可以通过 SQL 接口使用本节描述的语句控制复制。语句分为控制源服务器的组、控制副本服务器的组以及可应用于任何复制服务器的组。Replication can be controlled through the SQL interface using the statements described in this section. Statements are split into a group which controls source servers, a group which controls replica servers, and a group which can be applied to any replication servers.
