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
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 quite a large number of signals>

指定进程ID 1011：
kill -HUP 1011
使用/var/run查看进程的ID，操作指定进程
kill -HUP `cat /var/run/nginx.pid`
