我想每天早上 6:00 重启 vsftpd 服务，但是这个脚本会在早上 6 点到 7 点每分钟重启一次服务。我该怎么办？

这是计时器 vsftpd-restart.timer

[Unit]
Description=Restart vsftpd daily at 6 AM
After=network.target

[Timer]
Unit=vsftpd-restart.service
OnCalendar=*-*-* 06:00:00
Persistent=true

[Install]
WantedBy=timers.target

这是脚本 vsftpd-restart.service

[Unit]
Description=Restart vsftpd daily at 6 AM
After=network.target

[Service]
Type=oneshot
ExecStart=/bin/bash -c 'systemctl stop vsftpd; systemctl start vsftpd'

[Install]
WantedBy=vsftpd-restart.timer

以下是 vsftpd systemctl 日志

    当前设置导致 vsftpd 服务从早上 6:00 到 7:00 每分钟重新启动一次，原因是 OnCalendar= - -* 06:00:00 计时器是持久的 (Persistent=true)。这意味着计时器会尝试在系统关闭期间“追上”错过的事件，因此如果系统在早上 6 点关闭，则系统重新上线时会导致多个触发器。这应该可以做到：

    vsftpd 重启定时器

    [Unit]
Description=Restart vsftpd daily at 6 AM
After=network.target

[Timer]
Unit=vsftpd-restart.service
OnCalendar=*-*-* 06:00:00
AccuracySec=1min  # Optional: Adds a margin to avoid precision issues
Persistent=false  # Ensures it only triggers at the exact time and doesn't catch up on missed triggers

[Install]
WantedBy=timers.target

    并且不要忘记使用新的计时器脚本重新加载：

    sudo systemctl daemon-reload
sudo systemctl restart vsftpd-restart.timer
