加入kerberos 之后用普通命令行就无法直接操作kafka和zk了 需要增加几个文件

首先添加kafka的环境文件

KafkaClient {
   com.sun.security.auth.module.Krb5LoginModule required
   useKeyTab=true
   storeKey=true
   keyTab="/var/lib/keytab/kafka.keytab"
   principal="kafka@TEST.COM";
};

需要修改的就keytab位置和域

启动producer  consumer  需要另外一个文件

[root@master keytab]# cat producer.properties 
security.protocol=SASL_PLAINTEXT
sasl.mechanism=GSSAPI
sasl.kerberos.service.name=kafka


[root@master keytab]# cat consumer.properties 
security.protocol=SASL_PLAINTEXT
sasl.mechanism=GSSAPI
sasl.kerberos.service.name=kafka
group.id=test-consumer-group

 然后命令行启动即可

Could not login: the client is being asked for a password, but the Kafka client code does not currently support obtaining a password from the user. not available to garner  authentication information from the user
这个报错可以这样清空一下缓存再试试
kdestroy 
kinit -kt /var/lib/keytab/kafka.keytab kafka


export KAFKA_OPTS="-Djava.security.auth.login.config=/var/lib/keytab/kafka_jaas.conf"   

kafka-console-producer --broker-list master.test.com:9092 --topic  test1  --producer.config /var/lib/keytab/producer.properties 

consmer改一下对应的命令就行

kafka-console-consumer --topic test1 --from-beginning --bootstrap-server master:9092 --consumer.config /var/lib/keytab/consumer.properties

from-bgeinning主要是用来测试的  具体情况可加可不加

连接zk也需要同样的一个配置文件 

编写jaas-zk-keytab.conf文件

Client {
   com.sun.security.auth.module.Krb5LoginModule required
   useKeyTab=true
   keyTab="/root/hbasenew.keytab"
   storeKey=true
   useTicketCache=false
   principal="hbase@RSD.COM";
};

将jaas-zk-keytab.conf加载到环境变量

export CLIENT_JVMFLAGS="-Djava.security.auth.login.config=jaas-zk-keytab.conf"

 zookeeper-client -server master:2181

连接客户端时候一定要用-server参数指定zookeeper节点，不然连接不上

不行就也kinit 一下 再连接
