[Image processing software] ImageMagick and Imagick installation memo

Hello.
This is Kawa from the OOM Killer System Solutions Department, reporting once a day.

I recently had to install ImageMagick on a Linux machine, and
since it was my first time, it was quite a struggle. First of all, there wasn't much information available.
Even when there was, it was for a different OS, an older version, or a completely different method.
Every time I encountered an error due to package dependencies, I had to deal with it.

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

Difference between ImageMagick and Imagick

First, it's important to understand that they are two different things. (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 using the ImageMagick API from PHP.

Therefore,that simply installing ImageMagickwon't allow you to run it from the PHP side!(It's complicated.)

About the environment

AlmaLinux 8.8
Apache 2.4.37
PHP 8.1.23
PHP-FPM 8.1.23

As a preliminary step, install the remi repository

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

Installing ImageMagick

If you try to install it without thinking, the necessary 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 the repository "PowerTools",

dnf config-manager --set-enabled powertools

When I tried again, the installation was successful, including all dependencies!

Installing Imagick

If you leave this as it is, a dependency error will occur, so you will need to 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 using pecl.
"Please provide the prefix of ImageMagick installationPress Enter when prompted

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] :

The message displayed upon completion of the installation instructs you to "You should add "extension=imagick.so" to php.ini," so add the following to the bottom of your php.ini file.

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

Restart Apache and PHP-FPM

systemctl restart httpd systemctl restart php-fpm.service

After restarting, install the additional PHP package and if it appears in the PHP module, it's OK

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