Check the port occupancy under centos and kill the process

Sometimes we know that a service port is running in the background and want to close it. For example, my tomcat is port 8080, running in the background. How to turn it off?

• View the pid of this process according to the port

netstat -lnp|grep 8080 #8080 Please change to the port required by your apache

• View process details

ps 1777 #1777 is the pid obtained in the previous step

• kill process

For example: kill -9 [PID] #-9 means to force the process to stop immediately
