以下命令
[cuser@vdev-b7-5461-4f3c-9d98-7fc3ec6 kafka]$ ps aux|grep apache

我的机器上运行了多个apache进程。有没有办法让我确定每个进程用来运行它的文件/目录？
另外，想知道他们正在使用的端口吗？
[user@vdev-37-5461-4f3c-9d98-7af28dfc3ec6 kafka]$ netstat -tulpn|grep 80
(No info could be read for "-p": geteuid()=500 but you should be root.)
tcp 0 0 :::80 :::* LISTEN -
以上命令显示正在使用端口80，但我想知道正在使用它的进程是什么？
