Let’s start off with a freshly installed server running Ubuntu 16.04 (server).
This article assumes that you have Apache and PHP installed already.
Issue the following command at shell to install the base ImageMagick library:
sudo apt-get install imagemagick
The next step is to install the PHP library for ImageMagick, but you need to install a couple of pre-requisites for it:
sudo apt-get install gcc php-common
Now to install the imagick library:
sudo apt-get install php-imagick
Restart or reload apache:
service apache2 restart OR service apache2 reload
To verify that the imagick library has been added to php you have two options:
1) Issue the following command at shell to verify successful installation:
php -m | grep imagick
2) Drop a test.php file with the following content in the html directory (default: /var/www/html)
<?php phpinfo(); ?>
That’s it, you should be good.
