Also I didn't install eaccelerator at time of install and when I try to add now using: /root/sources/lsws-3.2.1/admin/misc/enable_phpa.sh after I choose eaccelerator choice 2 I get error saying: [ERROR] Cannot find PHP executable, not able to determine PHP version - also tried APC same error. I then went and reinstalled litespeed from the beginning and was able to add eaccelerator that way. Just info you may need to improve enable_phpa.sh.
