Solve the problem of port 80 being occupied (close the occupied port, general purpose)

Table of contents

1. Win+R enter cmd to run the command prompt as an administrator

2. Enter: netstat -ano to view all process information, and find the PID corresponding to port 80 (corresponding to the local address, for example: 0.0.0.0:80)

3. Open the task manager and find the application process corresponding to the PID (the Tomcat server is enabled at this time)

4. System process occupation

4. System process occupation

If the system process occupies port 80, we can’t close it directly, then enter netsh http show servicestate in the command prompt

Figure 4

Then enter the tskill PID (for example: tskill 15320 to close the process

Note: The complete command is: taskkill /pid 15320 /f)
or go to the task management, as shown in Figure 3, close it, and release port 80.
