The imagick.so PHP module can’t currently be installed via PECL, due to it’s inability to write to /var/tmp. To get around that, you can install it manual:

# yum install ImageM* netpbm gd gd-* libjpeg libexif gcc coreutils make
# cd /usr/local/src
# wget http://pecl.php.net/get/imagick
# tar zxvf ./imagick-3.1.0RC1.tgz
# cd imagick-3.1.0RC1
# phpize
# ./configure
# make
# make test
# make install

This will compile imagick.so, and move it to your extensions directory specified in php.ini. Now you’ll need to add extension for imagick to php.ini:

extension=imagick.so

and restart apache with following command:

#service httpd restart
