在Mysql库中创建seata服务端需要的表

drop table if exists `global_table`;
create table `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`)
);


drop table if exists `branch_table`;
create table `branch_table` (
  `branch_id` bigint not null,
  `xid` varchar(128) not null,
  `transaction_id` bigint ,
  `resource_group_id` varchar(32),
  `resource_id` varchar(256) ,
  `lock_key` varchar(128) ,
  `branch_type` varchar(8) ,
  `status` tinyint,
  `client_id` varchar(64),
  `application_data` varchar(2000),
  `gmt_create` datetime,
  `gmt_modified` datetime,
  primary key (`branch_id`),
  key `idx_xid` (`xid`)
);


drop table if exists `lock_table`;
create table `lock_table` (
  `row_key` varchar(128) not null,
  `xid` varchar(96),
  `transaction_id` long ,
  `branch_id` long,
  `resource_id` varchar(256) ,
  `table_name` varchar(32) ,
  `pk` varchar(36) ,
  `gmt_create` datetime ,
  `gmt_modified` datetime,
  primary key(`row_key`)
);

修改seata注册文件conf/registry.conf，注册到nacos上

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos "  #修改为nacos

  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"

    #如果nacos开启了权限控制，请配置用户名密码
    username = ""
    password = ""
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"  #修改为nacos

  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = ""
    group = "SEATA_GROUP"

    #如果nacos开启了权限控制，请配置用户名密码
    username = ""
    password = ""
  }
}

新建config.txt，修改事务分组，修改数据库连接信息

service.vgroupMapping.my_test_tx_group=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true
store.db.user=username
store.db.password=password
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

下载seata源码

推送上面配置的seata.txt配置到nacos，请先开启nacos，执行推送配置脚本

seata推送脚本

1.如果推送失败，请检查nacos是否开启了权限控制，请关闭nacos的全控制，重新推送
2.查看nacos对应的IP地址，修改推送脚本中nacos的地址即可

启动seata

sh seata-serrver.sh >seata.log &

seata启动完成之后，到nacos上进行查看seata服务
