Question

我遇到了一个问题，尽管经过数小时的努力，包括搜索众多的Linux论坛，我仍然无法解决这个问题。我的init.d脚本基于标准脚本来启动python脚本作为服务。我已经将此脚本用于其他服务而没有任何问题，但这次不是。

长话短说，我的问题如下：

如果我在我的主目录中执行它，该脚本可以正常工作。我可以开始和停止服务等。

如果我在/etc/init.d中执行脚本，它也可以正常工作，如果我之前在我的主目录中运行了一次。如果我尝试在重新启动后立即执行脚本，则没有任何反应。因此，重新启动后服务不会启动。使用服务“script_name”start / stop / restart运行脚本遵循相同的模式。好的，如果我先从我的主目录执行脚本，否则没有任何反应。

我觉得它与环境有关，但如果我在从我的主目录执行脚本之前和之后检查printenv，我看不到任何变化。通过从我的主目录运行脚本，我认为没有其他任何事情可以改变。我用sudo运行脚本。

由于脚本与我在另一个Rasp上使用的脚本完全相同，除了Python脚本的名称（并且它在那里工作......），我几乎不相信脚本中有问题。

编辑：我刚注意到我可以注销/开启，这不会影响状态。所以我仍然可以在/etc/init.d中运行它，如果我从上次重启后从我的主目录执行一次就能使它工作。脚本来了：

除非首先从本地目录执行相同的脚本，否则init.d脚本不起作用
