Install phpsysinfo on Debain Linux

This manual method works across most distributions if the package manager method (below) is not preferred or available. Update your system packages:

sudo apt update && sudo apt upgrade

Install a web server and PHP (if not already installed). For Apache on Ubuntu:

sudo apt install apache2 php libapache2-mod-php php-xml

Ensure necessary PHP extensions like php-xml are included.
Download phpSysInfo. Get the latest version from the official GitHub repository.

wget https://github.com/phpsysinfo/phpsysinfo/archive/v3.3.2.zip

(Replace v3.3.2.zip with the latest version number if different).
Extract the archive to your web server’s root directory (e.g., /var/www/html/):

sudo unzip v3.3.2.zip -d /var/www/html/

Rename the extracted folder to something simple like phpsysinfo

sudo mv /var/www/html/phpsysinfo-3.3.2 /var/www/html/phpsysinfo

Create the configuration file. Navigate to the new directory and copy the template file:

cd /var/www/html/phpsysinfo
sudo cp phpsysinfo.ini.new phpsysinfo.ini

Adjust permissions. Ensure your web server user can read and execute files in the directory. For Apache on Ubuntu, this is typically the www-data user:

sudo chown -R www-data:www-data /var/www/html/phpsysinfo

Restart your web server to apply any PHP configuration changes

sudo systemctl restart apache2

Access phpSysInfo by navigating to http://your_server_ip/phpsysinfo in your web browser.
