Running the Apache Server on port 81
To run
Apache Server on port 81, it is a good idea to create a
SHORTCUT on your system's
DESKTOP.
H:/ Open this folder:
H:/Apache648
H:/Apache648/ See:
H:/Apache648/Apache24Open the folder:
H:/Apache648/Apache24/bin
H:/Apache648/Apache24/bin/ Right-clickthe file:
H:/Apache648/Apache24/bin/httpd.exe
H:/Apache64/Apache24/bin/ This file:
H:/Apache64/Apache24/bin/httpd.exeChoose:
Copy
Desktop -> Paste shortcut Right-clickon the
Desktopand chose:
Paste shortcut
Desktop -> httpd.exe - Shortcut (2) The

httpd.exe - Shortcut (2)to activate the
Apache Server on port 81
Apache Server Terminal is Open The
Apache Server Terminal on port 81it is then open, ready to operate.
Apache Server Terminal is Open
The
Apache Server Terminal on port 81
must be kept open while in use.

Soon we will say how to safely close it.
Open your favorite browser To test whether the
Apache Server on port 81can 'see'
PHP scriptsopen your preferred browser.
localhost:81 Enter the URL:
localhost:81
localhost:81 This
URL will allow to display the file
H:/WEB/public_html/index.phpwhich is intended to show all of its content viewed as public.
The contents of this file will be shown, just after entering the
URL followed by
ENTER .
localhost:81/info.php Now, enter the
URL:
localhost:81/info.php
This
URL allows the display of a table with information about
PHP.
localhost:81/info.php With the display of this table, it is proven that the
Apache Server on port 81runs
PHP 8scripts perfectly.
For now, you can close your browser.

H:/Apache648/logs 
H:/Apache648/logs H:/Apache648/logs/access.log This file is created the first time the
Apache Server on port 81 is started and self-implemented each time it is shut down and then restarted.

H:/Apache648/logs H:/Apache648/logs/httpd.pid This file which is intended to store the
Apache Server on port 81 PID,
(Process ID).
This means that it is always created, at the opening of the terminal and eliminated at its closure.
It has the following format:
If you wish, you can check these files whenever you want.
To have complete control of what is displayed by each of these files, it is best to observe them with the Apache Server on port 81 out of operation.
Remember that the httpd.pid file is only active when the Apache Server on port 81 is in operation.
To update the Apache Server on port 81, you must follow the same steps used to update the Apache Server on port 80.
However, you must take care not to mix the configuration files, as these are particular to each installation.
That's it for now
