配置Nacos

拷贝配置YAML

docker cp seata-server:/seata-server/resources /usr/local/workspace/seata/resources

修改配置YAML

初始化 Nacos 的 Seata 配置

下载源码：https://github.com/seata/seata

参考：https://github.com/seata/seata/tree/develop/script/config-center

sh ${SEATAPATH}/script/config-center/nacos/nacos-config-interactive.sh

提示1：缺少配置项：service.vgroupMapping.default，自行增加到nacos中。

Data id: service.vgroupMapping.default
Group: SEATA_GROUP
配置内容: default

提示2：我这里出现了序列化问题，修改配置：client.undo.logSerialization

Data id: client.undo.logSerialization
Group: SEATA_GROUP
配置内容: kryo

项目引用 kryo 依赖包。注意版本号对应，避免依赖包包冲突。我这里使用的是 seata-server-1.4.2

<dependency>
  <groupId>com.esotericsoftware</groupId>
  <artifactId>kryo</artifactId>
  <version>4.0.2</version>
</dependency>
<dependency>
  <groupId>de.javakaffee</groupId>
  <artifactId>kryo-serializers</artifactId>
  <version>0.42</version>
</dependency>

运行Seata注册到Nacos

docker run -d --name seata -p 8091:8091 \
    -e SEATA_CONFIG_NAME=file:/seata-server/registry.conf \
    -e SEATA_IP=IP \
    -e SEATA_PORT=8091 \
    -v /usr/local/workspace/seata/resources:/seata-server/resources \
    --restart always seataio/seata-server

业务数据库增加表

CREATE TABLE `undo_log`
(
    `id`            bigint(20)   NOT NULL AUTO_INCREMENT,
    `branch_id`     bigint(20)   NOT NULL,
    `xid`           varchar(100) NOT NULL,
    `context`       varchar(128) NOT NULL,
    `rollback_info` longblob     NOT NULL,
    `log_status`    int(11)      NOT NULL,
    `log_created`   datetime     NOT NULL,
    `log_modified`  datetime     NOT NULL,
    `ext`           varchar(100) DEFAULT NULL,
    PRIMARY KEY (`id`),
    UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDB
