安装过程如下：
下载（最新版本）
# wget http://cronolog.org/download/cronolog-1.6.2.tar.gz
2、解压缩
# tar zxvf cronolog-1.6.2.tar.gz
3、进入cronolog安装文件所在目录
# cd cronolog-1.6.2
4、运行安装
# ./configure
# make
# make install
5、查看cronolog安装后所在目录（验证安装是否成功）
# which cronolog
一般情况下显示为：/usr/local/sbin/cronolog
要想分割tomcat7的catalina.out，需作如下工作：
进入Tomcat的bin目录，打开catalina.sh文件，一般我们修改下面行中的内容（做好用root用户），
（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
