Log4J 与 Tomcat 的集成 - catalina.out 日志文件轮换

Question

我使用 log4j 版本 2 作为 Tomcat 8 的记录器，现在的问题是 catalina.out 文件不是每天旋转。我的 log4j.property 文件如下，

log4j.rootLogger = INFO, CATALINA, CONSOLE

# Define all the appenders
log4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppender
log4j.appender.CATALINA.File = ${catalina.base}/logs/catalina
log4j.appender.CATALINA.Append = true
log4j.appender.CATALINA.Encoding = UTF-8
# Roll-over the log once per day
log4j.appender.CATALINA.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout
log4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.appender.LOCALHOST = org.apache.log4j.DailyRollingFileAppender
log4j.appender.LOCALHOST.File = ${catalina.base}/logs/localhost
log4j.appender.LOCALHOST.Append = true
log4j.appender.LOCALHOST.Encoding = UTF-8
log4j.appender.LOCALHOST.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.LOCALHOST.layout = org.apache.log4j.PatternLayout
log4j.appender.LOCALHOST.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.appender.MANAGER = org.apache.log4j.DailyRollingFileAppender
log4j.appender.MANAGER.File = ${catalina.base}/logs/manager
log4j.appender.MANAGER.Append = true
log4j.appender.MANAGER.Encoding = UTF-8
log4j.appender.MANAGER.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.MANAGER.layout = org.apache.log4j.PatternLayout
log4j.appender.MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.appender.HOST-MANAGER = org.apache.log4j.DailyRollingFileAppender
log4j.appender.HOST-MANAGER.File = ${catalina.base}/logs/host-manager
log4j.appender.HOST-MANAGER.Append = true
log4j.appender.HOST-MANAGER.Encoding = UTF-8
log4j.appender.HOST-MANAGER.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.HOST-MANAGER.layout = org.apache.log4j.PatternLayout
log4j.appender.HOST-MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.appender.CONSOLE = org.apache.log4j.DailyRollingFileAppender
log4j.appender.CONSOLE.File = ${catalina.base}/logs/catalina.out
log4j.appender.CONSOLE.Append = true
log4j.appender.CONSOLE.Encoding = UTF-8
log4j.appender.CONSOLE.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern = %d [%t] %-5p %c- %m%n


# Configure which loggers log to which appenders
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost] = INFO, LOCALHOST
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager] =\
  INFO, MANAGER
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager] =\
  INFO, HOST-MANAGER

我改变了这行

log4j.appender.CONSOLE = org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.Encoding = UTF-8 log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

到

log4j.appender.CONSOLE = org.apache.log4j.DailyRollingFileAppender
log4j.appender.CONSOLE.File = ${catalina.base}/logs/catalina.out
log4j.appender.CONSOLE.Append = true
log4j.appender.CONSOLE.Encoding = UTF-8
log4j.appender.CONSOLE.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

正如 augustin ghauratto 在this link 中所建议的那样。但这对我不起作用。

我怎样才能让 catalina.out 文件每天拆分和制作新文件。

Answer 1

您误解了catalina.out 的创建方式。它不是由像 log4j 这样的日志框架处理的。它是由shell通过标准输出流的重定向创建的。

如果要旋转它，请查看Tomcat FAQ。

还有this previous answer。
