一、环境说明

IP	操作系统	程序	备注
10.0.61.22	centos7.9	PostgreSQL-14.11	已提前部署
10.0.61.21	centos7.9	Nacos-2.1.0	已提前部署
10.0.61.22	centos7.9	seata-server-1.5.1	本文将要部署

二、部署

1. 下载

wget https://github.com/seata/seata/releases/download/v1.5.1/seata-server-1.5.1.tar.gz

2. 解压

tar -zxvf seata-server-1.5.1.tar.gz
# 解压出的文件名 seata，改个名，标注版本
mv seata seata-1.5.1

3. 配置

3.1 application.yml 配置

cd  seata-1.5.1
# 备份
cp seata-1.5.1/conf/application.yml  seata-1.5.1/conf/application.yml.bak
# 修改
vim seata-1.5.1/conf/application.yml

内容如下，具体配置参照 application.example.yml 中配置修改

server:
  port: 8891

spring:
  application:
    name: seata-server

logging:
  config: classpath:logback-spring.xml
  file:
    path: ./logs/seata

console:
  user:
    username: seata
    password: seata

seata:
  config:
    type: nacos
    nacos:
      server-addr: 10.0.61.21:8848
      group: SEATA_GROUP
      namespace: b1b4b131-0fa9-47cf-8ddb-afe1a4c3e7e2
      username: xxxx
      password: xxxx
  registry:
    type: nacos
    nacos:
      application: seata-server
      server-addr: 10.0.61.21:8848
      group: SEATA_GROUP
      namespace: b1b4b131-0fa9-47cf-8ddb-afe1a4c3e7e2
      cluster: default
      username: xxxx
      password: xxxx
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

3.2 seataServer.properties配置

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/v1.5.1/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

注：在部署过程中遇到一个问题导致Seata无法启动，要注意Seata Server端需要配置环境变量在/etc/profile中：
