kafka 设置用户密码和通过SpringBoot测试-Toy模板网

这篇具有很好参考价值的文章主要介绍了kafka 设置用户密码和通过SpringBoot测试。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

叙述

当前Kafka认证方式采用动态增加用户协议。

自0.9.0.0版本开始Kafka社区添加了许多功能用于提高Kafka群集的安全性，Kafka提供SSL或者SASL两种安全策略。SSL方式主要是通过CA令牌实现，此文主要介绍SASL方式。

1）SASL验证:

验证方式	Kafka版本	特点
SASL/PLAIN	0.10.0.0	不能动态增加用户
SASL/SCRAM	0.10.2.0	可以动态增加用户
SASL/Kerberos	0.9.0.0	需要独立部署验证服务
SASL/OAUTHBEARER	2.0.0	需自己实现接口实现token的创建和验证，需要额外Oauth服务

2）SSL加密: 使用SSL加密在代理和客户端之间，代理之间或代理和工具之间传输的数据。

操作

1、进入kafka目录，修改kafka配置文件，修改config/server.properties文件，并添加如下内容

vi config/server.properties

修改内容：

#配置zookeeper管理kafka的路径
zookeeper.connect=localhost:2181

#配置kafka的监听端口（SASL_PLAINTEXT：动态增加用户协议，PLAINTEXT 不能动态增加用户）
listeners=SASL_PLAINTEXT://:9092

#把kafka的地址端口注册给zookeeper，如果是远程访问要改成外网IP（SASL_PLAINTEXT：动态增加用户协议，PLAINTEXT 不能动态增加用户）
advertised.listeners=SASL_PLAINTEXT://你外网的ip:9092


#使用的认证协议（SASL_PLAINTEXT：动态增加用户协议，PLAINTEXT 不能动态增加用户）
security.inter.broker.protocol=SASL_PLAINTEXT

#SASL机制
sasl.enabled.mechanisms=PLAIN
sasl.mechanism.inter.broker.protocol=PLAIN

#完成身份验证的类
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer

#如果没有找到ACL（访问控制列表）配置，则允许任何操作。
allow.everyone.if.no.acl.found=false

#需要开启设置超级管理员,设置visitor用户为超级管理员
super.users=User:visitor

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

# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0

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

# The address the socket server listens on. It will get the value returned from 
# java.net.InetAddress.getCanonicalHostName() if not configured.
#   FORMAT:
#     listeners = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
#listeners=PLAINTEXT://:9092

# Hostname and port the broker will advertise to producers and consumers. If not set, 
# it uses the value for "listeners" if configured.  Otherwise, it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
#advertised.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
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=/usr/local/kafka/kafka-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=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

############################# Zookeeper #############################

# Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.
zookeeper.connect=localhost:2181

# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=18000


############################# Group Coordinator Settings #############################

# The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance.
# The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms.
# The default value for this is 3 seconds.
# We override this to 0 here as it makes for a better out-of-the-box experience for development and testing.
# However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.
group.initial.rebalance.delay.ms=0


#配置zookeeper管理kafka的路径
zookeeper.connect=localhost:2181

#配置kafka的监听端口（SASL_PLAINTEXT：动态增加用户协议，PLAINTEXT 不能动态增加用户）
listeners=SASL_PLAINTEXT://:9092

#把kafka的地址端口注册给zookeeper，如果是远程访问要改成外网IP（SASL_PLAINTEXT：动态增加用户协议，PLAINTEXT 不能动态增加用户）
advertised.listeners=SASL_PLAINTEXT://你外网的ip:9092


#使用的认证协议（SASL_PLAINTEXT：动态增加用户协议，PLAINTEXT 不能动态增加用户）
security.inter.broker.protocol=SASL_PLAINTEXT

#SASL机制
sasl.enabled.mechanisms=PLAIN
sasl.mechanism.inter.broker.protocol=PLAIN

#完成身份验证的类
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer

#如果没有找到ACL（访问控制列表）配置，则允许任何操作。
allow.everyone.if.no.acl.found=false

#需要开启设置超级管理员,设置visitor用户为超级管理员
super.users=User:visitor

2、在kafka目录下新建pass目录，并且创建配置文件，填入如下内容。

创建目录

mkdir pass

创建 kafka_server_jaas.conf 文件

vi kafka_server_jaas.conf

填入如下内容

KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
        username="visitor"
        password="qaz@123"
        user_visitor="qaz@123";
};

3、在当前kafka目录下，修改kafka启动脚本

vi bin/kafka-server-start.sh

在文件最上面添加变量

export KAFKA_OPTS=" -Djava.security.auth.login.config=/usr/local/kafka2.12/pass/kafka_server_jaas.conf"

全部配置内容

Kafka消费者提供者客户端验证

注意：如果你只需要使用Kafka连接SpringBoot验证，那么这一步可以不做！

进入kafka目录，在pass目录下创建kafka_client_jaas.conf文件，并写入如下内容。

KafkaClient {  
org.apache.kafka.common.security.plain.PlainLoginModule required  
    username="visitor"  
    password="qaz@123";  
};

提供者

1、配置提供者认证，修改提供者启动脚本，并在顶部写入下面内容。

vi bin/kafka-console-producer.sh

顶部写入下面内容

export KAFKA_OPTS=" -Djava.security.auth.login.config=/usr/local/kafka2.12/pass/kafka_client_jaas.conf"
