本文深入探讨了Apache Tomcat服务器在使用shutdown.sh脚本关闭时遇到的常见错误，包括连接拒绝异常和PID文件未移除的问题。通过分析catalina.sh脚本和Java虚拟机行为，提供了多种解决方案，如修改项目实现方式、使用强制停止选项和调整停止时机。

背景：执行/shutdown.sh偶尔会报错如下，但是大部分时间还是比较正常的，希望能解决掉它

1，报错信息如下：

[root@ptbin]# ./shutdown.sh

Tomcat did not stop in time. PID file was not removed.

2，去看下pid是否存在：

[root@pt~]# ll /var/tomcat/
total 12
-rw-r–r--. 1 root root 5 Jun 12 15:41 9300.pid
[root@pt~]#

tomcat的pid确实存在，与这个pid无关

3，解决办法：

解决办法有多种

3.1 解决办法1：修改java项目的实现方式

可能项目中用到了ScheduledThreadPoolExecutor（可能是未接受stop消息导致的），导致了shutdown命令未能成功。将ScheduledThreadPoolExecutor改成spring的quartz调度就ok了。

3.2 解决办法2，加上-force强行stop掉

在catalina.sh里面
exec “ $P R G D I R " / "$ EXECUTABLE” stop -force “$@”
大家查看shutdown.sh的代码：

[root@ptbin]# vim shutdown.sh 

PRG="$0"

while [ -h "$PRG" ] ; do
  ls=`ls -ld "$PRG"`
  link=`expr "$ls" : '.*-> \(.*\)$'`
  if expr "$link" : '/.*' > /dev/null; then
    PRG="$link"
  else
    PRG=`dirname "$PRG"`/"$link"
  fi
done

PRGDIR=`dirname "$PRG"`
EXECUTABLE=catalina.sh

# Check that target executable exists
if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then
  echo "Cannot find $PRGDIR/$EXECUTABLE"
  echo "The file is absent or does not have execute permission"
  echo "This file is needed to run this program"
  exit 1
fi

exec "$PRGDIR"/"$EXECUTABLE" stop "$@"

发现并没有echo "Tomcat did not stop in time. PID file was not removed.“的提示信息，那么报错信息肯定不是在shutdown.sh脚本里面，大家看到shutdown.sh最后有引用其它脚本exec "$PRGDIR"/"$EXECUTABLE" stop "$@"来关闭tomcat，再看到”$EXECUTABLE变量所指向的是catalina.sh，所以问题核心是在catalina.sh里面。

打开catalina.sh发现只有第453行里面有这样提示信息，如下：

433   if [ ! -z "$CATALINA_PID" ]; then
434     if [ -f "$CATALINA_PID" ]; then
435       while [ $SLEEP -ge 0 ]; do
436         kill -0 `cat "$CATALINA_PID"` >/dev/null 2>&1
437         if [ $? -gt 0 ]; then
438           rm -f "$CATALINA_PID" >/dev/null 2>&1
439           if [ $? != 0 ]; then
440             if [ -w "$CATALINA_PID" ]; then
441               cat /dev/null > "$CATALINA_PID"
442             else
443               echo "Tomcat stopped but the PID file could not be removed or cleared."
444             fi
445           fi
446           break
447         fi
448         if [ $SLEEP -gt 0 ]; then
449           sleep 1
450         fi
451         if [ $SLEEP -eq 0 ]; then
452           if [ $FORCE -eq 0 ]; then
453             echo "Tomcat did not stop in time. PID file was not removed."
454           fi
455         fi
456         SLEEP=`expr $SLEEP - 1 `
457       done
458     fi

看到关键代码判断 if [ $FORCE -eq 0 ]; 那么这里就是表明前面执行异常，但是不是force强行停止掉，所以要抛一个exception出来，告诉你没有stop成功。

那么，我们可以在这里设置一个force命令来让tomcat强行stop掉。

[root@ptbin]# vim shutdown.sh
exec "$PRGDIR"/"$EXECUTABLE" stop "$@"  
#改成如下
exec "$PRGDIR"/"$EXECUTABLE" stop -force "$@"
#然后再执行shutdown.sh操作，ok，就不会报错，正常执行完毕了。

查看执行结果如下：

[root@ptbin]# ./shutdown.sh 
Using CATALINA_BASE:   /usr/local/app/apache-tomcat-6.0.37_9300
Using CATALINA_HOME:   /usr/local/app/apache-tomcat-6.0.37_9300
Using CATALINA_TMPDIR: /usr/local/app/apache-tomcat-6.0.37_9300/temp
Using JRE_HOME:        /usr/lib/jvm/java

Using CATALINA_PID:    /var/tomcat/9300.pid
[root@ptbin]#

通过设置echo提示信息，找到报错执行语句，大家看到报错的真正原因是在于执行这一句：

/usr/lib/jvm/java/bin/java -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Xms512m -Xmx1024m -Xss1024K -XX:PermSize=256m -XX:MaxPermSize=512m -XX:+PrintGCDetails -Xloggc:/logs/gc/9300.gc -Djava.endorsed.dirs=/usr/local/app/apache-tomcat-6.0.37_9300/endorsed -classpath /usr/local/app/apache-tomcat-6.0.37_9300/bin/bootstrap.jar -Dcatalina.base=/usr/local/app/apache-tomcat-6.0.37_9300 -Dcatalina.home=/usr/local/app/apache-tomcat-6.0.37_9300 -Djava.io.tmpdir=/usr/local/app/apache-tomcat-6.0.37_9300/temp org.apache.catalina.startup.Bootstrap stop后报错。

对于catalina.sh里面的就是这一句：

 echo "0000002" 
  "$_RUNJAVA" $LOGGING_MANAGER $JAVA_OPTS \
    -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
    -Dcatalina.base="$CATALINA_BASE" \

	echo "0000003"

对比下3.3.1代码报错的代码以及bash执行结果命令，

	"$_RUNJAVA" $LOGGING_MANAGER $JAVA_OPTS \
    -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
    -Dcatalina.base="$CATALINA_BASE" \
    -Dcatalina.home="$CATALINA_HOME" \
    -Djava.io.tmpdir="$CATALINA_TMPDIR" \
    org.apache.catalina.startup.Bootstrap "$@" stop

的执行结果都是一样的，没有差别，所以就是说问题在于执行catalina.sh stop的时机问题，那么这个时机不对，就会造成stop失败。在经过几次测试后，发现在以下几种情况会造成tomcat类似的错误：

（1）是由于tomcat还没有启动完成的时候，你去执行shutdown.sh会报错，这个时候不允许stop，会报错。
（2）当tomcat上的web工程正在执行一项任务的时候，tomcat会等待不允许你stop也会保错的。
（3）其它未知原因。

4，解决办法

4.1 加上-force参数，再启动后关闭，就不会报错

[root@ptbin]# ./shutdown.sh 
Using CATALINA_BASE:   /usr/local/app/apache-tomcat-6.0.37_9300
Using CATALINA_HOME:   /usr/local/app/apache-tomcat-6.0.37_9300
Using CATALINA_TMPDIR: /usr/local/app/apache-tomcat-6.0.37_9300/temp
Using JRE_HOME:        /usr/lib/jvm/java
Using CLASSPATH:       /usr/local/app/apache-tomcat-6.0.37_9300/bin/bootstrap.jar
Using CATALINA_PID:    /var/tomcat/9300.pid
[root@ptbin]#

4.2 等待一会再shutdown.sh等tomcat里面web工程执行完的时候，没有新请求了，shutdown就ok了。

[root@ptbin]# ./shutdown.sh 
Using CATALINA_BASE:   /usr/local/app/apache-tomcat-6.0.37_9300
Using CATALINA_HOME:   /usr/local/app/apache-tomcat-6.0.37_9300
