Notes on using Yum to install PHP in Linux systems

Installing PHP in Linux systems is an important task in website development. Yum is a convenient package management tool that can easily install and manage software packages. This article will introduce the precautions for using Yum to install PHP in Linux systems and provide specific code examples.

First, make sure your Linux system has the Yum package management tool installed. If it is not installed, you can install it through the following command:

sudo yum install yum

Next, we need to configure the Yum source to ensure that the latest PHP software package can be downloaded. Usually, we will use EPEL repository and Remi repository to get PHP packages. Here are the steps to configure both repositories:

1. Configure the EPEL repository:

sudo yum install -y epel-release

2. Configure Remi repository:

sudo yum install -y https://rpms.remirepo.net/enterprise/remi-release-7.rpm

sudo yum-config-manager --enable remi-php74

sudo yum install -y php php-cli php-common php-mysqlnd php-gd php-xml php-mbstring

During the installation process, Yum automatically resolves package dependencies and downloads the necessary files. After the installation is complete, we can check the version of PHP through the following command:

php -v

At this time, you can use PHP to write website code and run it on the server side. If you need to install other PHP extensions or components, you can install the corresponding software packages through Yum.

In addition to installing PHP, you also need to pay attention to the following:

1. Update the Yum source: Update the Yum source regularly to get the latest packages and security updates.

3. Firewall settings: Make sure the firewall has allowed traffic to PHP related ports to ensure that the PHP website can be accessed normally.

To sum up, using Yum to install PHP in a Linux system is a relatively simple operation, but you need to pay attention to configuring the Yum source, installing PHP software packages and related dependencies, and subsequent configuration. and management work.
