登录后如何使Linux从Spring Boot启动？

Question

在Linux登录失败之后，我尝试从spring开始启动，有人可以告诉我我做错了什么吗？

我有两个问题..

我可以仅通过调用sudo用户来运行该应用程序，如果没有发生以下错误

向我解释为什么会发生此错误..如何使应用程序在Linux上的用户登录后运行，并指出该登录是在没有sudo权限的情况下自动发生的，那么jar应该以755权限运行吗？

thank you advanced.

Answer 1

应该简单明了。我相信您使用的是端口80，而不是8080：

低于1024的端口是特权端口，因此需要sudo用户

请参阅文件：

http://www.w3.org/Daemon/User/Installation/PrivilegedPorts.html

通过类似于-Dserver.port = 8080的运行VM参数传递服务器端口，或者搜索application.properties并在其中指定server.port = 8080。

以上应该可以正常工作。

希望这可以帮助。
