NAME
       mysqld -	the MySQL server

SYNOPSIS
       mysqld [options]

DESCRIPTION
       mysqld, also known as MySQL Server, is the main program that does most
       of the work in a	MySQL installation. MySQL Server manages access	to the
       MySQL data directory that contains databases and	tables.	The data
       directory is also the default location for other	information such as
       log files and status files.

	   Note
	   Some	installation packages contain a	debugging version of the
	   server named	mysqld-debug. Invoke this version instead of mysqld
	   for debugging support, memory allocation checking, and trace	file
	   support (see	Section	28.5.1.2, "Creating Trace Files").

       When MySQL server starts, it listens for	network	connections from
       client programs and manages access to databases on behalf of those
       clients.

       The mysqld program has many options that	can be specified at startup.
       For a complete list of options, run this	command:

	   shell> mysqld --verbose --help

       MySQL Server also has a set of system variables that affect its
       operation as it runs. System variables can be set at server startup,
       and many	of them	can be changed at runtime to effect dynamic server
       reconfiguration.	MySQL Server also has a	set of status variables	that
       provide information about its operation.	You can	monitor	these status
       variables to access runtime performance characteristics.

       For a full description of MySQL Server command options, system
       variables, and status variables,	see Section 5.1, "The MySQL Server".
       For information about installing	MySQL and setting up the initial
       configuration, see Chapter 2, Installing	and Upgrading MySQL.
