一、版本說(shuō)明

https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E

?二、建立Seata Server數(shù)據(jù)庫(kù)（TC-帶頭大哥的數(shù)據(jù)庫(kù)）

https://github.com/apache/incubator-seata/tree/v1.6.1/script/server/db

三、業(yè)務(wù)庫(kù)建表

在訂單業(yè)務(wù)數(shù)據(jù)庫(kù)和庫(kù)存業(yè)務(wù)數(shù)據(jù)庫(kù)里分別添加下表

https://github.com/apache/incubator-seata/blob/v1.6.1/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       NOT NULL COMMENT 'branch transaction id',`xid`           VARCHAR(128) 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 = InnoDBAUTO_INCREMENT = 1DEFAULT CHARSET = utf8mb4 COMMENT ='AT transaction mode undo table';

?四、安裝Seata-Server

參考https://seata.apache.org/zh-cn/docs/v1.6/ops/deploy-by-docker-compose/#nacos%E6%B3%A8%E5%86%8C%E4%B8%AD%E5%BF%83db%E5%AD%98%E5%82%A8

?4.1 虛擬機(jī)里新建一個(gè)/opt/seate/seata-server文件夾，在seate文件夾下新建一個(gè)docker-compose.yml 文件

docker-compose.yml 文件如圖所示。

version: "3.1"
services:seata-server:image: seataio/seata-server:1.6.1ports:- "7091:7091"- "8091:8091"environment:- STORE_MODE=db# 以SEATA_IP作為host注冊(cè)seata server- SEATA_IP=192.168.11.82- SEATA_PORT=8091volumes:- "/usr/share/zoneinfo/Asia/Shanghai:/etc/localtime"        #設(shè)置系統(tǒng)時(shí)區(qū)- "/usr/share/zoneinfo/Asia/Shanghai:/etc/timezone"  #設(shè)置時(shí)區(qū)# 假設(shè)我們通過(guò)docker cp命令把資源文件拷貝到相對(duì)路徑`./seata-server/resources`中# 如有問(wèn)題，請(qǐng)閱讀上面的[注意事項(xiàng)]以及[使用自定義配置文件]- "./seata-server/resources:/seata-server/resources"

4.2 運(yùn)行容器

版本和配置文件保持一致

目的是找到 id

? docker run -d --rm seataio/seata-server:1.6.1

?拷貝文件

利用id拷貝文件（將容器里的文件拷貝到宿主機(jī)）

docker cp 07d0:/seata-server/resources /opt/seata/seata-server/resources

?修改application.yml文件內(nèi)容

?

application.yml?

4.3 在nacos里配置seata的相關(guān)信息

只需修改數(shù)據(jù)庫(kù)相關(guān)配置即可,數(shù)據(jù)庫(kù)名和第二個(gè)大標(biāo)題建的保持一致 seata_tc

4.4 啟動(dòng)

1.先cd 到seata文件夾，再執(zhí)行下面的命令

docker-compose up -d

去nacos里查看服務(wù)是否啟動(dòng)
