创建配置文件夹
mkdir -p /home/${username}/docker/seata/resources
启动临时容器获取配置文件后删除临时容器
docker run -d -p 8091:8091 -p 7091:7091 --name seata-server seataio/seata-server
docker cp seata-server:/seata-server/resources/. /home/${username}/docker/seata/resources
docker rm -f seata-server
修改application.yml配置文件

导入Nacos配置文件

找到对应版本的配置文件
需要配置ip + 端口 + 用户名 + 密码

坑点
jdk需要1.8，高版本17报错
seata版本1.7.1可行，高版本报错
SpringBoot配置
seata:
enabled: true
# 事务组的名称，对应service.vgroupMapping.default_tx_group=xxx中配置的default_tx_group
tx-service-group: default_tx_group # 需要与下方一致
# 配置事务组与集群的对应关系
service:
vgroup-mapping:
# default_tx_group为事务组的名称，default为集群名称(与registry.conf中的一致)
default_tx_group: default # 需要与上方一致
disable-global-transaction: false
registry:
type: nacos
nacos:
application: seata-server
server-addr: ${eblog.cloud.nacos.server-addr}
group: DEFAULT_GROUP
namespace: ""
username: nacos
password: nacos
# registry.conf中，配置cluster名称
cluster: default
data-source-proxy-mode: XA
使用AT模式
需要在每个RM数据库中添加undolog
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for undo_log
-- ----------------------------
DROP TABLE IF EXISTS `undo_log`;
CREATE TABLE `undo_log` (
`branch_id` bigint(20) 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 '上下文',
`rollback_info` longblob NOT NULL COMMENT '回滚信息',
`log_status` int(11) NOT NULL COMMENT '状态，0正常，1全局已完成',
`log_created` datetime(6) NOT NULL COMMENT '创建时间',
`log_modified` datetime(6) NOT NULL COMMENT '修改时间',
UNIQUE INDEX `ux_undo_log`(`xid`, `branch_id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = 'AT transaction mode undo table' ROW_FORMAT = Compact;
SET FOREIGN_KEY_CHECKS = 1;
然后修改springboot的application.yml
