19092   --topic s_system_trace_topic  --producer.config /data/kafka/config/jaas.properties

7.进消费数据在生产监控看到这样就完成测试了

./kafka-console-consumer.sh --bootstrap-server 192.172.21.120:19092  --topic create-for-test --from-beginning --consumer.config /data/kafka/config/jaas.properties

8.删除测试主题

bin/kafka-topics.sh --bootstrap-server 192.172.21.120:19092  --delete --topic create-for-test --command-config /data/kafka/config/jaas.properties
