我想限制Tomcat日志文件夹中的标准输出文件大小。
我的问题是：
- 我需要配置额外的日志记录配置，除了
-Djava.util.logging.FileHandler.limit=25000000？ - 是否需要重新启动 Apache 服务才能生效更改？
我想在"Java"选项卡下添加"Java选项"部分，添加以下内容：-Djava.util.logging.FileHandler.limit=25000000
已经在 Java 选项部分中定义了以下参数：
-Dcatalina.home=C:Program FilesApache Software FoundationTomcat 8.0
-Dcatalina.base=C:Program FilesApache Software FoundationTomcat 8.0
-Djava.endorsed.dirs=C:Program FilesApache Software FoundationTomcat 8.0endorsed
-Djava.io.tmpdir=C:Program FilesApache Software FoundationTomcat 8.0temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:Program FilesApache Software FoundationTomcat 8.0conflogging.properties

Tomcat使用java.util.logging.ConsoleHandler(不是java.util.logging.FileHandler)记录到错误文件描述符，将所有内容发送到System.err。因此，无法限制日志的大小。
但是，您可以在prunsrv中(通常重命名为tomcat8.exe)：
-
通过将
--StdOutput和--StdError设置为空字符串，禁用stdout/stderr重定向到任何文件。与Tomcat一起分发的默认logging.properties文件也会将所有内容记录到catalina.<date>.log，每天轮换一次，因此Tomcat的日志不会丢失。 -
将
--StdOutput和--StdError选项设置为auto，这应该每天轮换它们，尽管我没有测试并且似乎还没有实现[1]。
您也可以在图形界面prunmgr(通常重命名为tomcat8w.exe)中更改此设置。
备注：如果禁用stdout/stderr到文件的重定向，则还应通过修改logging.properties来禁用ConsoleHandler：
.handlers = 1catalina.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler
自：
.handlers = 1catalina.org.apache.juli.AsyncFileHandler
还要检查您的 Web 应用程序是否不使用除java.util.logging以外的其他日志记录框架，并修改日志记录配置(log4j.propertiesLog4j 1.x 等)，以便不记录任何内容到标准输出/错误中。
