Tomcat - 标准输出文件非常大

Question

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：

1. 我需要配置额外的日志配置，除了 -Djava.util.logging.FileHandler.limit=25000000?
2. 是否需要重启 apache 服务才能使更改生效？

我想在 Java 选项卡下添加，在 Java 选项部分添加以下内容： -Djava.util.logging.FileHandler.limit=25000000

已经在 J​​ava 选项部分定义了以下参数：

-Dcatalina.home=C:\Program Files\Apache Software Foundation\Tomcat 8.0
-Dcatalina.base=C:\Program Files\Apache Software Foundation\Tomcat 8.0
-Djava.endorsed.dirs=C:\Program Files\Apache Software Foundation\Tomcat 8.0\endorsed
-Djava.io.tmpdir=C:\Program Files\Apache Software Foundation\Tomcat 8.0\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\Program Files\Apache Software Foundation\Tomcat 8.0\conf\logging.properties

Answer 1

Tomcat 使用java.util.logging.ConsoleHandler（不是java.util.logging.FileHandler）将所有内容发送到System.err 记录到错误文件描述符。因此无法限制日志的大小。

但是你可以在prunsrv（通常重命名为tomcat8.exe）：

1. 通过将--StdOutput 和--StdError 设置为空字符串来禁用stdout/stderr 到任何文件的重定向。与 Tomcat 一起分发的默认 logging.properties 文件还将所有内容记录到 catalina.<date>.log，该文件每天轮换一次，因此 Tomcat 的日志不会丢失。

2. 将--StdOutput 和--StdError 选项设置为auto，这应该每天轮换它们，尽管我没有测试它doesn't seem to be implemented yet^[1]。

您也可以在图形界面 prunmgr 中更改此设置（通常重命名为 tomcat8w.exe）。

备注：如果您禁用stdout/stderr 到文件的重定向，您还应该通过修改logging.properties 来禁用ConsoleHandler：

.handlers = 1catalina.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler

到：

.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 之外的其他日志记录框架，并修改日志记录配置（log4j.properties 用于 Log4j 1.x 等），以便没有任何内容记录到标准输出/错误中。
