由於tomcat catalina.out日誌不會自動分割，

一、日誌分割所需包在附近中

1、 壓縮包中有三個jar包：

    log4j-1.2.16.jar 

    tomcat-juli-adapters.jar

    tomcat-juli.jar

   說明：如果不是tomcat7版本，請去官網下載對應版本的tomcat-juli.jar，tomcat-juli-adapters.jar類包，

         下載地址： http://www.apache.org/dist/tomcat   在對應版本中的 bin/extras路徑下

 

二、修改相關配置檔案

1、 修改${catalina.home}/conf/context.xml

修改：<Context >為<Context  swallowOutput="true" >只有這樣才能完全的把tomcat的stdout給接管過來。

2、 複製log4j-1.2.16.jar和tomcat-juli-adapters.jar 到tomcat的lib下

3、 複製tomcat-juli.jar到${catalina.home}/bin下，在該目錄會存在該檔案，覆蓋即可

4、 建立log4j.properties,並把其放到到tomcat的/lib下

Log4j.properties的內容如下：相關引數根據需要可以相應修改

log4j.rootLogger=INFO, CATALINA

# Define all the appenders

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

log4j.appender.CATALINA.File=/home/richmail/logs/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=/home/richmail/logs/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=/home/richmail/logs/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=/home/richmail/logs/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]=INFO, HOST-MANAGER

 

5. 修改bin/catalina.sh

  a. 遮蔽或刪除如下內容：

       (1) if [ -z "$CATALINA_OUT" ] ; then

              CATALINA_OUT=$CATALINA_BASE/logs/catalina.out

            fi

       (2) touch "$CATALINA_OUT"

  

       (3) >> "$CATALINA_OUT" 2>&1 "&"  (兩處)

  b. 修改org.apache.catalina.startup.Bootstrap "[email protected]" start \   內容 （兩處）

     修改為：org.apache.catalina.startup.Bootstrap "[email protected]" start  & \

         

6. 修改conf/server.xml中localhost_access_log日誌路徑

<Valve className="org.apache.catalina.valves.AccessLogValve" directory=" /home/richmail/logs/tomcat "

               prefix="localhost_access_log." suffix=".txt"

               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

7. 刪除 conf/logging.properties  檔案

8. 啟動tomcat。
