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.

NAME

       mysql_install_db - initialize MySQL data directory

SYNOPSIS

       mysql_install_db [options]

DESCRIPTION

       mysql_install_db initializes the MySQL data directory and creates the system tables that it contains, if they do not exist.

       To invoke mysql_install_db, use the following syntax:

	   shell> mysql_install_db [options]

       Because the MySQL server, mysqld, needs to access the data directory when it runs later, you should either run mysql_install_db from the
       same account that will be used for running mysqld or run it as root and use the --user option to indicate the user name that mysqld will
       run as. It might be necessary to specify other options such as --basedir or --datadir if mysql_install_db does not use the correct
       locations for the installation directory or data directory. For example:

	   shell> bin/mysql_install_db --user=mysql 
		    --basedir=/opt/mysql/mysql 
		    --datadir=/opt/mysql/mysql/data

       mysql_install_db needs to invoke mysqld with the --bootstrap and --skip-grant-tables options (see Section 2.3.2, "Typical configure
       Options"). If MySQL was configured with the --disable-grant-options option, --bootstrap and --skip-grant-tables will be disabled. To handle
       this, set the MYSQLD_BOOTSTRAP environment variable to the full path name of a server that has all options enabled.  mysql_install_db will
       use that server.

       mysql_install_db supports the following options, which can be specified on the command line or in the [mysql_install_db] and (if they are
       common to mysqld) [mysqld] option file groups.

       o   --basedir=path

	   The path to the MySQL installation directory.

       o   --force

	   Cause mysql_install_db to run even if DNS does not work. In that case, grant table entries that normally use host names will use IP
	   addresses.

       o   --datadir=path, --ldata=path

	   The path to the MySQL data directory.

       o   --rpm

	   For internal use. This option is used by RPM files during the MySQL installation process.

       o   --skip-name-resolve

	   Use IP addresses rather than host names when creating grant table entries. This option can be useful if your DNS does not work.

       o   --srcdir=path

	   For internal use. The directory under which mysql_install_db looks for support files such as the error message file and the file for
	   populating the help tables. This option was added in MySQL 5.1.14.

       o   --user=user_name

	   The login user name to use for running mysqld. Files and directories created by mysqld will be owned by this user. You must be root to
	   use this option. By default, mysqld runs using your current login name and files and directories that it creates will be owned by you.

       o   --verbose

	   Verbose mode. Print more information about what the program does.

       o   --windows

	   For internal use. This option is used for creating Windows distributions.
