ServerPilot cannot provide support for customizations. We always recommend avoiding customizations unless you absolutely need to customize your server. Customizations increase complexity, and complexity often leads to downtime and vulnerabilities.
The ImageMagick extension supports PHP 5.6, 7.0, 7.1, 7.2, 7.3, 7.4, 8.0, 8.1, 8.2, and 8.3.
The ImageMagick extension, called Imagick when referring to the PHP extension, is a native PHP extension to create and modify images using the ImageMagick API.
To install this extension, run the following commands as your server's root user:
sudo apt-get -y install gcc make autoconf libc-dev pkg-config sudo apt-get -y install libmagickwand-dev sudo peclX.Y-sp install imagick
When prompted with:
Please provide the prefix of Imagemagick installation [autodetect] :
just press Enter; do not type a prefix (that is, allow autodetect).
Once installed, create a configuration file for the extension and restart PHP by running the following commands as root:
sudo bash -c "echo extension=imagick.so > /etc/phpX.Y-sp/conf.d/imagick.ini" sudo service phpX.Y-fpm-sp restart
In order to allow ImageMagick to process PDF files, you must SSH into your server as root and edit the following file:
/etc/ImageMagick-6/policy.xml
Locate the line:
<policy domain="coder" rights="none" pattern="PDF" />
Comment out this line by replacing it with the following:
<!--<policy domain="coder" rights="none" pattern="PDF" />-->
Finally, restart PHP:
sudo service phpX.Y-fpm-sp restart
You can verify the ImageMagick extension is installed with this command:
phpX.Y-sp -i | grep imagick
If ImageMagick is installed correctly, you will see the following:
/etc/phpX.Y-sp/conf.d/imagick.ini, imagick imagick module => enabled imagick module version => 3.4.3RC1 imagick classes => Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator Imagick compiled with ImageMagick version => ImageMagick 6.6.9-7 2016-06-01 Q16 http://www.imagemagick.org Imagick using ImageMagick library version => ImageMagick 6.6.9-7 2016-06-01 Q16 http://www.imagemagick.org imagick.locale_fix => 0 => 0 imagick.progress_monitor => 0 => 0 imagick.skip_version_check => 0 => 0
To uninstall this extension, as root run the commands:
sudo rm /etc/phpX.Y-sp/conf.d/imagick.ini sudo peclX.Y-sp uninstall imagick
Next, restart PHP-FPM with the command:
sudo service phpX.Y-fpm-sp restart
