我有一個帶有 Motion v 4.0 的網頁伺服器，但 Motion 不會在啟動時啟動，我必須告訴它每次啟動，然後sudo motion -b一切都很酷，直到我需要重新啟動。我嘗試過編輯配置文件，/etc/motion/motion.conf並且 /etc/defualt/motion
包含變數：start_motion_daemon=yes
哪個應該在啟動時啟動進程？
但當我去檢查時，該進程從未運行。我嘗試設定 rc.local，但 ubuntu 似乎不再這樣做了？
我嘗試使用 systemctl 啟用該服務：
sudo systemctl enable motion
motion.service is not a native service, redirecting to systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable motion
但該服務永遠不會啟用，甚至不會開啟。然後我查看了日誌：

閱讀日誌，我認為該進程正在運行，但事實並非如此。
根據建議，我嘗試設定一個 cron 作業，運行sudo crontab -e
並添加行 @reboot/usr/bin/motion -b
但重新啟動後，運動守護程式仍未運作。
我只想知道在啟動時啟動此過程的現代方法。 Ubuntu 18.04，LXDE。
答案1
你可以使用 cron @reboot
sudo crontab -e
並添加行
@reboot /path/to/bin/motion -b
答案2
首先，嘗試使用 手動運行它sudo -u motion motion。如果有效，則問題是由 systemd 引起的。
這是違反直覺的，但對於 systemd，您應該daemon off在motion.conf 中進行設定。
PS：/etc/defualt/motionUbuntu/Debian 中可能不需要該檔案。
