Server Optimization Request

محروم.كوم · #1 07-27-2009, 07:10 AM

I hope I have all the required information below. Pleases advise if you need anything else. I really appreciate any help I can get as I have been having odd issues and I just want to make sure I have a good configuration moving forward on this new server.

THANK YOU in advance!

1.)
Dedicated.

2.)
Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz
4GB of DDR2 RAM
1 x 250 GB SATA II
Linux CentOS 5.3 (Final) (32bit)
2.6.18-128.2.1.el5PAE i686 Kernel

Apache 2.2.3

PHP 5.1.6 (cli) (built: Apr 7 2009 0804)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
with XCache v1.2.2, Copyright (c) 2005-2007, by mOo
with the ionCube PHP Loader v3.1.16, Copyright (c) 2002-2006, by ionCube Ltd.

MySQL 5.0.45-7.el5

Plesk 9.2.1

3.) vBulletin 3.8.3, with latest vbSEO install, also using xCache file store system in config.php

4.) I have to keep innodb enabled for Plesk to work - I suppose. When I skip-innodb mysqld can restart just fine, but plesk gives errors.

5.) Unsure on how mySQL was compiled
