使用Kafka-acls授权时报错InvalidACL for kafka-acl解决方法

给Kafka Topic 授权读写操作，使用 kafka-acls

之前，我在CentOS上部署Kafka服务，使用各种命令都是正常的。

./kafka-acls.sh --authorizer-properties zookeeper.connect=localhost:2181  --list

但是最近，我开始使用Docker部署Kafka服务，结果就出现了各种问题。docker-compose.yml代码如下

version: '3.1'

  zookeeper:
    image: confluentinc/cp-zookeeper:5.1.1

      KAFKA_MANAGER_AUTH_ENABLED: 'true'

      KAFKA_MANAGER_PASSWORD: secretpassword

我进入到Kafka容器中，想要跑授权命令。

# 进入kafka容器
$ docker exec -it kafka bash
$ cd /usr/bin/

# 查看授权列表
$ ./kafka-acls --authorizer-properties zookeeper.connect=zookeeper:2181/kafka --list

结果却看到了如下错误信息。

Error while executing ACL command: KeeperErrorCode = InvalidACL for /kafka-acl

        at kafka.admin.AclCommand.main(AclCommand.scala)

我开始以为是Zookeeper的问题，比较原来的服务器上zookeeper 记录和docker中的zookeeper 没有发现任何异常， 于是，我开始各种查询资料和参考命令行参数，终于发现问题所在——请求时没有带授权信息。 那么，要怎么样带上授权信息呢？这里有一个重要的参数：--command-config。官网上使用一个文件名为adminclient-configs.conf的配置文件，可是我在GitHub上找了半天也没找到啊！

最后，好心的chatgpt帮我找到了这个神秘的配置文件，并给出了配置内容。感谢chatgpt！配置如下

# /etc/kafka/adminclient-configs.conf

bootstrap.servers=localhost:9092

security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="admin" password="secretpassword";

所以 正确的使用 kafka-acls 的命令如下

# 查看授权列表
$ /usr/bin/kafka-acls --bootstrap-server localhost:9092 --command-config /etc/kafka/adminclient-configs.conf --list

# 查看某个topic授权
$ /usr/bin/kafka-acls --bootstrap-server localhost:9092 --command-config /etc/kafka/adminclient-configs.conf --list --topic topicName

# 给topic设置某个IP的读权限
$ /usr/bin/kafka-acls --bootstrap-server localhost:9092 --command-config /etc/kafka/adminclient-configs.conf --add --allow-principal User:'*' --allow-host 39.39.39.39  --operation Read --topic topicName

现在，我终于可以正常授权了！如果你也遇到了类似的问题，可以试试我的方法哦。

总之，学习过程中遇到问题很正常，重要的是我们要勇于面对，不断探索，最终解决问题。加油！（chatgpt帮忙整理出的文章，大家凑活看吧）
