Steps To Install PHP 8.1 on Centos 7

Before you start to install PHP 8.1, you need to log in to your server as a non-root user with sudo privileges. To do this, you can follow our article the Initial Server Setup with Centos 7.

Now you can follow the steps below to complete this guide.

Installation of PHP 8 on Centos 7

First, you need to update your local package index with the command below:

Then, you need to install the Epel release on Centos 7 with the command below:

Install Remi Repository on Centos 7

PHP 8.1 is not featured in Centos’s AppStream. So you can install PHP from the (Remi) repository that deploys the latest PHP 8.1 builds. To do this, run the following command:

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

Update your local package index again:

sudo yum update -y

Now you need to remove the PHP and PHP-FPM previous versions if you have them installed on your server. To do this run the following command:

sudo yum remove php php-fpm -y

Then remove the rest of the package extensions with the command below:

sudo yum remove php* -y

Now disable the Remi repository for PHP with the following command:

sudo yum-config-manager --disable 'remi-php*'

Enable PHP Remi Repository on Centos 7

Next, you need to enable the Remi for PHP 8.1 on Centos 7 with the following command:

Run the command below to see if the Remi repository for PHP 8.1 is enabled on your server:
