5.1.3 服务器选项、系统变量和状态变量参考

下表列出了适用于 mysqld.

该表在一个统一列表中列出了命令行选项 (Cmd-line)、配置文件中有效的选项 (Option file)、服务器系统变量 (System Var) 和状态变量 (Status var)，并指示每个选项的位置或变量有效。如果在命令行或选项文件中设置的服务器选项与相应系统变量的名称不同，则变量名称会紧邻相应选项下方注明。对于系统变量和状态变量，变量的范围 (Var Scope) 是 Global、Session 或两者。有关选项和变量的设置和使用的详细信息，请参阅相应项目的说明。在适当的情况下，提供有关该项目的更多信息的直接链接。

有关此表特定于 NDB Cluster 的版本，请参阅 第 21.4.2.5 节，"NDB Cluster mysqld 选项和变量参考"。
