Linux address port number is occupied

We often need to solve the problem of port occupancy under Linux, the workaround is as follows:

Linux:

1 A port number is occupied, view PID
# #根据端口查看进程信息
lsof-i:14700
# #根据进程号查看进程对应的可执行程序
PS-F-P Process number

Also available netstat
Common parameters for Netstat:-T,-u,-w, and-X represent TCP, UDP, raw, and UNIX socket connections, respectively. The-a flag, which also shows a socket waiting to be connected (that is, in listening mode). -L Displays the port being monitored (listen),-n indicates that the port number is displayed directly instead of the/etc/service to the port name, and the-p option indicates that the listener is listed with the-p parameter to display the PID

This example uses Netstat-atn to

Then you can kill the PID.
