我是做服务器配置的新手，这些是我采取的步骤，但是在 Tomcat 10 中运行的 Web 应用程序不起作用。
这是我的项目结构：
- 将 MySQL 安装到 Droplet
- 将Tomcat安装到Droplet
- 将 MySQL 连接器 .JAR 文件放入 /tomcat/lib 文件夹
- 启用 SSL 连接到 4334 端口
- 将 Github 存储库克隆到 /webapps 文件夹中
- 在 /conf 中的 context.xml 中添加了数据库连接器，并在服务器文件夹中创建了 META-INF/context.xml 文件夹。
Tomcat 运行没有错误。但是服务器不工作。它在 Windows 中完美运行。这是一个客户发送订单并提供邮件服务的项目。
也许在将项目上传到服务器之前，我必须在项目内部做一些事情？我尝试使用 .war 文件，但没有成功。日志：
