我是一名 Ubuntu 新手，正在关注本教程启用风扇管理mbpfan在运行 Ubuntu 18.04 的 Mac Mini 4.1 上。
一开始我成功了，然后开始尝试将 mbpfan 变成系统服务。我遇到的第一个问题是安装后我的系统上没有 mbpfan.service 文件，所以我就下载了它来自 GitHub，通过 SFTP 将其上传到我的下载文件夹，然后按照 的指示进行复制sudo cp mbpfan.service /etc/systemd/system/。
但是当我尝试执行时，结果如下sudo systemctl enable mbpfan.service：
Synchronizing state of mbpfan.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable mbpfan
Failed to enable unit: File mbpfan.service: Invalid argument
我目前有点困惑，希望您能帮我一下。谢谢。

答案1
您可以按照如下所述创建自定义服务。
但是，您需要知道mbpfan系统上可执行文件的确切路径。为此，请在终端中运行以下命令：
which mbpfan
你将获得如下输出：
/usr/sbin/mbpfan
复制输出并将PATH_TO_MBPFAN其替换到下面的服务文件中。然后，请按照以下说明进行操作。
首先，mbpfan通过在终端中运行以下命令来创建和编辑自定义 systemd 服务：
sudo nano /etc/systemd/system/mbpfancs.service
第二，复制并粘贴以下代码到编辑器中替换PATH_TO_MBPFAN输出并按+然后按 然后按which mbpfan保存文件：CtrlXYEnter
[Unit]
Description=mbpfan Custom Service
[Service]
Type=oneshot
ExecStart=PATH_TO_MBPFAN -f
[Install]
WantedBy=multi-user.target
第三，通过在终端中运行以下命令来启动服务：
sudo systemctl start mbpfancs
第四，通过在终端中运行以下命令来启用该服务：
sudo systemctl enable mbpfancs
最后，重新启动系统。
