Jump to Virtual / Dedicated Serverâ Ž: In this hosting scenario you have control over your own server. The server might be a dedicated piece of hardware
http://codex.wordpress.org/WordPress_OptimizationHOME |
Hi eva2000, I got this new Windows server, so not sure whether you can help me, I guess you can only help me with the mysql optimisation? Correct me if I am wrong, anyway here's the informations you need.
1. Is this on dedicated or shared virual server. If shared, how many sites share this server (ask web host if needed)
Dedicated server owned by me. There is 5 website currently on this server and will slowly increase.
2. your server specs. For example:
cpu speed/type single or dual cpus): Intel Pentium 4 3.2Ghz with HT
how much memory installed: 2G ram
hard drive type/configuration: 160G SATA hdd
linux distributor or windows version: Windows 2003 Server Standard Edition
apache/IIS version: IIS 6
PHP version: php 4.4.0
MySQL version: mysql 4.1.13a
3. if you use mysql 4.x instead of mysql 3.23.x, do you have any innodb type databases/tables on your server?
Yes, some database/tables using innodb
4. if possible how mysql was compiled/installed
Download and installed windows version of mysql
5. your top stats
No top command for windows?
6. your mysql configuration variables

8. is your vB the only thing on the server? or other scripts & sites which utilise php and mysql?
Yes, there is also phpbb and ipb
9. how many average and max concurrent users on your vB forum ? and what your cookie timeout is ?
Currently below 100 but will be expecting 100-250 users soon. Cookie timeout is 3600.
10. phpinfo.php
http://www.lovebites.sg/info/
11. Not applicable for my server since using Windows
12. what version of vB are you running ?
2 of my site both using v3.5.3
13. Not applicable for my server since using Windows
Hope to hear from you soon eva2000! Thanks!
Well a few things to do in this order
1. Upgrade MySQL server to 4.1.16
2. Upgrade PHP to 4.4.2 if you use phpadsnew make sure to update to phpadsnew 2.0.7 to work with PHP 4.4.1/4.4.2
3. Edit /etc/my.cnf and place the following mysql server settings in /etc/my.cnf and restart mysql server afterwards
[mysqld]

just a curious qns eva2000, not sure if you can help... how do i upgrade mysql on windows? do i just download the executable to the server and install it and it will auto detect existing version and upgrade accordingly?
Same goes for php?
by the way eva2000, i notice that the my.cnf you mention above... can I use the same settings you recommend for my Windows version of MySQL (using my.ini instead of my.cnf)
No. Never use the installer to install mysql or php. Install manually. Same for upgrading.
I just wrote this article for installing mysql (http://adminreports.com/archives/2006/01/24/installing-mysql.html) on Windows.
You should be able follow those directions to upgrade mysql or you could wait until I finish my upgrading mysql on Windows Server article tommorrow.
i found another article on how to upgrade mysql... just like what you mention. Thanks!
So same goes for PHP? Had to installed it manually?
remove sync_frm = 1 that's not needed
for innodb is that some tables ? what uses innodb ?
by the way eva2000, i notice that the my.cnf you mention above... can I use the same settings you recommend for my Windows version of MySQL (using my.ini instead of my.cnf)
Yes you can. Just add that to my.ini. Make sure you leave you data and mysql path instact.
Install manually. I also have PHP install on Windows article on the same site.
the safest way to convert would be to mysqldump the innodb databases out to sql file
then while default storage engine is set at MYISAM in my.cnf, create new empty mysql databases and import the mysqldump'd sql file into them again...
hmm can i leave my existing database alone then? (there is only 2-3 of them)
by the way does innodb performs better then myisam? other then taking up resources...
Weird... i use eva2000's configuration... i cannot connect to two database...
safe-show-database
old_passwords
sync_frm = 1
shows as invalid option...
so i corrected old_passwords to old-passwords but still have difficulty connecting to database so in the end i use back the old original my.ini
whats wrong here?
you need to add back the innodb config settings in my.cnf try this
if you really don't need innodb change back to myisam format as you won't use as much memory/disk/server resources as innodb does
Hmm just wondering why my vbuletin uses innodb?
Is it because my original settings has default-storage-engine=INNODB?
I also noticed that the configuration file (where i set my database for my vbulletin) got this new parameter of pointing to a my.ini or my.cnf, do i need to turn it on?
remove sync_frm = 1 that's not needed
for innodb is that some tables ? what uses innodb ?
hi eva2000,
I still got problem connecting (vbulletin got database error so after changing back to default my.ini, it can runs again) even though I use the below :

i got database using innodb... even my vbulletin database is using innodb. I notice there is a setting skip-innodb. Could that be the problem?

yeah you can leave the innodb databases alone but would need to move the data files outside of mysql data directory so you can disable innodb i.e. /var/lib/mysql/dbname
where dbname is the name of innodb database
MyISAM performance is faster than innodb.. only benefit innodb has for vB use is helps for mysql table locking if there's high concurrency connections to the same database table name i.e. post/postindex/thread tables
you need to add back the innodb config settings in my.cnf try this

okies things working good now. Thanks eva2000!
PS: How do i convert those database that is using innodb to myisam now...
I have found that what works in my.ini for Linux won't work well with Windows. Here is what I have in mine. My hardware specs are the same as your except I have 3.0 processors.
Just change the paths and this one should work well for you.
cool, Thanks! By the way i got innodb tables... do i need to add anything on top of your settings?
No. Never use the installer to install mysql or php. Install manually. Same for upgrading.
I just wrote this article for installing mysql (http://adminreports.com/archives/2006/01/24/installing-mysql.html) on Windows.
You should be able follow those directions to upgrade mysql or you could wait until I finish my upgrading mysql on Windows Server article tommorrow.
