Having a separate slave server separate from everything else just seems like the clean way. Having a slave on every web machine will add a load to each web server necessitating better physical machines (since every change to the db has to replicate to N machines rather than just 1 machine).
Both ways will work fine since <100 queries/sec is not pushing any sort of network envelopes or anything. -----Original Message----- From: Eric Anderson [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 30, 2002 11:22 AM To: Adam Nelson Cc: [EMAIL PROTECTED] Subject: RE: MySQL hardware concerns On Tue, 30 Jul 2002, Adam Nelson wrote: > Seems to me like a better architecture might be: > > N apache servers with mysql clients > 1 Master Mysql Server > 1 Slave Mysql Server/admin/backup server > > If you have 5 slave servers (one on each apache server), that would > cause much more traffic on the internal network than each apache > machine just being a client and running the queries on the master > server.

And if you '--skip-networking' the mysql slaves aren't exposed to the Net either (rightly so). Personally, I think having the data pushed out to the slave servers is the way to go, since if something happens to the master server (even a reboot) the slaves will continue to serve pages because of the local data. -- ------------------------------------------------------------------------ - Eric Anderson Wild Web Amateurs CyberIron Bodybuilding ICQ 3849549 http://www.wildwebamateurs.com http://www.cyberiron.com San Diego, CA <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> ------------------------------------------------------------------------ - "You've got the brain and talent to do anything you want, and when you do, I'll be right there to borrow money from you!" -- Bart Simpson --------------------------------------------------------------------- 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?
