Copy after loginCopy after login- Create the example folder in the /var/www/html directory and place the website source code file in this folder.
Summary:
Through the above four steps, we successfully built a web server on CentOS. Readers can further configure and adjust according to their own needs, such as adding SSL certificates, setting firewall rules, etc. I hope this article can help beginners who are building web servers, so that everyone can get started quickly and enjoy the fun of web development.
Code example:
<!DOCTYPE html> <html> <body> <?php echo "Hello World!"; ?> </body> </html>
The above is a simple PHP sample code that outputs Hello World to the browser. Readers can access this code file by setting a virtual host in the Apache configuration file.
