我最近将虚拟机从 utopic 更新到了 Vivid 15.04。我以前有一个用于 uwsgi 的 init.d 脚本，现在它不再起作用了。
我按照官方文档从这里使用 SystemD 创建了一个 uwsgi 服务守护进程：http://uwsgi-docs.readthedocs.org/en/latest/Systemd.html。
这看起来很简单，但是当我运行服务时出现这个错误。
miruka@*****:~$ sudo systemctl start emperor.uwsgi.service
Job for emperor.uwsgi.service failed. See "systemctl status emperor.uwsgi.service" and "journalctl -xe" for details.
我不知道为什么。无论如何，此后，systemctl 崩溃并且无法使用。
sudo systemctl start emperor.uwsgi.service
Failed to get D-Bus connection: Operation not permitted
在 dmesg 中我看到：

重新启动可以解决问题，但我仍然无法运行我的服务。有什么想法吗？
答案1
注释掉RuntimeDirectory指令emperor.uwsgi.service对我来说解决了这个问题。我不确定为什么这样可以解决问题，或者这个更改是否会带来任何负面影响。
顺便说一句，通过启用它，emperor.uwsgi.service我能够让它在启动时正常启动，但是停止它会锁定 systemd 并且我不得不强制我的 VM 停止（无法重新启动或停止）然后重新启动它。
