Answer 1

你直接kill -9 PID杀了父进程，它的子进程成了孤儿进程。。
你找到父进程，kill就行了，不用-9

比如：

root      6024  5724  0 13:06 pts/0    00:00:00 php Server.php
root      6025  6024  0 13:06 pts/0    00:00:00 php Server.php
root      6028  6025  0 13:06 pts/0    00:00:00 php Server.php
root      6029  6025  0 13:06 pts/0    00:00:00 php Server.php
root      6030  6025  0 13:06 pts/0    00:00:00 php Server.php
root      6031  6025  0 13:06 pts/0    00:00:00 php Server.php
root      6032  6025  0 13:06 pts/0    00:00:00 php Server.php
root      6033  6025  0 13:06 pts/0    00:00:00 php Server.php
root      6034  6025  0 13:06 pts/0    00:00:00 php Server.php
root      6035  6025  0 13:06 pts/0    00:00:00 php Server.php

杀的话就kill 6024
