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)

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
