apache-kafka - Kafka - 架构注册表不可用

Question

我下载了 Confluent Platform(在本地笔记本电脑 MacOS 上)并按照说明启动 kafka: https://docs.confluent.io/current/schema-registry/docs/intro.html

~/kafka/confluent-4.0.0/bin » confluent start schema-registry                                                                                                                                                                                               dnk306@9801a7a5b33d

通过查看上面的模式注册表似乎已启动并正在运行。如何检查是否真的在运行？

curl http://localhost:8081
curl: (7) Failed to connect to localhost port 8081: Connection refused

Answer 1

首先，您需要测试架构注册表是否仍在运行。为此，您需要运行

confluent status schema-registry

然后，您可以检查服务日志并查看是否报告了任何ERROR(以获取日志文件的最后 100 行):

confluent log schema-registry -n 100 -f

如果您确保实例已启动并运行且未报告任何错误，请尝试获取所有主题

curl -X GET http://localhost:8081/subjects
