1、业务文件sql（mysql）
==把一下sql创建到业务数据库中== sql 文件地址 ---> https://github.com/seata/seata/blob/1.4.0/script/client/at/db/mysql.sql
-- 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',

UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDB
AUTO_INCREMENT = 1
DEFAULT CHARSET = utf8 COMMENT ='AT transaction mode undo table';
2、seata 文件sql
==把一下sql 新键到一个数据库中== sql 文件地址 ---> https://github.com/seata/seata/blob/1.4.0/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),

`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`

) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
3、seata服务端
- 下载后直接解压 github.com/seata/seata…
- 修改conf/registry.conf如下
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "nacos"
loadBalance = "RandomLoadBalance"
loadBalanceVirtualNodes = 10
nacos {
namespace = ""
serverAddr = "192.168.0.1"
group = "SEATA_GROUP"
username: "name" #登录账号
password: "pwd" #登录密码
}
}
config {
# file、nacos 、apollo、zk、consul、etcd3
type = "nacos"
nacos {
namespace = ""
serverAddr = "192.168.0.1"
group = "SEATA_GROUP"
username: "name"
password: "pwd"
}
}
4、seata nacos配置
创建config.txt文件夹
service.vgroupMapping.my_test_tx_group=default
service.default.grouplist=127.0.0.1:8091
service.enableDegrade=false
service.disableGlobalTransaction=false
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://192.168.0.1:3306/mole_seata?useUnicode=true
store.db.user=seata
store.db.password=seata
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000
配置提交
脚本文件如下 github.com/seata/seata…
#运行
sh ${SEATAPATH}/script/config-center/nacos/nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -t 5a3c7d6c-f497-4d68-a71a-2e5e3340b3ca -u username -w password

6、applicatio.yml 配置
这边提供地址，有需要的可以看下https://github.com/seata/seata/blob/1.4.0/script/client/spring/application.yml
我这边删除了很多配置 nacos配置为例
seata:
enable-auto-data-source-proxy: false
application-id: 项目名
service:
vgroup-mapping:
my_test_tx_group: default
grouplist:
default: 192.168.0.163:8091 #seata服务端ip
enable-degrade: false
disable-global-transaction: false
config:
type: nacos
nacos:
namespace:
serverAddr: 192.168.0.1:8848 #nacos服务端ip
group: SEATA_GROUP
username: "name" #登录账号
password: "pwd" #登录密码
registry:
type: nacos
nacos:
application: seata-server
server-addr: 192.168.0.1:8848
group : "SEATA_GROUP"
namespace:
username: "name"
password: "pwd"
