官方文档
https://kafka.apache.org/documentation/#security_sasl解决方案
-
使用正确的凭证更新JAAS配置:sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="user" password="pass";
-
在代理上重置SCRAM凭证:kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config 'SCRAM-SHA-256=[password=newpass]' --entity-type users --entity-name user
-
检查代理日志以查找认证失败,确定确切的凭证不匹配。
无效尝试
常见但无效的做法:
-
90% 失败
Re-adding the same credentials in JAAS file without verifying against the broker's credential store will fail.
-
95% 失败
Disabling SASL entirely removes security, which is not acceptable in production.
