SASL/PLAIN方式

cd /usr/local/kafka/kafka_2.12-3.0.1/bin/
## 复制一份saslcp kafka-server-start.sh kafka-server-start-sasl.sh

在kafka-server-start-sasl.sh 末尾修改配置

exec $base_dir/kafka-run-class.sh $EXTRA_ARGS -Djava.security.auth.login.config=/usr/local/kafka/kafka_2.12-3.0.1/config/kafka-server-jaas.conf kafka.Kafka "$@"

或者在环境变量vim /etc/profile末尾增加如下配置：

if [ "x$KAFKA_OPTS" ]; thenexport KAFKA_OPTS="-Djava.security.auth.login.config=/usr/local/kafka/kafka_2.12-3.0.1/config/kafka-client-jaas.conf"
fi

config目录下增加kafka_server_jaas.conf文件

touch kafka-server-jaas.confKafkaServer {org.apache.kafka.common.security.plain.PlainLoginModule requiredusername="admin"password="admin"user_admin="admin"user_rex="123456"user_alice="123456"user_lucy="123456";
};

进入config目录将server.properties 复制一份改为server-sasl.properties 并添加如下配置：

listeners=SASL_PLAINTEXT://localhost:9092
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.enabled.mechanisms=PLAIN
sasl.mechanism.inter.broker.protocol=PLAIN
authorizer.class.name=kafka.security.authorizer.AclAuthorizer ## 如果kafka是3.0一下的配置authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer 因为kafka3.0开始已经移除了SimpleAclAuthorizer改用AclAuthorizer 如果还是配置SimpleAclAuthorizer 启动时会报ClassNotFoundException
super.users=User:admin

使用sasl认证启动kafka

./bin/kafka-server-start-sasl.sh -daemon config/server-sasl.properties

SASL/SCRAM方式

创建kafka用户

bin/kafka-configs.sh --zookeeper 127.0.0.1:2181/kafka --alter --add-config 'SCRAM-SHA-256=[password=admin],SCRAM-SHA-512=[password=admin]' --entity-type users --entity-name admin # 系统用户bin/kafka-configs.sh --zookeeper 127.0.0.1:2181/kafka --alter --add-config 'SCRAM-SHA-256=[password=chan_test],SCRAM-SHA-512=[password=chan_test]' --entity-type users --entity-name chan # 测试用户

可以看到在zk上已经创建了对应的用户信息，并且对密码做了加密

在kafka的config目录下创建jaas文件

 touch kafka_server_jaas_scram.confvim kafka_server_jaas_scram.confKafkaServer{
org.apache.kafka.common.security.scram.ScramLoginModule required
username="admin"
password="admin";
}

# 同时启用SCRAM和PLAIN机制
sasl.enabled.mechanisms=SCRAM-SHA-256,PLAIN
# 为broker间通讯开启SCRAM机制，采用SCRAM-SHA-512算法
sasl.mechanism.inter.broker.protocol=SCRAM-SHA-256
# broker间通讯使用PLAINTEXT
security.inter.broker.protocol=SASL_PLAINTEXT
# 配置listeners使用SASL_PLAINTEXT
listeners=SASL_PLAINTEXT://:9092
# 配置advertised.listeners
advertised.listeners=SASL_PLAINTEXT://127.0.0.1:9092#ACL配置
allow.everyone.if.no.acl.found=false
# 系统用户,多个分号隔开
super.users=User:admin;
authorizer.class.name=kafka.security.authorizer.AclAuthorizer

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=127.0.0.1:2181/kafka# 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.

拷贝一份启动脚本重命名为：kafka-server-start-scram.sh 修改kafka启动脚本注释最后一行并添加如下配置

#exec $base_dir/kafka-run-class.sh $EXTRA_ARGS kafka.Kafka "$@"
exec $base_dir/kafka-run-class.sh $EXTRA_ARGS -Djava.security.auth.login.config=/usr/local/kafka/kafka_2.12-3.0.1/config/kafka_server_jaas_scram.conf kafka.Kafka "$@"

启动kafka

./kafka-server-start-scram.sh -daemon ../config/server-scram.properties

注意：kafka连接的zk地址需要跟创建用户的zk节点一样，否则启动kafka会报认证失败

比如：server.properties 配置连接的zk是zookeeper.connect=127.0.0.1:2181/kafka ，这时创建用户的zk地址要bin/kafka-configs.sh --zookeeper 127.0.0.1:2181/kafka才可以如果zk没有kafka节点需要自己到zk上新建一个。

启动生产者和消费者

由于broker使用安全认证的方式启动，所以开启生产者和消费者也需要经过客户端认证。

在config目录下新建 producer.conf并添加以下配置

security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="admin" password="admin";

使用配置启动生产者

[root@hub kafka_2.12-3.0.1]# bin/kafka-console-producer.sh --bootstrap-server 127.0.0.1:9092 --topic test --producer.config config/producer.conf
>1
>2
>3
>

使用chan用户开启生产者

在config目录新建producer-chan.conf并添加以下配置

security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="chan" password="chan_test";

使用chan开启生产者,可以看到test这个topic是没有对chan这个用户做认证的，所以chan对这个用户没办法进行生产消息，这时候就需要进行授权。

[root@hub kafka_2.12-3.0.1]# bin/kafka-console-producer.sh --bootstrap-server 192.168.67.142:9092 --topic test --producer.config config/producer-chan.conf
>1
[2022-04-13 20:32:43,651] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 4 : {test=TOPIC_AUTHORIZATION_FAILED} (org.apache.kafka.clients.NetworkClient)
[2022-04-13 20:32:43,654] ERROR [Producer clientId=console-producer] Topic authorization failed for topics [test] (org.apache.kafka.clients.Metadata)

org.apache.kafka.common.errors.TopicAuthorizationException: Not authorized to access topics: [test]

开启消费者

[root@hub config]# cat consumer.conf
security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="admin" password="admin";

bin/kafka-console-consumer.sh --bootstrap-server 192.168.67.142:9092 --topic test --group 'test_group' --from-beginning --consumer.config config/consumer.conf

ACL授权

给chan这个用户授权，对test这个topic可以进行写操作

[root@hub kafka_2.12-3.0.1]# bin/kafka-acls.sh --authorizer-properties zookeeper.connect=127.0.0.1:2181/kafka --add --allow-principal User:chan --operation Write --topic 'test'
Adding ACLs for resource `ResourcePattern(resourceType=TOPIC, name=test, patternType=LITERAL)`: (principal=User:chan, host=*, operation=WRITE, permissionType=ALLOW) Current ACLs for resource `ResourcePattern(resourceType=TOPIC, name=test, patternType=LITERAL)`: (principal=User:chan, host=*, operation=WRITE, permissionType=ALLOW) [root@hub kafka_2.12-3.0.1]# bin/kafka-console-producer.sh --bootstrap-server 192.168.67.142:9092 --topic test --producer.config config/producer-chan.conf
>1
>2
>3
>

可以看到chan这个用户就可以往这个topic写数据了。
