不管是测试环境还是生产环境都需要对tomcat的日志进行切割，按天，按小时等等。
1 安装cronolog
1[root@app_51 ~]$ yum install -y cronolog
2[root@app_51 ~]$ which cronolog
3/usr/sbin/cronolog
2 修改tomcat的catalina.sh
1 [ghl@app_51 ~]$ cd /home/ghl/tomcat/apache-tomcat-8.5.37/bin/
2 [ghl@app_51 bin]$ cp catalina.sh catalina.sh.bak
3 #需要将第453-491的代码，直接替换成下面的
4 shift
5 #touch "$CATALINA_OUT"
6 if [ "$1" = "-security" ] ; then
7 if [ $have_tty -eq 1 ]; then
8 echo "Using Security Manager"
9 fi
10 shift
11 "$_RUNJAVA" "$LOGGING_CONFIG" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
12 -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
13 -Djava.security.manager \
14 -Djava.security.policy=="$CATALINA_BASE"/conf/catalina.policy \
15 -Dcatalina.base="$CATALINA_BASE" \
16 -Dcatalina.home="$CATALINA_HOME" \
17 -Djava.io.tmpdir="$CATALINA_TMPDIR" \
18 org.apache.catalina.startup.Bootstrap "$@" start 2>&1 | /usr/sbin/cronolog "$CATALINA_BASE"/logs/catalina.out.%Y-%m-%d.out >> /dev/null &
19
20 else
21 "$_RUNJAVA" "$LOGGING_CONFIG" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \

27
28 fi
3 查看原来的catalina
1 [ghl@app_51 bin]$ sed -n "453,491P" catalina.sh.bak
2 shift
3 if [ -z "$CATALINA_OUT_CMD" ] ; then
4 touch "$CATALINA_OUT"

6 else

8 fi
9 if [ ! -z "$CATALINA_PID" ]; then
10 catalina_pid_file="$CATALINA_PID"
11 else
12 catalina_pid_file=/dev/null
13 fi
14 if [ "$1" = "-security" ] ; then

每一个前十年都想不到后十年我会演变成何等模样，可知人生无常，没有什么规律，没有什么必然。
只要我还对新鲜的知识、品格的改进、情感的扩张、有胃口，这日子就是值得度过的。
