All MySQL programs take many different options. However, every MySQL program provides a --help option that you can use to get a description of the program's options. For example, try mysqld --help.
You can override default options for all standard programs by specifying options on the command line or in an option file. Program Options.
The following list briefly describes the server-related MySQL programs:
mysqld | The SQL daemon (that is, the MySQL server). To use client programs, this program must be running, because clients gain access to databases by connecting the the server. |
mysqld_max | A version of the server that includes additional features. |
mysqld_safe | A server startup script. mysqld_safe attempts to start mysqld_max if it exists, and mysqld otherwise. |
mysql.server | A server startup script. This scripts is used on systems that use run directories containing scripts that start system services for particular run levels. |
mysqld_multi | A server startup script that can start or stop multiple servers installed on the system. |
mysql_install_db | This script creates the MySQL grant tables with default privileges. It is usually executed only once, when first installing MySQL on a system. |
mysql_fix_privilege_tables | This script is used after an upgrade install operation, to update the grant tables with any changes that were made in newer versions of MySQL since the previous install operation. |
There are several other programs that also are run on the server host:
myisamchk | Utility to describe, check, optimize, and repair MySQL tables. Because myisamchk has many functions, it is described in its own chapter. See MySQL Database Administration. |
make_binary_distribution | Makes a binary release of a compiled MySQL. This could be sent by FTP to /pub/mysql/Incoming on support.mysql.com for the convenience of other MySQL users. |
mysqlbug | The MySQL bug report script. This script can be be used to send a bug report to the MySQL list. (You can also visit http://bugs.mysql.com/ to file a bug report online.) |
