Linux views the ports it occupies based on the process name (or PID) __linux

Sometimes you need to view a process in Linux that uses that port, but only the approximate name of the process, such as to see which port the Namenode of Hadoop runs on, to connect in eclipse. One method is as follows, may compare rubs, please the advice of Daniel.

First view the ID of the process with the PS command: $ ps-ef | The second field in the grep Name where each row (which takes up a number of rows for a long time) is the ID of the process.

Of course, for processes running in a Java virtual machine, such as the daemon for Hadoop, you can view it directly with the JSP command: $ JPS | grep name or already knows the exact name of the process, you can use Pidof to view: $ pidof name after you see the process ID, use the netstat command to view the ports it occupies: $ netstat-nap | grep pid http://www.cnblogs.com/liuzhengliang/p/4609632.html
