Systemd，无法启动 dcos-link-env.service

以下是systemctl status dcos-link-env.service

 ● dcos-link-env.service

更新 1：我按照“Mark Stosberg”提供的解决方案操作，并解决了他提到的问题。但是出现了一个有点模糊的新错误（至少对我来说）。以下是错误。

systemctl status dcos-link-env
● dcos-link-env.service

答案1

看看这一行：

>  ExecStartPre=/usr/bin/mkdir -p /etc/profile.d (code=exited, status=203/EXEC)

因此，此命令以失败代码退出。您是否以 root 身份在 CLI 上运行了该命令以确认其按预期运行？

在 Ubuntu 16.04 上，which mkdir显示该二进制文件位于/bin/mkdir，而不是/usr/bin/mkdir您所拥有的。
