Explore how to install PHP on CentOS

PHP is a popular scripting language used for dynamic web development. CentOS is a popular Linux operating system that is widely used for web servers. Installing PHP on CentOS is a very important task as it helps people create powerful web applications. In this article, we will explore how to install PHP on CentOS.

First, we need to prepare a CentOS server. Make sure you have CentOS installed and you have root permissions. If you do not have root privileges, you will not be able to perform the operations in this article. If you don't know how to install CentOS, please refer to the official CentOS documentation.

Next, we need to access the server’s terminal in order to install PHP via the command line. There are several ways to access the terminal, the most common is using the ssh protocol. Using the ssh protocol requires an ssh client to be installed on the local computer. If you are using macOS or Linux operating system, you can open the Terminal application and enter the following command:

ssh root@your_server_ip_address

Please replace "your_server_ip_address" with the IP address of your CentOS server. If you are using a Windows operating system, you can use an ssh client such as Putty.

Now, we have successfully connected to the terminal of the CentOS server. Next, we need to install PHP. CentOS uses the yum command by default to install software packages. Therefore, we will use yum to install PHP. Enter the following command in the terminal:

yum install php

This will install PHP and all its dependencies. During the installation process, you will be prompted to accept the GPG key for the package. Press the "y" key to accept the key.

After the installation is complete, you need to restart the Apache web server for PHP to take effect. Enter the following command in the terminal:

systemctl restart httpd

The above command will restart the Apache web server. Now you can write a simple PHP script and test whether it works properly. Enter the following command in the terminal:

echo "<?php  phpinfo(); ?>" > /var/www/html/info.php

Now, you can visit "http://your_server_ip_address/info.php" in your browser to view the details of PHP. Note that you need to replace "your_server_ip_address" with the IP address of your CentOS server.

In this article, we have demonstrated how to install PHP on CentOS. The installation process is very simple and only requires a few commands to complete. Now you can start using PHP to create powerful web applications.
