MySQL is a Structured Query Language (SQL) server that runs on Red Hat Linux, as well as other operating systems. Using a start-up script (/etc/init.d/mysqld) and a configuration file (/etc/my.cnf), you can quickly get a MySQL server up and running.
With tools such as the mysqladmin and mysql commands, you can administer the MySQL server and create databases and tables that are as simple or complex as you need. During mysql sessions, you can modify the structure of your database tables or add, update, and delete database records. You have a variety of options for querying data and sorting the output. You also have a lot of control over who can access your database tables and what privileges users have to modify, add to, or delete from the databases you control.
