屏幕需要带有 systemd 服务的模式 777

Question

我正在尝试将 Minecraft 设置为在启动时在屏幕会话中运行。但通过以下服务文件，以下是我的服务状态。

我是使用 Systemd 引导服务方式的新手，因此任何帮助将不胜感激。

这是我的服务文件

Answer 1

该目录需要具有读、写和执行的完全权限。

你可以执行这个命令chmod -R 777 /var/run/screen

这将递归地将所有文件夹/文件权限更改为 777，尽管通常不太安全。

你也可以运行sudo chown -R $USER:$USER /var/run/screen

这将允许典型的用户/或组完全访问，并且更加安全。
