apache-kafka - 尝试启动 Zookeeper 服务器时出错 - Confluent 设置

问题描述

我正在尝试在 Ubuntu 16.04 上设置 Confluent-4.1.1。为了启动 ZooKeeper 服务器，我按照本教程./bin/zookeeper-server-start ./etc/kafka/zookeeper.properties.txt从 Confluent 的根目录运行。 出现的错误是- 

log4j:ERROR Could not read configuration file from URL [file:./bin/../config/log4j.properties].

我是卡夫卡的新手，我不知道这意味着什么。解决此问题的任何帮助将不胜感激。

解决方案

您关注的链接只是 Apache Kafka，而不是 Confluent，尽管它们至少在启动 Zookeeper 时应该类似地工作。

如果你已经下载了 Confluent 发行版，并且想要一个单节点集群，你可以使用Confluent CLI

要启动 Zookeeper、Kafka 和 Confluent 平台的其余部分，请运行

./bin/confluent start

否则，Zookeeper 启动脚本不使用 txt 文件，它可能无法检测到您提取 tarball 的位置，因此您可以像使用普通软件包一样使用 apt
