How to build a PHP web server in Linux system

PHP web page Linux building tutorial

PHP is a popular server-side scripting language used to dynamically generate web page content. Use PHP with a Linux system to build flexible, highly scalable web applications. This article will explain in detail how to set up a PHP web server in a Linux system and show some basic web development skills.

Step 1: Install Apache Web Server

Apache is a popular web server software that can efficiently handle HTTP requests on Linux systems. To install Apache in a Linux system, you can use a package manager to install it. For example, on Ubuntu/Debian, you can use the following command:

sudo apt-get update
sudo apt-get install apache2

Then, you can start the Apache service using the following command:

sudo systemctl start apache2

You can also verify that Apache is running by entering the server's IP address or domain name into your browser. If you see "Apache2 Ubuntu Default Page", it proves that Apache has been successfully installed and configured.

Step 2: Install PHP and related extensions

To use PHP with Apache, you need to install PHP and load it as an Apache module. On Ubuntu/Debian, you can install PHP and related extensions using the following commands:

sudo apt-get install php libapache2-mod-php php-mysql php-curl php-gd php-mbstring php-xml php- xmlrpc

After the installation is complete, you need to restart Apache for the PHP module to take effect:

sudo systemctl restart apache2

To verify that PHP is working properly, create a file containing the PHP code test file and save it as "test.php". Enter the following into the file:

phpinfo();
?>

Then save the file to Apache's default website directory "/var /www/html". Enter the server's IP address or domain name in your browser and add the "/test.php" path, such as "http://yourdomain.com/test.php". If you see the PHP information page, you have successfully installed PHP and integrated it with Apache.

Step 3: Create a virtual host

Virtual hosts enable Apache to host multiple domain names or websites on a single web server. To set up the virtual host, you need to edit the Apache configuration file "/etc/apache2/sites-available/000-default.conf". The following is a sample virtual host configuration:

ServerName yourdomain.com
ServerAlias www.yourdomain.com
ServerAdmin your@email.com
DocumentRoot /var/www/yourdomain.com/public_html
ErrorLog /var/www/yourdomain.com/error.log
CustomLog /var/www/yourdomain.com/access.log combined

In the above example, change "yourdomain.com ” with your own domain name, “your@email.com” with your own email address, and “/var/www/yourdomain.com/public_html” with your website root. Also replace "/var/www/yourdomain.com/error.log" with the location where the error log is stored and "/var/www/yourdomain.com/access.log" with the location where the access log is stored. To enable virtual hosting, use the following command:

sudo a2ensite yourdomain.com.conf

Finally, restart Apache:

sudo systemctl restart apache2

Now you can access your domain name and view your website content. If you haven't created a website yet, you can use an application like WordPress to build content.

Conclusion

In this article, we explained in detail how to install Apache and PHP on Linux and create a virtual host to host multiple websites. As a web developer, the powerful ability to build web applications using a combination of PHP and Linux requires certain learning and practice. I hope this article can help PHP beginners.
