The first step in setting up the environment is to install a web server such as Apache or Nginx. Here we take Apache as an example. Use the following command to install Apache in the terminal:

sudo yum update
sudo yum install httpd

After the installation is complete, start the Apache service and set it to start at boot:

sudo systemctl start httpd.service

sudo vim /var/www/html/info.php

Enter the following content in the info.php file:

<?php phpinfo(); ?>

After saving and exiting the file, enter the public IP address of the cloud server in the browser, Add /info.php, that is:

http://你的IP地址/info.php

to see PHP related information, such as PHP version, configuration file path, etc., indicating that the PHP environment has been successfully established.

5. Install php extensions

In php applications, you need to install some php extensions to run properly. Here are some common extension installation methods.
