linux重启守护进程kill -HUP pid

linux重启守护进程可以使用-HUP参数来发送hang up挂断信号，系统会重启进程进行复位操作重新读取配置文件

kill

pid 是进程标识。如果想要更改配置而不需停止并重新启动服务，请使用该命令。在对配置文件作必要的更改后，发出该命令以动态更新服务配置。

根据约定，当您发送一个挂起信号（信号 1 或 HUP）时，大多数服务器进程（所有常用的进程）都会进行复位操作并重新加载它们的配置文件。

There are also different signals that can be sent to both kill commands. What signal you send will be determined by what results you want from the kill command. For instance, you can send the HUP (hang up) signal to the kill command, which will effectively restart the process. This is always a wise choice when you need the process to immediately restart (such as in the case of a daemon). You can get a list of all the signals that can be sent to the kill command by issuing kill -l. You’ll find

注：自己编写服务无法使用kill -HUP
