我正在 Raspbian 中创建一个非交互式信息亭。我把我不想要的所有东西都删掉了——桌面管理器、各种图形服务等——脚本以 X 开头，一个绝对最小的桌面管理器和 Chromium，加上十几行对抗各种屏幕消隐功能的行，以及另外十几行或更多阻止 Chromium 的行。来自各种弹出窗口的垃圾邮件。
我也为 systemd 创建了单元文件。
从命令行启动时它工作正常。从 开始它工作得很好systemctl start chromium.service。但在我的一生中，我无法让它在启动时自动启动。
首先，单元文件/etc/systemd/system/chromium.service：
[Unit]
Description=Start X and Chromium in kiosk mode
After=getty.target
[Service]
Type=idle
User=pi
ExecStart=/home/pi/start-chromium
[Install]
WantedBy=graphical.target
图形目标是默认的：
root@raspberrypi:/home/pi# ls -l /etc/systemd/system/default.target
lrwxrwxrwx 1 root root 36 lut 24 17:00 /etc/systemd/system/default.target -> /lib/systemd/system/graphical.target
已经激活了：
root@raspberrypi:/home/pi# ls -l /etc/systemd/system/graphical.target.wants/
lrwxrwxrwx 1 root root 36 lut 24 16:28 chromium.service -> /etc/systemd/system/chromium.service
启动消息显示已达到图形目标；自定义服务应介于 getty 和graphical.target 之间：
[ OK ] Started Terminate Plymouth Boot Screen.
Starting Getty on tty1...
[ OK ] Started Getty on tty1.
Starting Serial Getty on ttyAMA0...

但自定义服务不会出现在日志中的任何位置。

答案1
我会增加日志记录的详细程度以获取更多信息。然后在日志文件中 grep 查找 chromium 并向我们展示适当的片段。
为了增加详细程度，在/etc/systemd/system.conf
LogLevel=debug <--- Uncomment this line and use "debug" (default: commented and "info")
我怀疑你的After=线路不正确？您当前的配置显示 chromium 在 getty 之后启动，但首先通过图形系统启用（读取安装）。
你希望 chromium 在图形系统启动后启动（事实上 chromium 会要求图形系统，所以我建议 在行Requires=后添加After=) 并且目标不应该 getty.target是graphical.target和After=行Requires=。
希望增加日志的详细程度能够揭示这一点。我没有尝试过您正在尝试的操作，因此这纯粹是基于我对手册的解释的理论建议。
结语，似乎Install=可以工作，因为当您手动启动时（图形系统启动后），您说它工作正常。
答案2
将自定义服务创建为脚本
打开文件/etc/rc.d/rc.local
在文件行的末尾指向脚本文件位置，例如 sh /{文件路径}/{文件名}.sh
记住 /etc/rc.d/rc.local 和 /{path to file}/{filename}.sh 应该具有可执行权限
注意：Linux系统使用/etc/rc.d/rc.local来运行最后一刻的自定义脚本
