Install PHP 7.4 and 8.1 in AlmaLinux 9

#  dnf update

Installing the EPEL and Remi Repository

To install PHP 8.1, we need to add and enable the Remi RPM repositories. Before that, we also need to install the EPEL repository. Let’s start by installing the EPEL repository with the following command:

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

Next, we can install the Remi repository by running the following command:

dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm

This will add the Remi repository to your system, which contains the PHP 8.1 packages that we need.

Listing Available PHP Versions

Once the Remi repository is installed, you can list the available PHP module streams by running the following command:

dnf module list php

This command will display the available PHP versions, including PHP 7.4, PHP 8.0, and PHP 8.1.

Installing PHP 7.4

To install PHP 7.4, we can use the remi repository. Run the following command to install PHP 7.4:

dnf module install php:remi-7.4

Verifying the Installed PHP Version

#  php -v

The command will display the PHP version installed on your system. In this case, it should show PHP 7.4.

# dnf install  php-mysql php-xml pcre php-common php-mbstring php-pear php-json curl unzip -y    

# dnf install php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-json php-mcrypt php-mssql php-snmp php-soap php-tidy curl curl-devel  -y

Installing PHP 8.1

Now, let’s proceed with installing PHP 8.1. Run the following command to install PHP 8.1:

dnf module install php:remi-8.1

This command will install the PHP 8.1 packages and dependencies from the Remi repository.

Verifying the Installed PHP Version

After the installation is complete, you can verify the installed PHP version by running the following command:

php -v

The command will display the PHP version installed on your system. This time, it should show PHP 8.1.

Updating the System and Installing Packages

To keep your system up-to-date and install any necessary packages, you can run the following command:

dnf update
