Install imagemagick with PHP imagick extension on CentOS

To install imagemagick with PHP imagick extension on Linux CentOS you must follow these steps:

yum install ImageMagick
yum install ImageMagick-devel
pecl install imagick

If you have an error like this:

root@myhost [~]# pecl install imagick
downloading imagick-3.0.1.tgz ...
Starting to download imagick-3.0.1.tgz (93,920 bytes)
.....................done: 93,920 bytes

Please provide the prefix of Imagemagick installation [autodetect] :

See `config.log' for more details.
ERROR: `/root/tmp/pear/imagick/configure --with-imagick' failed

Look at your /tmp folder… pretty surely it is mounted with noexec flag. Remount it without noexec and retry:

mount -o remount,rw /tmp

At the end of the installation, create an inclusion file for imagick.so module and restart apache:

echo "extension=imagick.so" > /etc/php.d/imagick.ini
/etc/init.d/httpd restart

Test the correct load of the imagick module with:

php -m | grep imagick
