The php running mode in cpanel uses the configuration method of fast-cgi mode

After saving, restart apache.

4. Since a large number of php processes occupy memory for a long time, you can clear the php processes once an hour. crontab -e Move the cursor to the bottom 0 * * * * ps aux | grep php | egrep -v grep | awk ‘{print $2}’ | xargs kill -9 Ctrl+O to save, Enter, Ctrl+X to exit

For step 3, some foreigners have also summarized other methods: Log in to WHM->Apache Configuration->Include Editor->Pre Virtual host Include

Special attention is paid to: - DefaultMinClassProcessCount 0 (necessary to make Idle timeout work) - ThreadStackSize (default is too high, wastes memory, the setting below is good for most and will save enough memory to allow another php thread!)
