环境需求

• mysql 5.6+
• redis 3.0+
• 该项目是一个 Eureka Client 项目，启动后需要注册到 EurekaServer，本地环境需要 eureka-server，线上环境需要使用 go-register-server

安装和启动步骤

• 运行 eureka-server，代码库地址。

• 拉取当前项目到本地，执行如下命令：

   git clone https://code.choerodon.com.cn/choerodon-framework/asgard-service.git
  

• 创建数据库，本地创建 asgard_service 数据库和默认用户，示例如下：

  CREATE USER 'choerodon'@'%' IDENTIFIED BY "123456";
  CREATE DATABASE asgard_service DEFAULT CHARACTER SET utf8;
  GRANT ALL PRIVILEGES ON asgard_service.* TO choerodon@'%';
  FLUSH PRIVILEGES;
  

• 初始化 asgard_service 数据库，运行项目根目录下的 init-local-database.sh，该脚本默认初始化数据库的地址为 localhost，若有变更需要修改脚本文件

  sh init-local-database.sh
  

• 本地启动 redis-server

• 启动项目，项目根目录下执行如下命令：

   mvn spring-boot:run
