How to use yum to install and build a PHP environment in Linux

In Linux systems, PHP is one of the important components for building web applications. In order to set up a PHP environment on a Linux system, some configuration and installation are required. This article will introduce how to use yum to install the PHP environment and build PHP applications.

1. First, make sure the yum package manager is installed on the system. If yum is not installed on your system, please execute the following command:

sudo apt-get install yum

2. Next, you need to add a yum software source to obtain the PHP package from it. Execute the following command in the terminal:

sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

3. After adding the above software sources, you can use the yum command to install PHP related software packages. Execute the following command to install PHP and its common extensions:

sudo yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml

4. After executing the above command, you need to check whether PHP is installed successfully. Please enter the following command in the terminal to check the PHP version:

php -v

If PHP is installed correctly, the terminal will output the current PHP version number.

5. Next, you need to set up the PHP configuration file. Enter the following command in the terminal to edit the PHP configuration file:

sudo vim /etc/php.ini

In the editor that opens, you can modify various PHP configuration parameters, including maximum memory limit, maximum execution time, etc.

6. After the configuration is completed, you need to restart the Apache service to make it take effect:

sudo systemctl restart httpd

Follow the above steps, and you can set up a PHP environment on the Linux system. If you want to write a web application, then you can create a PHP application file in the terminal and access the application in the browser.

In short, it is very convenient to use yum to install the PHP environment. You only need to execute a few commands to complete the installation and configuration of your PHP environment. Hope this article is helpful to you.
