Ich habe ein systemd-unit
auf meinem System, das aktiviert ist. Das Problem ist, dass es nach einem Neustart nicht neu startet. Es hängt von zwei anderen Diensten ab, die beide wie erwartet gestartet werden.
Der Dienst ist bekannt, aktiviert und tot:
[centos@ansible-kube-4 ~]$ sudo systemctl status flanneld
flanneld.service - Flanneld overlay address etcd agent
Loaded: loaded (/usr/lib/systemd/system/flanneld.service; enabled)
Active: inactive (dead)
Die Unit-Datei:
[centos@ansible-kube-4 ~]$ cat /usr/lib/systemd/system/flanneld.service
[Unit]

habe ich etwas korrigiert, was ich nicht getan oder verpfuscht hatte und konnte es nicht sehen, weil ich nicht fest genug geblickt habe. Wie auch immer, von zwei identischen Hosts, auf denen ich meinen Dienst nach dem Neustart starten wollte, funktionierte einer und der andere erst, nachdem ich dies getan hatte.
