Hi Any one can assist me in Optimizing mysql Why because i am facing the high server load because of the mysql often
There are many tools out there that will help you. You can also increase your RAM to help. Take a look at my blog post regarding a couple of different scripts that will help you along: http://solidservers.ca/2009/07/tuning-tweaking-mysql/ One thing to note, changes that are made need at least a day or more running to truly see if the results are what you are trying to achieve.
Log the slow queries (search google on how to do this), then use EXPLAIN to see what's causing them to be slow, then add indices or optimize your SQL statements.
