我有一个python守护程序，希望将日志写入/ var / log / xxxxx / yyyy
该守护程序从start-stop-daemon启动，并为非特权用户提供chuid选项。
但是，当我启动程序时，它将崩溃，并在写入日志文件时出现权限错误。即使我将目录的权限设置为777，也会发生这种情况。
我已为非特权用户授予了适当的权限。我已经通过su向用户检查并在日志目录中写入了一个文件。这样就可以了。 此外，我检查了运行该程序的实际上是正确的用户。这也可以正确签出。 我还检查了start-stop-daemon是否存在问题，因此我从用户tm7手动启动了该程序。这带来了同样的问题。 最后，如果以root身份启动，程序将运行。

我会回答我自己的问题。
好读书是一种被低估的美德…… 它会尝试写入/ var / log / collector，而我的全部精力都放在了/ var / log / tm7 / collector。
希望您在这个无用的问题上不会浪费太多时间...
