tomcat 分割catalina日志【log4j配置方式】

工具/原料

• log4j-1.2.16.jar
• tomcat-juli-adapters.jar
• tomcat-juli.jar
  *下载地址：http://www.apache.org/dist/tomcat在对应版本中的bin/extras路径下

修改相关配置文件

1. 修改${catalina.home}/conf/context.xml
   修改：为为只有这样才能完全的把tomcat的stdout给接管过来。
2. 建立log4j.properties

log4j.rootLogger=INFO, CATALINA
# Define all the appenders
log4j.appender.CATALINA=org.apache.log4j.DailyRollingFileAppender
log4j.appender.CATALINA.File=/applog/tomcat/catalina.log
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
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=/applog/tomcat/localhost.log
log4j.appender.LOCALHOST.Append=true
log4j.appender.LOCALHOST.Encoding=UTF-8
log4j.appender.LOCALHOST.DatePattern='.'yyyy-MM-dd
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=/applog/tomcat/manager.log
log4j.appender.MANAGER.Append=true
log4j.appender.MANAGER.Encoding=UTF-8
log4j.appender.MANAGER.DatePattern='.'yyyy-MM-dd
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=/applog/tomcat/host-manager.log
log4j.appender.HOST-MANAGER.Append=true
log4j.appender.HOST-MANAGER.Encoding=UTF-8
log4j.appender.HOST-MANAGER.DatePattern='.'yyyy-MM-dd
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]=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]=\

3. 复制替换${catalina.home}/bin下的tomcat-juli.jar
4. 复制log4j-1.2.16.jar、tomcat-juli-adapters.jar和log4j.properties 到tomcat的lib下
5. 修改bin/catalina.sh
   a. 屏蔽或删除如下内容：
   (1) if [ -z "$CATALINA_OUT" ] ; then
   CATALINA_OUT=$CATALINA_BASE/logs/catalina.out
   fi
   (2) touch "$CATALINA_OUT"
   (3) >> "$CATALINA_OUT" 2>&1 "&" (两处)
   b. 修改org.apache.catalina.startup.Bootstrap "$@" start \ 内容 （两处）
   修改为：org.apache.catalina.startup.Bootstrap "$@" start&\
6. 修改conf/server.xml中localhost_access_log日志路径
   prefix="localhost_access_log." suffix=".txt"
   pattern="%h %l %u %t "%r" %s %b" />
7. 删除conf/logging.properties文件
8. 启动tomcat。
