seata nacos
1.搭建seata环境
1).下载seata
下载地址:https://github.com/seata/seata/releases
我下载的是1.4.0版本
2).搭建数据库
seata-server
搭建seata应用前,需要创建一个数据库。数据库名为: seata
但是从seata1.0.0版本(好像是这个)开始,不再自带数据库脚本。因此需要下载source文件,或者到github上找。
数据库脚本地址:https://github.com/seata/seata/blob/develop/script/server/db/mysql.sql。
-- -------------------------------- 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), `table_name` VARCHAR(32), `pk` VARCHAR(36), `gmt_create` DATETIME, `gmt_modified` DATETIME, PRIMARY KEY (`row_key`), KEY `idx_branch_id` (`branch_id`) ) ENGINE = InnoDB DEFAULT CHARSET = utf8;
seata-server的数据库最终是这样:
seata-client
seata-client为自己测试的服务,可自由发挥。但是每个事务的数据库中都要添加一张undo_log表。
-- for AT mode you must to init this sql for you business database. the seata server not need it. CREATE TABLE IF NOT EXISTS `undo_log` ( `branch_id` BIGINT(20) NOT NULL COMMENT 'branch transaction id', `xid` VARCHAR(100) NOT NULL COMMENT 'global transaction id', `context` VARCHAR(128) NOT NULL COMMENT 'undo_log context,such as serialization', `rollback_info` LONGBLOB NOT NULL COMMENT 'rollback info', `log_status` INT(11) NOT NULL COMMENT '0:normal status,1:defense status', `log_created` DATETIME(6) NOT NULL COMMENT 'create datetime', `log_modified` DATETIME(6) NOT NULL COMMENT 'modify datetime', UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`) ) ENGINE = InnoDB AUTO_INCREMENT = 1 DEFAULT CHARSET = utf8 COMMENT ='AT transaction mode undo table';

3).配置:配置的是 conf下的file.conf与registry.conf
2、启动seata
windows:
直接双击seata-server.bat:
