使用和管理 NDB 集群需要几个专门的程序，本章将对此进行说明。我们将讨论这些程序在 NDB 集群中的用途、如何使用这些程序，以及它们各自的启动选项。Using and managing an NDB Cluster requires several specialized programs, which we describe in this chapter. We discuss the purposes of these programs in an NDB Cluster, how to use the programs, and what startup options are available for each of them.
这些程序包括 NDB Cluster 数据、管理和 SQL 节点进程（ndbd、ndbmtd、ndb_mgmd 和 mysqld）以及管理客户端（ndb_mgm）。These programs include the NDB Cluster data, management, and SQL node processes (ndbd, ndbmtd, ndb_mgmd, and mysqld) and the management client (ndb_mgm).
有关将 mysqld 用作 NDB 集群进程的信息，请参阅 第 25.6.10 节，“MySQL 服务器在 NDB 集群中的使用”。For information about using mysqld as an NDB Cluster process, see Section 25.6.10, “MySQL Server Usage for NDB Cluster”.
其他 NDB 实用程序、诊断程序和示例程序包含在 NDB Cluster 发行版中。这些包括 ndb_restore、ndb_show_tables 和 ndb_config。这些程序在本节中也有介绍。Other NDB utility, diagnostic, and
example programs are included with the NDB Cluster distribution.
These include ndb_restore,
ndb_show_tables, and
ndb_config. These programs are also covered in
this section.
