启动 tomcat 导致 catalina.out 中出现“java.io.FileNotFoundException: ../logs/dc.log (没有这样的文件或目录)”

多年来，我一直将此视为 tomcat 应用程序的一部分，现在我已经完成了调查它的步骤，但我找不到原因。这是我在运行各种应用程序的 CentOS 服务器上启动 tomcat 时看到的内容：

它从未导致任何问题，但我在服务器上的任何配置文件中都找不到“dc.log”，更不用说 tomcat 了，所以我不知道是什么导致了这个错误。谷歌搜索没有得到任何结果，这让我难以置信。我该如何找到它？

答案1

提示在异常中：log4j 正在抱怨。假设您检查的配置文件全部在 中$TOMCAT_HOME/conf，您将需要深入研究 部署的属性文件ROOT.war。

grep -r dc.log webapps是获得所需内容的最懒惰的方法。

（换句话说，责怪你的开发人员。）
