查找觸發重啟的程序或程序
每天晚上凌晨 3:00，我的 Raspberry 會重新啟動，但我所做的或正在執行的任何事情都沒有觸發這個。我想確定“違規”程序並禁用重新啟動。
這是目前版本：
pi@raspberrypi:~ $ lsb_release -a No LSB modules are available. Distributor ID: Raspbian Description: Raspbian GNU/Linux 10 (buster) Release: 10 Codename: buster我檢查了
crontab -e；沒有什麼會觸發這個。關於如何辨識可能觸發計劃重啟的其他建議？謝謝你。

systemd-tmpfiles-clean.service凌晨 3 點 15 分執行的那個，但恰好在凌晨 3 點 00 分，系統重新啟動。不過，我是 systemd 的新手，所以也許還有其他沒有透露的計時器？我試過
sudo systemctl list-timers --all了，但得到了相同的列表。我還在 cron.daily 中找到了以下內容；在審查了每個腳本之後，沒有什麼會觸發重新啟動（儘管如果我正確解釋了 /etc/crontab，那麼每日腳本無論如何都會在第 6 分鐘（但不清楚幾點）執行，而不是在小時。
pi@raspberrypi:~ $ cat /etc/crontab # /etc/crontab: system-wide crontab # Unlike any other crontab you don't have to run the `crontab' # command to install the new version when you edit this file # and files in /etc/cron.d.

好消息是對命令的修改記錄了請求 - 請參見最後兩行：
pi@raspberrypi:~/splitflap $ cat /var/log/user.log <4 other lines removed> May 8 03:00:01 raspberrypi reboot: Reboot requested but ignored: reboot May 8 03:00:01 raspberrypi reboot: Parent: root 15328 15318 0 03:00 ? 00:00:00 /bin/sh -c /sbin/rebootDef 感覺更近了，但我在這裡承認我缺乏關於如何進一步辨識有問題的程序或服務的知識 - 當我執行
ps -ef.
如果您替換
/sbin/reboot為通知和日誌記錄腳本，它可能有助於確定導致重新啟動的原因。這是設置此類腳本的一個範例：mv /sbin/reboot /sbin/reboot.REAL cat >>/sbin/reboot <'x' #!/bin/bash # logger -t reboot "Reboot requested but ignored: reboot $*" # Identify the calling process ps=$(ps -ef | awk -v ppid=$PPID '$2 == ppid') logger -t reboot "Parent: $ps" # Abort exit 1 x chmod a+x /sbin/reboot當您將此稱為假時，您將在每次呼叫
reboot中獲得兩個條目。/var/log/user.log例如，May 7 16:06:20 pi reboot: Reboot requested but ignored May 7 16:06:20 pi reboot: Parent: roaima 20862 20857 0 16:01 pts/0 00:00:00 -bash可能需要對
systemctl ... reboot. 這有點困難，因為不破壞其他功能很重要。像這樣開始的腳本可能適合安裝為/bin/systemctl：#!/bin/bash # if [[ "$*" != *reboot* ]] then logger -t reboot "Not a reboot: systemctl $*" exec /bin/systemctl.REAL "$@" fi logger -t reboot "Reboot requested but ignored: systemctl $*" ...
