背景

由于Seata需要配置的项比较多，且YAML文件格式比较矫情，虽然提供了保姆级的安装教程，实施部署过程中仍然遇到各种问题导致Seata安装失败来求助。提供个交互式的Shell脚本，一劳永逸自动部署。
手动部署见：【Seata】seata-server-1.5.1-直接部署（整合nacos）

环境说明

操作系统 Centos7.9
seata版本为 seata-1.5.1
数据库 MySQL5.7
Nacos-2.0.4
离线安装，因部分生产环境不能访问互联网，所以脚本直接做成离线版

下载包目录及使用说明

目录	说明

使用

需要提前手动创建seata的数据库。可以执行扩展增加 MySQL中 seata库自动创建逻辑，考虑部署机器（Seata所在服务器）不一定安装有mysql-client，本文去掉了该部分内容
脚本和离线包上传，保证 seata-install.sh 和 packages 在同一级目录（相对路径不变），shell脚本中使用的相对路径
给shell脚本副执行权限： chmod +x seata-install.sh
执行安装./seata-install.sh
除开始提示是否继续执行，为防止误操作必须手动输入y 外，可以一直使用默认值部署
安装信息输出在seata-install.sh同级的install-info.txt
