上传配置至Nacos配置中心

从v1.4.2版本开始，已支持从一个Nacos dataId中获取所有配置信息,需要在nacos新建配置（dataId为seata.properties）

初始化数据库表结构（mysql版本）

• 创建数据库实例

CREATE DATABASE seata default character set utf8 collate utf8_general_ci; # 基于seata的数据库实例对象
GRANT ALL PRIVILEGES on seata.* to 'lixing'@'%'; # 为用户lixing赋予操作数据库实例seata的权限
FLUSH PRIVILEGES; # 刷新权限列表

• 创建服务端 global_table、branch_table、lock_table 表

-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
    `xid`                       VARCHAR(128) NOT NULL,
    `transaction_id`            BIGINT,
    `status`                    TINYINT      NOT NULL,
    `application_id`            VARCHAR(32),
    `transaction_service_group` VARCHAR(32),
    `transaction_name`          VARCHAR(128),
    `timeout`                   INT,
    `begin_time`                BIGINT,
    `application_data`          VARCHAR(2000),
    `gmt_create`                DATETIME,
    `gmt_modified`              DATETIME,
    PRIMARY KEY (`xid`),
    KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
    KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;
--
-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
    `branch_id`         BIGINT       NOT NULL,
    `xid`               VARCHAR(128) NOT NULL,
    `transaction_id`    BIGINT,
    `resource_group_id` VARCHAR(32),
    `resource_id`       VARCHAR(256),
    `branch_type`       VARCHAR(8),
    `status`            TINYINT,
    `client_id`         VARCHAR(64),
    `application_data`  VARCHAR(2000),
    `gmt_create`        DATETIME(6),
    `gmt_modified`      DATETIME(6),
    PRIMARY KEY (`branch_id`),
    KEY `idx_xid` (`xid`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;
--
-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
    `row_key`        VARCHAR(128) NOT NULL,
    `xid`            VARCHAR(96),
    `transaction_id` BIGINT,
    `branch_id`      BIGINT       NOT NULL,
    `resource_id`    VARCHAR(256),

    `gmt_modified`   DATETIME,
    PRIMARY KEY (`row_key`),
    KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

• 创建客户端（即每个微服务） undo_log 表（涉及到分布式事务的微服务的数据库实例都要创建）

-- for AT mode you must to init this sql for you business database. the seata server not need it.
CREATE TABLE `undo_log` (
  `branch_id` bigint NOT NULL COMMENT '分支事务id',
  `xid` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '全局事务id',
  `context` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '撤消日志上下文',
  `rollback_info` longblob NOT NULL COMMENT '回滚信息',
  `log_status` int NOT NULL COMMENT '0:正常状态，1:防御状态',
  `log_created` datetime NOT NULL COMMENT '创建时间',
  `log_modified` datetime NOT NULL COMMENT '修改时间',
  UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='AT transaction mode undo table';
