本文主要是介绍kerberos kafka 问题解决，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
修改 kafka界面 security.inter.broker.protocol SASL_PLAINTEXT
登录添加用户生成keytab
kadmin.local
add_principal flink/master@AQ.COM
add_principal flink/worker-1@AQ.COM
add_principal flink/worker-2@AQ.COM
生成文件
xst -k /usr/local/keytab/flink/flink-master.keytab flink/master@AQ.COM
xst -k /usr/local/keytab/flink/flink-worker-1.keytab flink/worker-1@AQ.COM
xst -k /usr/local/keytab/flink/flink-worker-2.keytab flink/worker-2@AQ.COM
或者
kadmin.local -q "xst -k /usr/local/keytab/flink/flink-master.keytab flink/master@AQ.COM"
keytab合并
ktutil
rkt /usr/local/keytab/flink/flink-master.keytab
rkt /usr/local/keytab/flink/flink-worker-1.keytab
rkt /usr/local/keytab/flink/flink-worker-2.keytab
wkt /usr/local/keytab/flink/flink.keytab
查看keytab
klist -ket user.keytabkinit登录与kadmin.local不能同时存在
kinit -kt /usr/local/keytab/flink/flink-master.keytab flink/master@AQ.COM
删除认证缓存
kdestroy
kafka生产消费
1.客户端操作kafka生产消费需要jaas.conf以及各自的生产消费的配置文件
2.代码需要设置两个变量
jaas.conf
KafkaClient{com.sun.security.auth.module.Krb5LoginModule requiredkeyTab="/usr/local/keytab/flink/flink.keytab"principal="flink/master@AQ.COM"useKeyTab=trueuseTicketCache=true;
};
Client{com.sun.security.auth.module.Krb5LoginModule requiredkeyTab="/usr/local/keytab/flink/flink.keytab"principal="flink/master@AQ.COM"useKeyTab=trueuseTicketCache=true;
};
KafkaServer{com.sun.security.auth.module.Krb5LoginModule requiredkeyTab="/usr/local/keytab/flink/flink.keytab"principal="flink/master@AQ.COM"useKeyTab=trueuseTicketCache=true;
};
producer.properties
security.protocol=SASL_PLAINTEXT
sasl.mechanism=GSSAPI
sasl.kerberos.service.name=kafka
consumer.properties
security.protocol=SASL_PLAINTEXT
sasl.mechanism=GSSAPI
sasl.kerberos.service.name=kafka
group.id=testClient
客户端消费命令
export KAFKA_OPTS="-Djava.security.auth.login.config=/usr/local/keytab/kafka/jaas.conf"

yml配置
kafka:bootstrap-servers: master:9092,worker-2:9092producer:#procedure要求leader在考虑完成请求之前收到的确认数，用于控制发送记录在服务端的持久化，其值可以为如下：#acks = 0 如果设置为零，则生产者将不会等待来自服务器的任何确认，该记录将立即添加到套接字缓冲区并视为已发送。在这种情况下，无法保证服务器已收到记录，并且重试配置将不会生效（因为客户端通常不会知道任何故障），为每条记录返回的偏移量始终设置为-1。#acks = 1 这意味着leader会将记录写入其本地日志，但无需等待所有副本服务器的完全确认即可做出回应，在这种情况下，如果leader在确认记录后立即失败，但在将数据复制到所有的副本服务器之前，则记录将会丢失。#acks = all 这意味着leader将等待完整的同步副本集以确认记录，这保证了只要至少一个同步副本服务器仍然存活，记录就不会丢失，这是最强有力的保证，这相当于acks = -1的设置。#可以设置的值为：all, -1, 0, 1acks: 1key-serializer: org.apache.kafka.common.serialization.StringSerializervalue-serializer: org.apache.kafka.common.serialization.StringSerializer#=============== provider =======================# 写入失败时，重试次数。当leader节点失效，一个repli节点会替代成为leader节点，此时可能出现写入失败，# 当retris为0时，produce不会重复。retirs重发，此时repli节点完全成为leader节点，不会产生消息丢失。retries: 0consumer:group-id: mysqltestUserBehaviorGroupenable-auto-commit: trueauto-offset-reset: latestkey-serializer: org.apache.kafka.common.serialization.StringSerializervalue-serializer: org.apache.kafka.common.serialization.StringSerializerjaas:enabled: trueproperties:security.protocol: SASL_PLAINTEXTsasl.kerberos.service.name: kafkajava flink 消费时候getKerberosJaas就好
