Ubuntu 部署 Seata1.7.1
一、环境说明
| IP | 操作系统 | 程序 | 备注 |
|---|---|---|---|
| 10.0.61.22 | ubuntu20.04 | PostgreSQL-14.11 | 已提前部署 |
| 10.0.61.21 | ubuntu20.04 | Nacos-2.1.0 | 已提前部署 |
| 10.0.61.22 | ubuntu20.04 | seata-server-1.7.1 | 本文将要部署 |
二、部署
1. 下载
wget https://github.com/seata/seata/releases/download/v1.7.1/seata-server-1.7.1.tar.gz
2. 解压
tar -zxvf seata-server-1.7.1.tar.gz
# 解压出的文件名 seata，改个名，标注版本
mv seata seata-1.7.1
3. 配置
3.1 application.yml 配置
cd seata-1.7.1
# 备份
cp ./conf/application.yml ./conf/application.yml.bak
# 修改
vim ./conf/application.yml
内容如下，具体配置参照 application.example.yml 中配置修改

属性配置官方文档说明（未更新，还是1.4.2版本）：https://seata.io/zh-cn/docs/user/configurations.html
详细配置（由于Github访问限制，给个Gitee仓库的链接）：https://gitee.com/seata-io/seata/blob/v1.7.1/script/config-center/config.txt
- 创建 seataServer.properties ，注意 namespace 、 group 、data-id 和上述 application.yml 配置中心的配置 保持一致，内容参照 详细配置链接 中配置按需配即可
- 事务分组概念： https://seata.io/zh-cn/docs/user/txgroup/transaction-group.html

#seata
export SEATA_IP=192.168.28.128环境变量生效，命令如下：
# source /etc/profile启动 seata-server，命令如下：
# nohup bash ./bin/seata-server.sh start -h 192.168.28.128 -m db &> seata.log &开启以下端口：
