同步两个DB之间的schema,配置如下: sourceHost=127.0.0.1:3306 sourceUser=root sourcePass=123123123 sourceSchema=mystique_db sourceCharset=utf8

targetHost=127.0.0.1:3306 targetUser=root targetPass=123123123 targetSchema=mystique_test targetCharset=utf8

autoExecute=YES //此处表明自动同步

原理: 通过捞取information_schema来比较source_schema和target_schema(可在不同实例)的表结构是否一致, 如果target_schema没有则这张表则创建, 如果target_schema表里面没有这个字段则alter add(保证顺序), 如果表里面有这个字段、但属性不一样则alter change, 另外还同步索引的元数据. 可以指定进行自动执行,也可以指定打印出对应的执行语句,语句如下所例: alter table mystique_test.t_test_3 change id id bigint(20) NOT NULL AUTO_INCREMENT COMMENT '' alter table mystique_test.t_test_3 add index (name) alter table mystique_test.t_test_3 drop index name_id alter table mystique_test.t_test_3 add id_2 varchar(50) NULL DEFAULT '' COMMENT '' after name
