    MySQL程序概述

    There are many different programs in a MySQL installation. This section provides a brief overview of them. Later sections provide a more detailed description of each one, with the exception of MySQL Cluster programs. Each program's description indicates its invocation syntax and the options that it supports. Section 19.4, “MySQL Cluster Programs”, describes programs specific to MySQL Cluster.

    Most MySQL distributions include all of these programs, except for those programs that are platform-specific. (For example, the server startup scripts are not used on Windows.) The exception is that RPM distributions are more specialized. There is one RPM for the server, another for client programs, and so forth. If you appear to be missing one or more programs, see Chapter 2, Installing and Upgrading MySQL, for information on types of distributions and what they contain. It may be that you have a distribution that does not include all programs and you need to install an additional package.

    Each MySQL program takes many different options. Most programs provide a —help option that you can use to get a description of the program's different options. For example, try mysql —help.

    You can override default option values for MySQL programs by specifying options on the command line or in an option file. See Section 5.2, “Using MySQL Programs”, for general information on invoking programs and specifying program options.

    The MySQL server, mysqld, is the main program that does most of the work in a MySQL installation. The server is accompanied by several related scripts that assist you in starting and stopping the server:
