The other day, I had to install ImageMagick on Linux, it was quite difficult because it was my first time to install it.
First of all, there was not much information available. Even if I find information, either the OS was different or the version was old, or the method was completely different.
Every time I get an error about package dependencies, I get garbled texts.
This is a reminder of when it worked in the AlmaLinux 8 environment. May it be useful to someone in future.
Difference between ImageMagick and Imagick
The first thing to understand is that ImageMagick and Imagick are different. (If you know what I'm talking about, skip this section.)
ImageMagick is a free and open-source software for editing and converting image files.
Imagick is a PHP extension that allows you to create and edit image files from PHP using the ImageMagick API.
So please note that if you just install ImageMagick, you cannot run it from the PHP side!
The environment
AlmaLinux 8.8
Apache 2.4.37
PHP 8.1.23
PHP-FPM 8.1.23
Install remi repository to begin.
Install ImageMagick
If you try to install it without thinking, you will get an error like this because the required package does not exist just like the following,
dnf install --enablerepo=remi ImageMagick7 ImageMagick7-devel

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)add and activate the repository that is called "PowerTools",
dnf config-manager --set-enabled powertoolsand then when I tried again, I was able to install it successfully, including dependencies!
dnf install --enablerepo=remi ImageMagick7 ImageMagick7-devel
