在 Windows 上重命名 Kafka 日志文件时出现 log4J（1.2.17 版本）问题

Question

我在 Windows 平台上运行 Kafka 2.8.0 版，而该平台又使用 log4J 1.2.17 版。 我面临以下log4j:ERROR 无法重命名由 Zookeeper 和 Kafka 服务器上的 Log4j 引起的问题。 请让我知道如何解决这个问题？

动物园管理员日志：

[ERR] [ZooKeeper] log4j:ERROR Failed to rename [C:\kafka-2.8.0/logs/controller.log] to [C:\kafka-2.8.0/logs/controller.log.2021-07-21-00].

Kafka 服务器日志：

log4j:ERROR Failed to rename [C:\kafka-2.8.0/logs/controller.log] to [C:\kafka-2.8.0/logs/controller.log.2021-07-21-00].

注意：这个问题经常发生在 controller.log 和 server.log 文件中

下面是我目前使用的 log4J 属性文件，

log4j.properties 文件：

正如@OneCricketeer 建议的那样，您应该将路径从/更改为\\\\

在配置文件中使用 2 个反斜杠：

在C:\\kafka\\config\\zookeeper.properties 中：

dataDir=c:\\kafka\\zookeeper

并在C:\\kafka\\config\\server.properties 中：

log.dirs=c:\\kafka\\kafka-logs

也去C:\\kafka\\config\\log4j.properties

无论你在哪里看到这样的东西：

log4j.appender.kafkaAppender.File=${kafka.logs.dir}/server.log

改成这样：

log4j.appender.kafkaAppender.File=${kafka.logs.dir}\\server.log

这些都是您应该更改它的地方：

Line 26: log4j.appender.kafkaAppender.File=${kafka.logs.dir}\\server.log
Line 32: log4j.appender.stateChangeAppender.File=${kafka.logs.dir}\\state-change.log
Line 38: log4j.appender.requestAppender.File=${kafka.logs.dir}\\kafka-request.log
Line 44: log4j.appender.cleanerAppender.File=${kafka.logs.dir}\\log-cleaner.log
Line 50: log4j.appender.controllerAppender.File=${kafka.logs.dir}\\controller.log
Line 56: log4j.appender.authorizerAppender.File=${kafka.logs.dir}\\kafka-authorizer.log
