Solution to apache httpd.exe occupying high CPU and memory and sending large traffic packets to the external network_PHP tutorial

This is a problem I encountered myself. On a machine, apache httpd.exe occupied high CPU and memory and sent large traffic packets to the external network. After the efforts of the service provider and myself, it was finally solved. Thank you. tuidc.com.

This happens to my machine a lot. Let’s take a look at my step-by-step solution.

First, close all udp products on the server

Second, that is to detect whether the server is poisoned by the website. After analysis, it is that the dedecms used by one of my corporate websites has been infected by phpddos. This way, it will be easier to solve if the cause is found,

Third, delete the phpddos file and ensure website security.

Experience:

Later I downloaded the phpddos code and took a look. Its core code uses fsockopen(). If your server does not use this php function, you can directly disable it, so phpddos has no choice.
