在Linux下Tomcat生成日志时不按日期生成，这样日志会越来越大，查看也不方便，手工去备份日志又很麻烦，可以修改catalina.sh文件，以达到效果。
方法很简单，找到以下代码，修改如下（注意红色字体总分）：
?
? shift
? touch “$CATALINA_BASE”/logs/catalina`date +%Y%m%d`.out
? if [ “$1” = “-security” ] ; then
??? echo “Using Security Manager”
??? shift
??? “$_RUNJAVA” $JAVA_OPTS $CATALINA_OPTS \
????? -Djava.endorsed.dirs=”$JAVA_ENDORSED_DIRS” -classpath “$CLASSPATH” \
????? -Djava.security.manager \
????? -Djava.security.policy==”$CATALINA_BASE”/conf/catalina.policy \
????? -Dcatalina.base=”$CATALINA_BASE” \
????? -Dcatalina.home=”$CATALINA_HOME” \
????? -Djava.io.tmpdir=”$CATALINA_TMPDIR” \
????? org.apache.catalina.startup.Bootstrap “$@” start \
????? >> “$CATALINA_BASE”/logs/catalina`date +%Y%m%d`.out 2>&1 &
????? if [ ! -z “$CATALINA_PID” ]; then
??????? echo $! > $CATALINA_PID
????? fi
? else
??? “$_RUNJAVA” $JAVA_OPTS $CATALINA_OPTS \
????? -Djava.endorsed.dirs=”$JAVA_ENDORSED_DIRS” -classpath “$CLASSPATH” \
????? -Dcatalina.base=”$CATALINA_BASE” \
????? -Dcatalina.home=”$CATALINA_HOME” \
????? -Djava.io.tmpdir=”$CATALINA_TMPDIR” \
????? org.apache.catalina.startup.Bootstrap “$@” start \
????? >> “$CATALINA_BASE”/logs/catalina`date +%Y%m%d`.out 2>&1 &
????? if [ ! -z “$CATALINA_PID” ]; then
??????? echo $! > $CATALINA_PID
????? fi
? fi
