tomcat日志处理

tomcat使用log4j分割

官方文档

下载tomcat-juli-adapters.jar和tomcat-juli.jar 和log4j.jar

将tomcat-juli-adapters.jar和log4j.jar拷贝到 tomcat目录\lib下

将tomcat-juli.jar放到 tomcat目录\bin下

删除tomcat/conf下的logging.properties

在tomcat/lib下创建log4j.properties文件(多节点情况下请把${catalina.base}改为实际的tomcat目录)

log4j.rootLogger = INFO, CATALINA
 
# Define all the appenders
#log4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppender
log4j.appender.CATALINA = org.apache.log4j.RollingFileAppender
log4j.appender.CATALINA.File = ${catalina.base}/logs/catalina.out
log4j.appender.CATALINA.Append = true
log4j.appender.RollingFile.ImmediateFlush=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.MaxFileSize=1MB
log4j.appender.CATALINA.MaxBackupIndex=10
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
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost] = DEBUG, LOCALHOST
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager] = DEBUG, MANAGER
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager] = DEBUG, HOST-MANAGER
log4j.logger.org.apache.catalina.core = DEBUG
log4j.logger.org.apache.catalina.session = DEBUG

注释掉catalina.sh的自动生成catalina.out

if [ -z "$CATALINA_OUT" ] ; then
  #CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
  CATALINA_OUT=/dev/null
fi

Tomcat使用定时任务分割

编写shell脚本,放在tomcat/bin下,在cron中自动执行

#!/bin/bash

cd  `dirname $0`
d=`date +%Y%m%d`
d7=`date -d'7 day ago' +%Y%m%d`

cd  ../logs/

cp catalina.out catalina.out.${d}
echo "" > catalina.out 
rm -rf catalina.out.${d7}
