Installing ImageMagick / Imagick for PHP on Linux CentOS

This was tricky, so thought I'd post for peeps having problems.

1.yum install ImageMagick

2.yum install php-devel (if not installed)

NOTE: skipping step 2 leads to this problem..."ERROR: `phpize' failed".

3.yum install ImageMagick-devel

NOTE: skipping step 3 leads to this problem ... "ERROR: `/tmp/tmppccQA1/imagick-2.2.2/configure --with-imagick' failed"

4. WRONG: pecl install imagick

had problem : PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/imagick.so' - /usr/lib/php/modules/imagick.so: undefined symbol: ClonePixelWand in Unknown on line 0

fixed by uninstalling : pecl uninstall imagick

4.RIGHT : pecl install imagick-2.2.1 (don't just run pecl install imagick, version 2.2.2 doesn't work)

5. echo "extension=imagick.so" > /etc/php.d/imagick.ini (might not be neccessary)

6. vi /etc/php.ini -> add extension=imagick.so

7. /etc/init.d/httpd restart

8.php -m | grep imagick (to check if loaded.)

AND finally it should work! Hope this helps!
