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 ...

Please provide the prefix of Imagemagick installation [autodetect] :
building in /var/tmp/pear-build-root/imagick-3.0.1
running: /root/tmp/pear/imagick/configure --with-imagick
checking for egrep... grep -E
checking for a sed that does not truncate output... /bin/sed
checking for cc... cc
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.

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
