tomcat log 配置解决catalina.out文件过大问题

Tomcat7.0.55下使用Log4j 接管 catalina.out 日志文件生成方式，按天存放，解决catalina.out日志文件过大问题

1. 准备jar包：

    log4j-1.2.17.jar （从 http://www.apache.org/dist/logging/log4j/1.2.17/ 下载）

    tomcat-juli.jar, tomcat-juli-adapters.jar （从http://www.apache.org/dist/tomcat/tomcat-7/v7.0.55/bin/extras/下载，根据你的Tomcat版本选择对应的分支）

2. 将上面的三个jar包拷贝到 Tomcat 的 lib 目录下；

3. 将 tomcat-juli.jar 拷贝到 Tomcat 的 bin 目录下，替换原有的jar包；

4. 修改 Tomcat 的 conf/context.xml 文件，将<Context>为<Context swallowOutput="true">

  （增加 swallowOutput="true" 的属性配置，只有这样才能完全的把tomcat的stdout给接管过来。这一步很关键 在官网及网上找了许多资料都没有提及。）；

5. 删除 Tomcat 的 conf/logging.properties 文件（或者重命名-建议）；

6. 在 Tomcat 的 lib 目录下创建 log4j.properties 文件：

 

log4j.rootLogger=INFO, CATALINA

log4j.logger.org.apache=INFO, CATALINA

log4j.logger.org.hibernate=WARN, CATALINA

log4j.logger.org.springframework=WARN, CATALINA

 

# Define all the appenders

log4j.appender.CATALINA=org.apache.log4j.DailyRollingFileAppender

log4j.appender.CATALINA.File=${catalina.base}/logs/catalina.out

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.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

 

# Configure which loggers log to which appenders

# 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]=\
