मैं एक systemd उपयोगकर्ता इकाई बनाने की कोशिश कर रहा हूँ और यह तब शुरू होता है जब सिस्टम बूट होता है। सेवा मैन्युअल रूप से प्रारंभ होती है, हालांकि यह बूट पर शुरू नहीं होती है।
इंटरनेट पर खोज करने से मुझे पता चला कि बूट पर शुरू करने के लिए उपयोगकर्ता इकाइयों के लिए, मुझे माना जाता है कि इसे चलाने की आवश्यकता है loginctl enable-linger <username>
, लेकिन ऐसा लगता है कि इसका कोई प्रभाव नहीं पड़ा। दरअसल, मैन पेज कहता है:
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.
इस आदेश को चलाने के बावजूद, मेरी सेवा बूट पर शुरू नहीं होती है।
loginctl enable-linger error
इकाई:
$ cat ~/.config/systemd/user/thin\@.service
[Unit]
Description=A fast and very simple Ruby web server
[Service]

[Install]

जब मैं रिबूट करता हूं, तो यह नहीं चल रहा है:

मैं यह कैसे पता लगा सकता हूं कि यह सेवा बूट पर क्यों नहीं शुरू होती है, और ऐसा करने के लिए इसे प्राप्त करें?
