tomcat 使用log4j進行日誌分割

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，         ：http://www.apache.org/dist/tomcat  在對應版本中的bin/extras路徑下 二、修改相關設定檔
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：相關參數根據需要可以相應修改
log4j.rootLogger=INFO, CATALINA

5. 修改bin/catalina.sh  a. 屏蔽或刪除如下內容：      (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 "$@" start \   內容 （兩處）
     修改為：org.apache.catalina.startup.Bootstrap "$@" 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。
