安装编译
1. 下载安装 cronolog，它的主页 http://cronolog.org. 下载的是源码，安装过程就是 ./configure, make, make install，
最后一步可直接把 src/cronolog 执行文件拷入到某个适合的目录，如 /usr/local/sbin/ 目录。
2.编辑catalina.sh
1、安装cronolog，路径为：/usr/local/sbin/cronolog
2、修改bin/catalina.sh文件的两处地方，标红的为修改的内容，具体如下：
（1）if [ -z "$CATALINA_OUT" ] ; then
CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
fi
改为：
if [ -z "$CATALINA_OUT" ] ; then
CATALINA_OUT="$CATALINA_BASE"/logs/catalina.%Y-%m-%d.out
fi
（2）touch "$CATALINA_OUT"
if [ "$1" = "-security" ] ; then
if [ $have_tty -eq 1 ]; then
echo "Using Security Manager"
fi
shift
eval \"$_RUNJAVA\" \"$LOGGING_CONFIG\" $LOGGING_MANAGER $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 \
>> "$CATALINA_OUT" 2>&1 "&"
else
eval \"$_RUNJAVA\" \"$LOGGING_CONFIG\" $LOGGING_MANAGER $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_OUT" 2>&1 "&"
fi
if [ ! -z "$CATALINA_PID" ]; then
echo $! > "$CATALINA_PID"
fi
改为：
# touch "$CATALINA_OUT"
if [ "$1" = "-security" ] ; then
if [ $have_tty -eq 1 ]; then
echo "Using Security Manager"
fi
shift
eval \"$_RUNJAVA\" \"$LOGGING_CONFIG\" $LOGGING_MANAGER $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 2>&1 \
| /usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null &
else
eval \"$_RUNJAVA\" \"$LOGGING_CONFIG\" $LOGGING_MANAGER $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 "$@" start 2>&1 \
| /usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null &
fi
if [ ! -z "$CATALINA_PID" ]; then
echo $! > "$CATALINA_PID"
fi
