[mysqld]
set-variable = max_connections=500
set-variable = max_allowed_packet=512M
safe-show-database




7-) couldnt run the mysqlreport --all -tab /statistics.txt command (-bash: mysqldreport: command not found)
so i run

mysqladmin -u root -p var ext stat ver

and output

P.s: I am having problems about high load

http://www.vbulletin.com/forum/showthread.php?t=171071

69.61.21.146 server.xturkx.com server um-777.conepuppy.com um-777
127.0.0.1 localhost


dont know it is the correct version that written at centos forum

Check that localhost line in /etc/hosts is like:
127.0.0.1 localhost localhost.localdomain other.names.of.machine ...

Not like:
127.0.0.1 name.of.the.machine localhost localhost.localdomain other.names.of.machine ...

It think it is quite safe to make the line just plain:
127.0.0.1 localhost

check out CentOS + 2.6.9-34 kernel bug http://www.vbulletin.com/forum/showthread.php?t=171071 if you are having load issues you need to request your web host upgrade your linux kernel to 2.6.15.6 or higher

1. Edit /etc/my.cnf and place the following mysql server settings in /etc/my.cnf and restart mysql server afterwards


[mysqld]
safe-show-database
back_log = 75
skip-innodb
max_connections = 500

2. Install APC Cache lastest version from http://pecl.php.net/package/APC. Read install guide at http://www.vbulletin.com/forum/showthread.php?t=165367 - please remove Zend Optimizer from php.ini before installing APC Cache

3. If you just upgraded to vB 3.5.x try to disable these 4 options:

Admin CP -> vBulletin Options -> Forums Home Page Options -> Display Logged in Users?

Admin CP -> vBulletin Options -> Forum Display Options (forumdisplay) -> Show Users Browsing Forums

Admin CP -> vBulletin Options -> Thread Display Options -> Show Users Browsing Thread

Admin CP -> vBulletin Options -> Message Searching Options -> Automatic Similar Thread search

4. Ensure vB config.php usepconnect = 0 and phpadsnew is updated to latest stable version and in settings has persistent connections disabled

Here is the zend section of my php.ini

[Zend]
zend_extension = /usr/local/ioncube/ioncube_loader_lin_4.4.so
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.0.0
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.0.0
zend_optimizer.version=3.0.0
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so


but i installed ioncube for one of the special hack that i have so must i remove this line too?


zend_extension = /usr/local/ioncube/ioncube_loader_lin_4.4.so


If i remove it ioncube wont work....

if you need ioncube then don't install APC as it won't work together

next time you have cpu load type and post output for these 2 commands

mysqladmin -u root -p var ext ver proc > stats.txt

open the stats.txt file to copy and paste it's contents.

definitely looks like the centOS + 2.6.9-34 kernel bug to me http://www.vbulletin.com/forum/showthread.php?t=171071

I told my host to upgrade kernel...

Also they said that high apache loads can cause this also. I had a look at the apache's job by writing its pid ( forgot its command) but everything seems fine.

I thought it can be because of phpadsnew but couldnt be sure about it...


edit : the load at server was like 33 and when i type service httpd restart (restart apache) load start to decrease.... dont know if it is apache or that damn kernel bug...

i see you have mod_gzip enabled in apache, make sure vB admincp's gzip compression is disabled as having both enabled = higher cpu loads too
