docker-compose.yaml

这里采用 docker-compose方式启动,其余方式大同小异,docker会更加干净方便,docker-compose.yaml文件内容如下:

services:
seata-server:
image: seataio/seata-server
hostname: seata-server
ports:
- "8091:8091"
- "7091:7091"
environment:
# 存储模式 用来存储全局事务、全局锁等数据 这里设置为db,可选的方式有file、db、redis
- STORE_MODE=db
- SEATA_PORT=8091
volumes:
- "/usr/share/zoneinfo/Asia/Shanghai:/etc/localtime" #设置系统时区
- "/usr/share/zoneinfo/Asia/Shanghai:/etc/timezone" #设置时区
# 这个文件夹中的信息是seata项目本身的,由于这里使用的是docker容器方式
# 所以可以先启动一个seata容器,利用docker cp 命令将这个文件夹拷贝出来再映射好后重新启动
- "./resources:/seata-server/resources"

application.yml

从容器中cp出resources目录后,在其下面有application.ymlapplication.example.yml两个文件,其中第二个是示例,包括了所有的配置项,第一个是实际运行的配置文件,application.yml

建表

由于这里采用的是db模式,db目前支持mysql、oracle、postgresql,所以需要初始化数据库,数据库名称叫做:seata-server,当然也可以自定义,不过上面的配置就要对应调整,这里采用mysql,mysql建表语句如下,其余的类型详见官方 [建表脚本]

启动

至此stata-server端基本配置完成,在docker-compose.yaml同级目录执行docker-compose up -d启动程序,无错误日志则表示成功。
