Install ISPConfig

5.01 Overview

  ISPConfig is a control panel that allows users to easily administer their hosting accounts on Linux servers.

5.02 Download Latest Version Of ISPConfig

  Change to the ‘/tmp’ directory and then download the latest version of ISPConfig using these commands:

cd /tmp

wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz

  Now we need to unzip the downloaded file:

tar xfz ISPConfig-3-stable.tar.gz

5.03 Install ISPConfig

  Now we will change into the installation directory of the unzipped file:

cd ispconfig3_install/install/

  The next step is to run the ISPConfig installer:

php -q install.php

  Once the ISPConfig installer starts you will need to follow these steps to get ISPConfig installed.

root@server:/tmp# tar xfz ISPConfig-3-stable.tar.gz
root@server:/tmp# cd ispconfig3_install/install/
root@server:/tmp/ispconfig3_install/install# php -q install.php

5.04 Open ISPConfig Port

  Once the installation completes open the ISP Config login port in the firewall:

firewall-cmd --permanent --add-port=8080/tcp

firewall-cmd --reload

  OPTIONAL: You can reboot the computer if you want.

reboot

5.05 Confirm ISPConfig Login

  Open a browser on your computer or a device connected to same network, log into ISPConfig (https://192.168.0.150:8080 or https://localhost:8080)

  Enter ‘admin’ for the username and enter your password to confirm you can log in. You should see your dashboard home page.

5.06 Install Multiple Versions Of PHP

  Now to install PHP 5.6 and 7.0 – 8.1 as PHP-FPM & FastCGI for ISPConfig 3 with apt on Debian 11.

  The PHP version can later be selected in the ISPConfig 3 website settings for each site individually. This feature works with PHP-FPM and FastCGI. We will install PHP 5.6, 7.x and 8.x as a PHP-FPM and a FastCGI version on a Debian server by using the PHP packages from sury.org.

  We will install PHP directly from Debian PHP Package maintainers site https://packages.sury.org/php/ with apt-get. This will not overwrite the existing installation but will change the default used PHP version to the newest installed one! So it is very important to add a new PHP version for the installed version to ISPConfig and change all sites to this version first. If you are using cron jobs calling PHP scripts you have to adapt them too, later more on that.

  Because other packages as openssl are updated too, the installed packages from sury.org can not simply removed after installation. You first have to downgrade this packages to the Debian versions before you are able to remove the PHP packages without breaking other packages. The simplest way for me was to deactivate the new added repository, then installed packages from sury.org will apear as self created or deprecated packages in aptitude and you are able to downgrade package after package.

  Please note that PHP-FPM can be used on both Apache and Nginx servers while FastCGI is available for Apache servers only.

5.07 Configure ISPConfig For Multiple PHP Versions

  From the ISPConfig Dashboard Home Page Select System –> Additional PHP Versions –> Add new PHP version. You should see this screen:

  Enter the name of the custom PHP version:

  Click on the FastCGI Settings tab and fill out the fields as follows:

Path to the PHP FastCGI binary: Use settings from list below
Path to the php.ini directory: Use settings from list below

  Then click on the PHP-FPM Settings tab and fill out the fields as follows:

Path to the PHP-FPM init script: Use settings from list below
Path to the php.ini directory: Use settings from list below
Path to the PHP-FPM pool directory: Use settings from list below

  Important step for cron jobs

  If you use cron jobs calling PHP scripts you also have to tell cron which version to use. Add php7 in the beginning of the command to use the Debian’s version. If you are not sure what you exactly are using follow the symlink /usr/bin/php and use its final destination as prefix.

  Add other PHP versions:

  Currently there are 3 versions available at https://packages.sury.org/php/ and you have to repeat the last step now for every version you will install. I used the PHP 5.6 version settings in the example. Repeat the same steps to add PHP 7.0, PHP 7.1, PHP 7.2, PHP 7.3, PHP 7.4, PHP 8.0 and PHP 8.1. Use the following settings for each version installed:

  Set Debian default PHP back to the original version

  For Debian 11, choose 7.4 in the dialog that appears.

  The default PHP of the operating system has to remain at the original version. To fix that, run these commands:

update-alternatives --config php

5.11 Edit php.ini Configuration File

  Now we have to edit the php.ini file in each PHP version that was installed. First we edit the default version located at /etc/php/7.4/apache2/php.ini:

  We need to enable php shorthand tags and change the error reporting (so that notices aren’t shown any longer), uncomment cgi.fix_pathinfo=1, set the timezone and set the path to browscap.ini:

nano /etc/php/7.4/apache2/php.ini

[…]
; This directive determines whether or not PHP will recognize code between
; tags as PHP source which should be processed as such. It is
; generally recommended that should be used and that this feature
; should be disabled, as enabling it may result in issues when generating XML
; documents, however this remains supported for backward compatibility reasons.
; Note that this directive does not control the ; used regardless of this directive.
; Default Value: On
; Development Value: Off
; Production Value: Off
; http://php.net/short-open-tag
;short_open_tag = Off
short_open_tag = On
[…]

[…]
;error_reporting = E_ALL & ~E_DEPRECATED
error_reporting = E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT
[…]

[…]
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI. PHP’s
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
; what PATH_INFO is. For more information on PAppp.tldTH_INFO, see the cgi specs. Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec. A setting
; of zero causes PHP to behave as before. Default is 1. You should fix your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
; http://www.php.net/manual/en/ini.core.php#ini.cgi.fix-pathinfo
cgi.fix_pathinfo=1
[…]

[…]
date.timezone = 'America/New_York'
[…]

[…]
browscap]
; http://php.net/browscap
;browscap = extra/browscap.ini
browscap = /etc/php/browscap.ini
[…]

  Close and save the file.

  Now we must copy this edited version to all of the other installed versions:

cp /etc/php/7.4/apache2/php.ini /etc/php/8.1/fpm/php.ini

cp /etc/php/7.4/apache2/php.ini /etc/php/8.1/cli/php.ini

  Download the PHP version of “browscap.ini” you want to use from http://browscap.org and save it into /etc/php directory. There are 3 versions you can use, php_browscap.ini, full_php_browscap.ini and lite_browscap.ini.

cd /tmp

To use the Standard File:
wget https://browscap.org/stream?q=PHP_BrowsCapINI

cp ‘stream?q=PHP_BrowsCapINI’ /etc/php/browscap.ini

To use the Full File:
wget https://browscap.org/stream?q=Full_PHP_BrowsCapINI

cp ‘stream?q=Full_PHP_BrowsCapINI’ /etc/php/browscap.ini

To use the Lite File:
wget https://browscap.org/stream?q=Lite_PHP_BrowsCapINI

cp ‘stream?q=Lite_PHP_BrowsCapINI’ /etc/php/browscap.ini

  Now restart Apache:

systemctl restart apache2

  Finally, restart the php-fpm daemons. Run the commands for the previously installed ones:

service php5.6-fpm restart

service php7.0-fpm restart

service php7.1-fpm restart

service php7.2-fpm restart

service php7.3-fpm restart

service php7.4-fpm restart

service php8.0-fpm restart

service php8.1-fpm restart

  And that completes the setup procedures of your Web Site Hosting Server using Debian 11 and ISPConfig 3.1. Now we need to Configure ISPConfig to host the MyDomain.com website using WordPress 6.0 content management system.
