Optimize MySQL for Low Memory Use

MySQL is a light database engine compared tomany of it’s rivals, but for some reason theDebian MySQL-server package contains a setup that makes it very heavy and memory consuming. The Debian version of becomes memory consuming because it comes with config file where MySQL’s most memory consuming and seldom used storage engine InnoDB is enable. As result of this the MySQL server instance uses around 100MB of memory while almost idle.

And here comes the optimization tip.

Since the InnoDB storage engine is used very seldom it can be disable in most cases and let the server save almost about 100MB of memory.

To disable to InnoDB storage engine add this to my.cnf (the default MySQLconfiguration files) in /etc/mysql/
skip-innodb
