Supervisord立即发送SIGKILL

Question

我正在使用launchd启动supervisord，而supervisord又启动一个小的python文件，这是一个连接到reddit的机器人。

每当supervisord使用此方法启动时，它会立即发送SIGKILL。当我手动启动supervisord时，此过程启动正常，并将一直工作，直到手动退出。

Answer 1

最有可能（这是猜测，因为你没有在问题中包含你的launchd配置），你没有将-n参数传递给supervisor以防止你的launchd配置中的自我守护。

当程序的主PID退出时，launchd会考虑与孤儿相关的剩余进程，并清除它们。

为了避免这种情况，永远不要将在监督系统下运行的软件配置为自我守护，除非该监督系统明确支持以下子节点并且配置为这样做。
