本文主要是介绍Will not attempt to authenticate using SASL (unknown error) (org，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！
由于kafka运行是通过docker镜像的方式运行的，而且zookeeper外部的客户端也可以连接上zookeeper就排除了，zookeeper的异常情况，那么剩下的只可能是kafka运行的命令出问题了，我之前的运行命令如下：
docker run -dit --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka \
-p 9092:9092 \
-e KAFKA_BROKER_ID=0 \
-e KAFKA_ZOOKEEPER_CONNECT=106.14.132.94:2181 \
-e KAFKA_ADVERTISED_HOST_NAME=106.14.132.94 \
-e KAFKA_ADVERTISED_PORT=9092 \
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://106.14.132.94:9092 \
-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 \
-v /etc/localtime:/etc/localtime \
-t wurstmeister/kafka
把监听的0.0.0.0改成服务器ip地址
docker run -dit --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka \
-p 9092:9092 \
-e KAFKA_BROKER_ID=0 \
-e KAFKA_ZOOKEEPER_CONNECT=106.14.132.94:2181 \
-e KAFKA_ADVERTISED_HOST_NAME=106.14.132.94 \
-e KAFKA_ADVERTISED_PORT=9092 \
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://106.14.132.94:9092 \
-e KAFKA_LISTENERS=PLAINTEXT://106.14.132.94:9092 \
-v /etc/localtime:/etc/localtime \
-t wurstmeister/kafka
但是还是有出错的情况：
