How CentOS can see which application/process is consuming the port

Sometimes when you start an app, you'll see that the port is already occupied, or that you're feeling that some ports are not being used but found to be open. At this point we want to know which application/process is using the port.

CentOS can be viewed with netstat or lsof, under Windows can also be viewed with netstat, but the parameters will be different

Linux:

Netstat-nap #会列出所有正在使用的端口及关联的进程/Application
Lsof-i:p ortnumber #portnumber要用具体的端口号代替, you can list this port directly listen to the process/application

One, check which process the port is taking up

The code is as follows	Copy Code
Netstat-lnp|grep #88请换为你的apache需要的端口, such as: 80

SSH executes the above command to see which process is being used by Port 88. For example, the process number is 1777.

Second, view the details of the process

PS 1777

SSH executes the above command. View the program detail path for the corresponding process number. Such as.

Third, kill the process, restart Apache

The code is as follows	Copy Code
Kill-9 1777 #杀掉编号为1777的进程 (Please enter according to the actual situation) Service httpd Start #启动apache

SSH executes the above command, and if there is no problem, Apache will be able to start normally.
