I agree completely with Egor! You should not be killing your processes to solve load problems. If there is a load problem 1) You need to write your applications better, 2) you need to have a better database structure, 3) you need to analyze where indexes would help you, or 4) you need a more powerful machine. I know Apache has directives in the config file to tell it the maximum number of daemons to run.
As in real life, so it is with computers: killing never solves the real problem, it just make it go away for a while. So, tune your app, tune Apache, tune MySQL, or get a bigger machine. But DO NOT implement your "kill when load is high" solution. BTW, enough "temporary glitches" and you won't have users any more. People like a trouble-free web site: unreliability is perceived as being unprofessional, unprofessional web sites lose clients in a hurry. j----- k----- On Thursday 10 October 2002 07:56, Egor Egorov wrote: > BC> I have a script that runs every minute to deterimine > BC> if the load is above a certain value (or if swap is > BC> high) and if so, it kills all the httpd processes, > BC> does /etc/rc.d/init.d/mysql stop > > BC> The script then starts everything back up again. > BC> I am curious if there is a better way to restart mysql > > I can say that solving performance/load problems by resetting > SQL server or web server is a totally wrong solution. > > The Right Way(tm) is to fine-tune both MySQL and Apache to fit in > memory/CPU load - this way you'll get much better performance and > reliability! > > So you can take a look at > http://www.mysql.com/doc/en/MySQL_Optimisation.html -- Joshua Kugler, Information Services Director Associated Students of the University of Alaska Fairbanks [EMAIL PROTECTED], 907-474-7601 --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
