“service gunicorn restart”中的 Gunicorn 来自哪里？

Question

当我pip freeze，我看不到 Gunicorn。我在想当Gunicorn我跑的时候，它从哪里来service gunicorn restart/stop。它service和什么有关Upstart？

谢谢。

编辑：

我现在明白，在 中service gunicorn restart，只是我放置在 中的gunicorn脚本的名称（不带扩展名） 。是在 中搜索 System-V 脚本和 在 中的 Upstart 脚本的命令。.conf/etc/init/service/etc/init.d/etc/init

有人能帮忙看看这个表是否有问题吗？

现在 systemd 是 Ubuntu 中的初始化系统，该表看起来更像这样：
