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.

       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.
