kerberos生成principal

## 创建principal
sudo /usr/sbin/kadmin.local -q 'addprinc -randkey zookeeper/orchome@EXAMPLE.COM'
sudo /usr/sbin/kadmin.local -q 'addprinc -randkey kafka/orchome@EXAMPLE.COM'
sudo /usr/sbin/kadmin.local -q 'addprinc -randkey clients/orchome@EXAMPLE.COM'

楼主大神好:
我的按上面配置后,启动kafka-server出现以下错误

半兽人 -> 梦中的真 1年前

认证失败了,你细致一些。
把对应的日志监控起来,来排查问题。

梦中的真 -> 半兽人 1年前

是的,应该是kafka连接zookeeper时认证出现问题,我看了kerberos的日志没有出现问题,用zkCii访问zookeeper也没有出现问题。现在可以看到有问题的日志就只有这两个了。配置已经仔细对了好多次,都从新搭建了两次,还是同样的问题,不知道是什么原因

梦中的真 -> 半兽人 1年前

看到zookeeper日志有如下提示,cnxn.saslServer is null: cnxn object did not initialize its saslServer properly,不知道是不是需要对zookeeper做什么操作

2020-01-09 10:08:34,162 [myid:] - ERROR [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2182:ZooKeeperServer@968] - cnxn.saslServer is null: cnxn object did not initialize its saslServer properly.

        at java.lang.Thread.run(Thread.java:748)

这个问题已经解决,分享一下
我原先是在/bin/zkServer.sh里添加了KAFKA_OPTS,后来在别的资料上看到有的配的名字是JVMFLAGS,改成JVMFLAGS后,重新启动就好了

楼主大神你好,按照上面的配置配置了krb,生产者和消费者都可以正常使用,但是bin/kafka-run-class.sh这个脚本却不能正常运行
再导入这个环境变量后

export KAFKA_OPTS="-Djava.security.krb5.conf=/etc/krb5.conf -Djava.security.auth.login.confi
g=/etc/kafka/kafka_client_jaas.conf"

按照网上的方法 https://blog.csdn.net/lyflyyvip/article/details/85715801 也不成功
请问楼主是有什么方法可以解决(文件路劲和topic信息都没有错误)

在用spark消费kafka的时候也遇到这个disconnected的问题,请问是那块出了问题

yz、 -> ln 2月前

我也出现了这个问题,请问解决了吗?

Masquerade 2年前

楼主您好请问kafka_client_jaas.conf配置文件内容使什么?然后我按照您的配置后可以查看topic和新建topic。但是通过命令行bin/kafka-console-producer.sh --broker-list dc-server11:6667 --topic test --producer.config config/producer.properties执行后就会出现 WARN Bootstrap broker dc-server11:6667 disconnected (org.apache.kafka.clients.NetworkClient)请问是不是我先需要新建一个 客户端的keyTab,然后写入到kafka_client_jaas.conf并引入到JVM参数,才可以?

安装上面的配置,在centos7上搭建和kerberos,并按照上面的步骤配置kafkakerberos认证。zookeeper启动成功,显示信息为:

求问这个认证失败是什么原因呀,拜托了,其他的jaas文件和properties文件和您的一样

你好,storm 消费kafka,认证不通过,storm 、kafka、zookeeper都需要认证。认证storm_jaas.conf配置如下:

你好你的问题解决了吗,我现在也是storm对接kafka, kafka和zookeeper都有kerberos认证

VIGO 2年前

请问可以动态添加用户吗?  加了用户是不是要更新keytab, 重启kafka之类的? 望解答

半兽人 -> VIGO 2年前

https://www.orchome.com/553
搜索一下“动态”

VIGO -> 半兽人 2年前

感谢回复, 搜了下,还不是很明白, 如果设置了acl, 不同用户去生产消费, 是不是需要用不同的客户端实例? producer是不是就不能使用同一个了

Fate. Fire 2年前

你好,我再kafka上设置好了sasl认证,然后再Java程序中的生产者和消费者设置了

System.setProperty("java.security.auth.login.config", "/Users/Sean/Documents/Gitrep/bigdata/kafka/src/main/resources/kafka_client_jaas.conf"); // 环境变量添加,需要输入配置文件的路径
props.put("security.protocol", "SASL_PLAINTEXT");
props.put("sasl.mechanism", "PLAIN");,现在我生产和消费报这个错Caused by: java.lang.IllegalArgumentException: Could not find a 'KafkaClient' entry in the JAAS configuration. System property 'java.security.auth.login.config' is /home/hadoop/kafka_2.11-1.1.0/config/kafka_client_jaas.conf

没有这个属性额,你注意下你的错误。

stone -> 半兽人 2年前

为什么没有这个属性呢,很多帖子都有呢

stone -> Fate. Fire 2年前

你这个目前解决没有呢,我也遇见这个问题了

我的意思是没有找到KafkaClient这个条目,在JAAS配置中。

stone -> 半兽人 2年前

我的有KafkaClietn这个条目,java程序可以读取,现在是kettle ETL工具,使用kafka consumer组件,每次都报Kafka Consumer.0 - Caused by: java.lang.IllegalArgumentException: Could not find a 'KafkaClient' entry in the JAAS configuration. System property 'java.security.auth.login.config' is C:\ProgramData\MIT\Kerberos5\kafka_client_jaas.conf

看下kafka_client_jaas.conf 文件编写的 格式对不对 client{ ;}; 注意 总共两个分号 “;”

这个是说客户端代码目前不支持。

按照上面的配置,Kafka单机没有问题,启用多台Kafka服务器,broker报错如下:
[2018-05-03 14:52:13,975] ERROR [Controller id=1, targetBrokerId=0] Connection to node 0 failed authentication due to: An error: (java.security.PrivilegedActionException: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7) - LOOKING_UP_SERVER)]) occurred when evaluating SASL token received from the Kafka Broker. Kafka Client will go to AUTHENTICATION_FAILED state. (org.apache.kafka.clients.NetworkClient)
