在Linux系统下，tomcat日志catalina.out并不会像window系统下，按日期进行重写备份，因此在Linux系统下会造成日志文件过大的情况，本文介绍采用 cronolog工具进行如在window下的效果，做到按日期自动分割日志，过程如下：
1.在Linux安装cronolog，本文中采用的是cronolog-1.6.2版本
[root@Test src]# tar zxvf cronolog-1.6.2.tar.gz
[root@Test cronolog-1.6.2]# ./configure
[root@Test cronolog-1.6.2]# make && make install
2.找到tomcat下catalina.sh文件，编辑修改
[root@Test bin]# vi catalina.sh
shift touch "$CATALINA_OUT" if [ "$1" = "-security" ] ; then if [ $have_tty -eq 1 ]; then echo "Using Security Manager" fi shift "$_RUNJAVA" "$LOGGING_CONFIG" $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 >> "$CATALINA_OUT" 2>&1 & else "$_RUNJAVA" "$LOGGING_CONFIG" $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 & 修改为 shift touch "$CATALINA_OUT" if [ "$1" = "-security" ] ; then if [ $have_tty -eq 1 ]; then echo "Using Security Manager" fi shift "$_RUNJAVA" "$LOGGING_CONFIG" $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 |/usr/local/sbin/cronolog "$CATALINA_BASE"/logs/catalina.%Y-%m-%d.out >> /dev/null 2>&1 & else "$_RUNJAVA" "$LOGGING_CONFIG" $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 "$@" start |/usr/local/sbin/cronolog "$CATALINA_BASE"/logs/catalina.%Y-%m-%d.out >> /dev/null 2>&1 &
3.重新启动tomcat，效果如下：
