<转>tomcat下catalina.out日志文件分割

原链接：http://baalwolf.iteye.com/blog/1464093

tomcat默认使用java.util.logging记录日志，默认只记录tomcat的日志，不记录应用的日志。tomcat支持采用log4j进行日志记录，配置方法如下：
1.更新最新的tomcat_juli.jar包到./bin/目录下；
2.拷贝log4j.jar,lo4j.properties到./lib目录下;
3.删除./conf/logging.properties
4.重启

log4j配置样本

log4j.rootLogger=INFO,CATALINA  
log4j.logger.com.danga.MemCached.MemCachedClient=WARN,CATALINA   
#log4j.appender.CONSOLE = org.apache.log4j.ConsoleAppender  
#log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout  
#log4j.appender.CONSOLE.encoding = UTF-8  
#log4j.appender.CONSOLE.layout.conversionPattern =[%p-%d{yyyy/MM/dd/HH\:mm\:ss}]%c{1}.(%L) - %m%n   
  
  
# Define CATALINA appenders  
log4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppender  
log4j.appender.CATALINA.file = ${catalina.base}/logs/catalina.out  
log4j.appender.CATALINA.DatePattern ='.'yyyy-MM-dd  
log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout  
log4j.appender.CATALINA.layout.conversionPattern = [%p-%d{yyyy/MM/dd/HH\:mm\:ss}]%c{1}.(%L) - %m%n   
log4j.appender.CATALINA.append = true  

lo4j自动在午夜切割catalina.out成catalina.out.2011-03-07
