[Image processing software] Something like a memo about ImageMagick and Imagick installation

Hello.
Once a day OOM killer This is Kawa from the System Solutions Department.

The other day I had to install ImageMagick on my Linux machine, but
since it was my first time using it, I had a hard time installing it. First of all, there isn't much information available.
Even if it does, the OS is different, the version is older, or the method is completely different.
Every time you get an error with package dependencies, don't worry.

This is a memo of what went well in the AlmaLinux 8 environment. I hope it will be useful to someone in future generations.

Difference between ImageMagick and Imagick

The first thing you need to understand is that they are different. (Skip this if you already know)
ImageMagick is free open source software for editing and converting image files.
Imagick is a PHP extension module that allows you to create and edit image files from PHP using the ImageMagick API.

So, if you just install ImageMagick, you won't be able to run it from the PHP side, so be careful! (complicated)

About the environment

AlmaLinux 8.8
Apache 2.4.37
PHP 8.1.23
PHP-FPM 8.1.23

Insert the remi repository as a preliminary preparation

dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

Installing ImageMagick

If you try to install it without thinking, the required package will not exist and you will get an error like this,

dnf install --enablerepo=remi ImageMagick7 ImageMagick7-devel Last metadata expiration check: 0:54:50 ago on Fri Sep 15 15:54:10 2023. Error: Problem: cannot install the best candidate for the job - nothing provides jasper- devel(x86-64) needed by ImageMagick7-devel-1:7.1.1.15-1.el8.remi.x86_64 - nothing provides OpenEXR-devel(x86-64) needed by ImageMagick7-devel-1:7.1.1.15-1. el8.remi.x86_64 - nothing provides ghostscript-devel(x86-64) needed by ImageMagick7-devel-1:7.1.1.15-1.el8.remi.x86_64 - nothing provides jbigkit-devel(x86-64) needed by ImageMagick7- devel-1:7.1.1.15-1.el8.remi.x86_64 - nothing provides lcms2-devel(x86-64) needed by ImageMagick7-devel-1:7.1.1.15-1.el8.remi.x86_64 - nothing provides openjpeg2- devel(x86-64) needed by ImageMagick7-devel-1:7.1.1.15-1.el8.remi.x86_64 (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Add and enable a repository called "PowerTools",

dnf config-manager --set-enabled powertools

When I tried again, I was able to successfully install everything including dependencies!

Installing Imagick

If this is done as is, a dependency error will occur, so install the necessary packages in advance.

dnf install --enablerepo=remi php-pear php-devel

Verify that the pecl command is recognized

which pecl /usr/bin/pecl

Install with pecl.
Press Enter at the " Please provide the prefix of ImageMagick installation

pecl install imagick downloading imagick-3.7.0.tgz ... Starting to download imagick-3.7.0.tgz (360,138 bytes) ...................... ................................................... .done: 360,138 bytes 33 source files, building running: phpize Configuring for: PHP Api Version: 20170718 Zend Module Api No: 20170718 Zend Extension Api No: 320170718 Please provide the prefix of ImageMagick installation [autodetect] :

When the installation is complete, the message says " You should add "extension=imagick.so" to php.ini ", so add the following to the bottom of php.ini.

# Add ↓ to php.ini [PECL] extension=imagick.so

Restart Apache and PHP-FPM

systemctl restart httpd systemctl restart php-fpm.service

After restarting, install additional PHP packages, and if they appear in the PHP module, it's ok.

dnf install php81-php-pecl-imagick-im7 php -m | grep imagick imagick
