如何回收占用8009端口的资源

sunzhaoqin

在linux下tomcat与apache协同工作一段时间后就会出现无法访问网站的情况，重新启动tomcat会提示8009端口已经被占用，无法启动tomcat

运行netstat -a -p 如下显示信息：
--------------------------------------------------------------------------------------

感觉是占用8009端口的资源没有释放，使用ps察看没有占用8009端口的进程。请问我怎样才能释放掉占用8009端口的资源呢？非常感谢

找出8009运行的进程id
lsof -i:8009

kill -9 找到的进程号
