我有一个 java 文件，我正在尝试将其安装为服务。但我收到错误。以下是我的文件的内容和错误。我正在运行 Debian 8。

答案1
安装到systemd/system带有.service文件扩展名的；不需要设置可执行位。不要将 systemd 格式的服务文件安装到/etc/init.d/;这适用于旧版 SysVinit 风格的服务脚本。
要启动服务，请使用systemctl start myapp1.当您不确定服务是作为 systemd 还是 SysV 实现时，请使用service myapp1 start。
要在启动时启用[给定适当的Install部分]，请使用systemctl enable myapp1.
