goto命令提示符
netstat -aon
對于Linux
netstat -tulpn | grep 'your_port_number'
它會向您顯示類似

檢查哪個進程綁定了您的端口。在上面的示例中，248如果您確定需要殺死該進程火，則為現(xiàn)在
Linux：
kill -9 248
視窗：
taskkill /f /pid 248
它會殺死那個過程

如果在Linux上，您可以使用此腳本殺死現(xiàn)有的Tomcat。
#/bin/bash
if [ `whoami` != root ]; then
echo "Please run this script as root or using sudo"
exit
fi
echo
echo "finding proceses that have name java and established connections status"
echo
echo "Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name"
netstat --tcp --programs | grep "ESTABLISHED" | grep "java"
echo
echo "finding proceses that use port 8080 or http-alt"
echo
netstat --tcp --programs | grep ':8080\|:http-alt'
echo -n "Do you wish to kill a process listed above?[Y/n]"
read choose
if [ "$choose" = "Y" ] || [ "$choose" = "y" ] || [ -z "$choose" ]
then
echo "enter pid to kill"
read procesId
kill -9 $procesId
fi
echo "done exiting"
exit 0
