This article mainly introduces the Linux system how to remove the port occupation, the article is very detailed, has a certain reference value, interested friends must read it!

Method 1 find the process based on the port

Sudo lsof-I: get the result:

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME python3 3265 root 3U IPv4 98407 0t0 TCP *: http (LISTEN) View shows that the process occupying the port ID is 3265

Pidof python3 kills the process

Sudo kill method 2 when we know the name of the process that needs kill, we can kill according to the process name:

Sudo pkill method 3 I have measured that the process kill does not drop. Even if you execute pidof after using sudo kill, you can still see the process number. In this case, you can use kill-9.

The online explanation of the difference between kill and kill-9 is as follows:

In fact, kill sends a signal to a process id. The default signal is SIGTERM, while the signal sent by kill-9 is SIGKILL, or exit. The exit signal will not be blocked by the system, so kill-9 can kill the process smoothly. Of course, you can also use kill to send other signals to processes.
