In Linux if stopTomcat.shis not stopping tomcat then
在 Linux 中，如果stopTomcat.sh不停止 tomcat 那么
ps -ef | grep "tomcat"
kill -9 <PID>
kill the running instance of tomcat, killing your java application wont kill tomcat
杀死tomcat的运行实例，杀死你的java应用程序不会杀死tomcat
To get the running tomcat port use sudo netstat -lnp | grep <PID>
要获取正在运行的 tomcat 端口，请使用 sudo netstat -lnp | grep <PID>

Try changing the port number from 8005 to some other port number and restart Eclipse .
尝试将端口号从 8005 更改为其他端口号并重新启动 Eclipse。
sometimes it may happen that the port number is blocked by sudden termination of process
有时可能会发生端口号因进程突然终止而被阻塞的情况
