2.创建映射表

首先在Master机器上建立projects表，我们只需要将每个agent数据库中建立映射表projects

CREATE TABLE `projects` (

`project_id` INT(11) NOT NULL AUTO_INCREMENT,

`project_code` VARCHAR(50) NOT NULL,

`test_code` VARCHAR(50) NOT NULL,

`create_time` BIGINT(11) NULL DEFAULT NULL,

`result` VARCHAR(255) NULL DEFAULT NULL,

`ts` BIGINT(11) NOT NULL,

PRIMARY KEY (`id`)

)

COLLATE='utf8_general_ci'

ENGINE=FEDERATED

CONNECTION='mysql://user:password@202.59.232.211:3306/testdb/tb_projects_tests';
