I’ve added the gearmand distributed job system, and the PHP gearman extension to the Webtatic Yum repository.
The PHP extension is only supplied for PHP 5.3, which you can also get from the repository.
To install, first set up the Yum repostory on your system:
rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm
Then install the gearmand daemon and pecl extension:
yum install gearmand php-pecl-gearman --enablerepo=webtatic
