场景

生产环境都是以集群的方式部署seata, 这里演示下部署方式

环境介绍

1. 2台centos7.9的开发机(内网ip100.64.0.4 ,100.64.0.3)
2. jdk17
3. 一个nacos服务
4. 一个8.0.40版本的mysql服务
5. seata 1.7.1集群部署

seata存储到mysql, 注册到nacos 所以需要做2个配置项的修改;
PS: 如果有需要的话 可以使用nacos替换file配置

100.64.0.3节点部署seata

1. 下载seata 1.7.1安装包

wget https://github.com/seata/seata/releases/download/v1.7.1/seata-server-1.7.1.tar.gz

tar -zxvf seata-server-1.7.1.tar.gz 

2. 初始化seata数据库

初始化sql脚本在 seata/script/server/db/mysql.sql
我新建了seata数据库

3. 将存储切换到mysql

conf/application.yaml

4. 注册到nacos

100.64.0.4节点部署seata

同 100.64.0.3节点

nacos注册的效果

我的配置,可以参考下
