Jenkins自动化部署之后端

准备工作参考本人另外几篇Jenkins相关的文章

1. 新建任务
   

2. 添加参数配置
   
   字符串参数：分支名称
   
   
   多选框：项目名称（Extended Choice Parameter插件必备，插件安装参考我另外的文章）

travel-system:8201@travel-modules/,travel-auth:8200,travel-gateway:7070,travel-backend:8204@travel-modules/,travel-ticket:8205@travel-modules/

如果项目存在依赖情况B依赖A,需要先部署A才能部署B，则可以通过调整此处项目顺序

此处如果项目名称没有转换为中文，检查Choose Source for Value Description中描述直接的分割符号是否与前面的相同，假如前面是英文逗号，后面是中文逗号此处也是会有问题

4. 配置代码拉去
   
   应用，报存

5. 配置远程部署服务器

• 拷贝公钥到远程服务器

ssh-copy-id 远程服务器IP

• 系统配置->添加远程服务器
  

6. 参数添加
   多选框：部署服务器
