Sometimes you need to look under Linux to see which port a process occupies, but only know the general name of the process, such as to see on which port hadoop's namenode is running in order to connect in eclipse.

First use the ps command to view the id of the process:

The code is as follows:

$ps-ef | grep Name

The second field for each line (which takes up several lines for a long time) is the process's id.

Of course, processes running in the java virtual machine, such as hadoop daemons, can be viewed directly with the jsp command:

The code is as follows:

$jps | grep Name

Or if you already know the exact name of the process, you can check it with pidof:

The code is as follows:

$pidof Name

After you see the process id, use the netstat command to see the port it occupies:

The code is as follows:

$netstat-nap | grep pid
