What is Imagick?
Imagick is a PHP extension that provides a wrapper for the ImageMagick library, allowing PHP developers to access and manipulate images using ImageMagick’s functionality. It enables PHP scripts to perform a wide range of image processing tasks, such as resizing, cropping, rotating, applying filters and effects, and converting between different image formats.
With Imagick, PHP developers can harness the power of ImageMagick directly within their PHP applications, making it easier to work with images and perform complex image manipulations programmatically. This extension is commonly used in web development for tasks such as generating thumbnails, processing user-uploaded images, creating dynamic image content, and more.
Imagick provides an object-oriented interface in PHP, making it intuitive to use for developers familiar with object-oriented programming principles. Additionally, it offers extensive documentation and examples to help developers get started with integrating image processing capabilities into their PHP applications efficiently.

Any price and availability information displayed on [relevant Amazon Site(s), as applicable] at the time of purchase will apply to the purchase of this product.)Update Rocky Linux Server:
Start by logging into your Linux server as the root user. To do this, you can use any SSH client of your choice, such as PuTTY or the built-in terminal in Linux or macOS. Once you have successfully logged in, you will have administrative access to your server.
Next, execute the following command in the Linux terminal to update your Rocky Linux server. This will ensure that all installed packages are up-to-date with the latest security patches and software improvements, optimizing the system’s performance and stability.
# dnf update -y
If above command updates your Linux Kernel, then you should reboot your Linux server, before moving forward with this Linux tutorial.
# reboot
Note down the versions of Linux operating system and Linux Kernel.
# cat /etc/rocky-release Rocky Linux release 9.1 (Blue Onyx) # uname -r 5.14.0-162.23.1.el9_1.x86_64
Install ImageMagick Prerequisites:
Here, we are installing ImageMagick with PHP-Imagick to use by a web application for conversion of images.
Now, there is a question arises in the mind of many readers that:
Is it mandatory to setup a LAMP server for ImageMagick?
The answer is certainly NOT.
You can easily install ImageMagick separately on a Linux server. But it is being observed that, the ImageMagick is most commonly used by web applications. Therefore, we are installing a PHP based web server here.
Execute following dnf command to install Apache and PHP on Rocky Linux 9.
# dnf install -y httpd php-fpm
Enable and start Apache and PHP services.
# systemctl enable --now httpd php-fpm Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service. Created symlink /etc/systemd/system/multi-user.target.wants/php-fpm.service → /usr/lib/systemd/system/php-fpm.service.
To ensure that your websites are accessible over the network, it is crucial to allow the HTTP service through the Linux firewall. By doing this, you enable incoming traffic on port 80, which is required for serving web pages to users. If the firewall is blocking HTTP traffic, your websites will not be reachable from external networks. Follow the necessary steps to configure the firewall settings, ensuring that HTTP service is properly enabled and your websites can be accessed without any restrictions.
# firewall-cmd --permanent --add-service=http success # firewall-cmd --reload success

ImageMagick is available through the EPEL (Extra Packages for Enterprise Linux) repository, which provides additional software packages not included in the default Linux repositories. To access and install ImageMagick, you first need to enable the EPEL repository on your system. This repository contains a wide range of useful tools and utilities, including ImageMagick, that are essential for various tasks on Linux servers. To enable the EPEL repository, simply execute the following dnf command. Once enabled, you’ll be able to install ImageMagick and other packages directly from EPEL with ease.
# dnf install -y epel-release
Additionally, you may enable the CRB (CodeReady Builder) yum repository.
Be informed that, Power Tools repository has been replaced by CRB repository in Rocky Linux 9.
Enable the CRB repository executing following Linux command.
# /usr/bin/crb enable Enabling CRB repo CRB repo is enabled and named: crb
Build yum cache for newly installed yum repositories.
# dnf makecache
Install ImageMagick Software on Linux
Now that all the necessary repositories have been successfully set up, you are ready to install ImageMagick on your Linux system. With the EPEL repository enabled, the process becomes straightforward. You can easily install ImageMagick and all its dependencies by invoking a simple dnf command in your terminal. This will ensure that the latest version of ImageMagick is downloaded and installed, allowing you to leverage its powerful image manipulation capabilities on your server. Follow the command below to complete the installation and get ImageMagick up and running.
