Question

我正在尝试在kafka上运行Ubuntu服务器。当我运行此命令时：

> bin/zookeeper-server-start.sh config/zookeeper.properties

我没有得到任何东西，当我尝试通过此命令运行Kafka服务器时：

> bin/kafka-server-start.sh config/server.properties

我收到此错误。

Answer 1

Kafka输出表明zookeeper没有启动。

如果zookeeper-server-start.sh没有输出，请检查zookeeper.log。如果这没有帮助，请尝试使用ps查找zookeeper java进程，例如：

ps -elf | grep zookeeper

如果它正在运行，您可以使用进程的PID来获取线程转储或附加调试器以查看它所处的位置。希望有所帮助。
