Well I am totally baffled by this one and have never had this problem before. I dont know if it is litespeed or what. But anyway, I got this client's server, it used to be on a cluster, now its just litespeed. I installed php and everything just like I normally would any other server but I now have the strangest problem. I noticed that the user was not creating session files in /tmp nor would create any cache files in eaccelerator's cache directory. AT first I got an shmget error doing php -v but adjusting some things in sysctl.conf remedied that. I have recompiled php over and over with different configure options and still end up at same place. When you do php -v as root you get PHP 5.2.9 (cli) (built: Jun 14 2009 11:23:06) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies with eAccelerator v0.9.5.3, Copyright (c) 2004-2006 eAccelerator, by eAccelerator with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies with Zend Optimizer v3.3.3, Copyright (c) 1998-2007, by Zend Technologies Plus it will create session and cache files for root When you su to the user and do php -v you get PHP 5.2.9 (cli) (built: Jun 14 2009 11:23:06) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies Creates no cache or session files. As far as the system it is a centos 5 i386, using default kernel, selinux is disabled and all that. ALl file permissions are correct. No open base dir is set.
