我正在尝试创建一个systemd用户单元,并在系统启动时启动它。该服务会手动启动,但是不会在启动时启动。
通过搜索Internet,我了解到要使用户单元在启动时启动,我应该运行loginctl enable-linger <username>
,但这似乎没有任何作用。实际上,手册页中说:
Enable/disable user lingering for one or more users. If enabled for a specific user, a user manager is spawned for the user at boot and kept around after logouts. This allows users who are not logged in to run long-running services.
尽管运行此命令,但我的服务在启动时无法启动。
loginctl enable-linger error
那个单位:
$ cat ~/.config/systemd/user/thin\@.service
[Unit]
Description=A fast and very simple Ruby web server
[Service]
Type=simple

[Install]
WantedBy=multi-user.target
重新启动后,它没有运行:

我可以手动启动它,并且可以正常工作:
$ systemctl --user start thin@redmine
$ systemctl --user status thin@redmine -l

我如何弄清楚为什么该服务无法在启动时启动,并使其启动?
操作系统是Fedora 23 x86_64,系统版本222-10。
