my.cnf question
| Posted by Neso, 01-18-2010, 06:24 AM |
| This is my.cnf on my dedicated server, AMD Quad Core 9600, 6 GB RAM Cpanel/WHM, PHP 5.2.12, Apache 2.2, MySQL 5.
My question is do you think that I should change something.

| Remove the following from my.cnf
skip-innodb
innodb tables won't work if you turn off innodb on your server.
skip-networking
Only if any client is accessing databases on stored on your server from a remote server.
Change the following:
max_user_connections
Set it to 20-30 if you are planning to host hundreds of websites. If you are hosting a couple of websites then the current value is fine.
wait_timeout
it defines the number of seconds a mysql thread waits in idle state. If it is set to too low and if your queries has delays in executing, then Mysql will keep dropping the connection. I would recommend it to set to a higher value.
Rest looks good. Don't forget to restart the mysql service once you make the changes.

| The configuration looks like one which is optimized by els
els uses a generic template. Try using a mysql tuner to get suggestions more suitable for your server.

| The current one looks good ..if any issues you just need to optimize the mysql-cache and the number of connection which will do.

| If you still have problems, there are numerous mysql optimizer scripts available. Just google it and download one into your server and execute. Please note that it can give about accurate results if the mysql is running for the past 48 hours.
