kafka sasl/plain安全认证

1.SASL认证机制版本支持

SASL/GSSAPI (Kerberos) - starting at version 0.9.0.0
SASL/PLAIN - starting at version 0.10.0.0
SASL/SCRAM-SHA-256 and SASL/SCRAM-SHA-512 - starting at version 0.10.2.0

2.以下采用SASL/PLAIN进行认证操作

　　zookeeper配置

1）修改zoo.cfg增加两行配置：
authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
requireClientAuthScheme=sasl

2）配置JAAS文件：conf目录下创建zk_server_jaas.conf（定义了需要链接到Zookeeper服务器的用户名和密码）
Server {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="admin-sec";
};

3）加入需要的包：（从kafka下拷贝）
kafka-clients-0.10.0.1.jar
lz4-1.3.0.jar
slf4j-api-1.7.21.jar
slf4j-log4j12-1.7.21.jar
snappy-java-1.1.2.6.jar

3）修改zkEnv.sh
最后一行添加
export SERVER_JVMFLAGS=" -Djava.security.auth.login.config=/usr/local/zookeeper/conf/zk_server_jaas.con"
4）启动Zookeeper　　

kafka服务的配置

1）kafka增加认证信息：conf/kafka_server_jaas.conf
创建JAAS文件：
KafkaServer {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="admin-sec"
user_admin="admin-sec"
user_producer="prod-sec"
user_consumer="cons-sec";
};

2）配置server.properties
listeners=SASL_PLAINTEXT://主机名称:9092
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.enabled.mechanisms=PLAIN
sasl.mechanism.inter.broker.protocol=PLAIN
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer
allow.everyone.if.no.acl.found=true //当没有找到ACL配置时，允许所有的访问操作。

3）修改启动脚本 bin/kafka-server-start.sh
修改
exec $base_dir/kafka-run-class.sh kafka.Kafka "$@"
为
exec $base_dir/kafka-run-class.sh $EXTRA_ARGS -Djava.security.auth.login.config=/usr/local/kafka/config/kafka_server_jaas.conf kafka.Kafka "$@"

　　kafka客户端配置

1）创建JAAS文件：
消费者：conf/kafka-consumer-jaas.conf
KafkaClient {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="consumer"
password="cons-sec";
};
生产者：conf/kafka-producer-jaas.conf
KafkaClient {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="producer"
password="prod-sec";
};

2）修改客户端配置信息：
分别在conf/producer.properties和conf/consumer.properties添加认证机制
security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
consumer.properties中额外加入分组配置
group.id=test-group
3）修改客户端脚本指定JAAS文件加载：

生产者bin/kafka-console-producer.sh：
修改
exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleProducer "$@"
为
exec $(dirname $0)/kafka-run-class.sh -Djava.security.auth.login.config=/usr/local/kafka/config/kafka-producer-jaas.conf kafka.tools.ConsoleProducer "$@"

消费者bin/kafka-console-consumer.sh：
修改
exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleConsumer "$@"
为
exec $(dirname $0)/kafka-run-class.sh -Djava.security.auth.login.config=/usr/local/kafka/config/kafka-consumer-jaas.conf kafka.tools.ConsoleConsumer "$@"

　　进行授权

1）创建主题 test
2）增加生产权限
./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:producer --operation Write --topic test
3）配置消费权限
./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:consumer --operation Read --topic test
4）配置消费分组权限
./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:consumer --operation Read --group test-group
5）查看配置的权限
./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --list

6）取消权限
./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --remove --allow-principal User:producer --operation Write --topic test

测试
1）生产数据
./bin/kafka-console-producer-jaas.sh --topic test --broker-list 192.168.1.20:9092 --producer.config config/producer-jaas.properties

2）消费数据
./bin/kafka-console-consumer-jaas.sh --topic test --bootstrap-server 192.168.1.20:9092 --consumer.config config/consumer-jaas.properties
