Installing Redis and phpredis

[tininho]

How do I install Redis and phpredis to work with Litespeed correctly?

After following the guide (see link below), I get the following error when I try to open my Magento site:

Fatal error: Class 'Credis_Client' not found in /var/www/#####/app/code/community/Cm/RedisSession/Model/Session.php on line 57

Should I edit the Litespeed's php.ini to include extension=redis.so, right?

But when I edit the php.ini under /php folder and restart the server, phpinfo.php is not changing. Which php.ini I need to change?
