我试图在 中启动一个脚本/etc/init.d。ubuntu 16.04但它给出了一个错误。我可以手动执行该 (scheduler_slave) 单元中的每个步骤。然而，它在执行脚本时失败了。
有人能解释一下以下错误的含义吗/
我是这个领域的新手，正在尝试弄清楚为什么会出现此错误。如果我遗漏了任何细节，请告诉我。
命令：
sudo /etc/init.d/scheduler_slave start
错误：
[....] Starting scheduler_slave (via systemctl):
scheduler_slave.serviceJob for scheduler_slave.service failed because
the control process exited with error code. See "systemctl status
scheduler_slave.service" and "journalctl -xe" for details.

答案1
您粘贴的错误是“Exec 格式错误”。
已经有一个“Exec 格式错误”的可能原因数Stack Exchange 网络中有记录。我建议查看该答案。
此外，如果可以的话，请避免将 systemd 配置文件与 /etc/init.d 中的旧版“sysVinit”scrypts 混合使用。它们可以协同工作，但会使问题更难调试。我建议systemd尽可能单独使用。
