我试着在运行kafka的计算示例（centos7）上的github上按照步骤设置kafka导出器。
当我运行下面的命令时，我得到了“error init kafka client”：

/opt/kafkaexporter/kafka_exporter --kafka.server=kafka1:9092 --kafka.version="2.11.0" --tls.enabled  --log.enable-sarama

非常感谢任何关于在运行kafka的计算机示例上运行kafka\u导出器的建议。
先谢谢你，
控制台输出：

/opt/kafkaexporter/kafka_exporter --kafka.server=kafka1:9092 --kafka.version="2.11.0" --tls.enabled  --log.enable-sarama
