我的kafka客户客户端无法在Mac上运行，为什么？

Question

嗨：我是kafka的新手，我按照以下步骤在Mac上安装和初始化kafka：

brew install kafka

我可以看到配置文件是：

/usr/local/etc/kafka/server.properties
/usr/local/etc/kafka/zookeeper.properties

开始kafka

kafka-server-start /usr/local/etc/kafka/server.properties &

创建一个名为“测试”的主题

kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

我可以列出它：

kafka-topics --list --zookeeper localhost:2181

在一个终端中启动生产者并输入一些文本：

kafka-console-producer.sh --broker-list localhost:9092 --topic test 
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/x/Documents/zk/server1/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/local/Cellar/kafka/2.0.0/libexec/libs/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

开始消费

kafka-console-consumer --bootstrap-server localhost:9092 --topic test --from-beginning
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/x/Documents/zk/server1/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

无论我在生产者终端中输入什么，消费者都不会打印任何内容。如何解决此问题，我错过了什么吗？

从https://www.apache.org/dyn/closer.cgi?path=/kafka/2.0.0/kafka_2.11-2.0.0.tgz

下载apache Kafka

在任何位置解压缩并在所有终端上执行以下命令，以便执行以下命令，否则您可以替换命令中的安装路径并执行。

export kafka=<location-of-unzipped-directory>

1. 通过在上述终端$kafka/bin/zookeeper-server-start.sh $kafka/config/zookeeper.properties中执行来运行Zookeeper
2. 运行kafka经纪人：$kafka/bin/kafka-server-start.sh $kafka/config/server.properties
3. 运行生产者：$kafka/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
4. 运行消费者：$kafka/bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning
5. 在生产者中键入可以在消费者中看到输出的任何内容

代替记住命令，可以在.bashrc或.zshrc中添加以下命令

export kafka="/Users/mac-user/standalone/kafka_2.11-2.0.0"
alias startkafka="$kafka/bin/kafka-server-start.sh $kafka/config/server.properties"
alias startzoo="$kafka/bin/zookeeper-server-start.sh $kafka/config/zookeeper.properties"
alias stopkafka="$kafka/bin/kafka-server-stop.sh"
alias stopzoo="$kafka/bin/zookeeper-server-stop.sh"
