if you have pid of the processes that want to kill then use killcommand.
如果您有要杀死的进程的 pid，则使用kill命令。
kill pid1 [pid2 pid3 ...]
And if this doesn't kill the processes you can add -9flag to killcommand to forcefully kill the processes like
如果这不会杀死进程，您可以-9向kill命令添加标志以强行杀死进程，例如
kill -9 pid1 [pid2 pid3 ...]
To get the pid of the process you can use pscommand as
要获取进程的 pid，您可以使用ps命令作为
ps ax | grep apache
first column of output is the pid of the process.
输出的第一列是进程的pid。

Try the following:
请尝试以下操作：
killall apache2
if you want to kill all apache processes.
如果你想杀死所有的 apache 进程。
ps aux | grep apache2
will show the apache servers with their PID. Then you can kill selectively:
将显示带有 PID 的 apache 服务器。然后你可以有选择地杀死：
kill -9 pid1 pid5

Note the Linux command killall. You can kill processes by name and thus do something a little more coarse-grained than using the pid. You can use names or regular expressions (with the -roption) to specifiy your victims.
请注意 Linux 命令killall。您可以按名称终止进程，从而执行比使用 pid 更粗粒度的操作。您可以使用名称或正则表达式（带有-r选项）来指定您的受害者。
Use a normal SIGTERM(default) to begin with. This will let the processes catch the signal, and if they're well-behaved they'll clear up/close resources properly and then exit. Only if the processes don't respond should you use the SIGKILL(-9) signal.
使用普通SIGTERM（默认）开始。这将使进程捕获信号，如果它们表现良好，它们将正确清除/关闭资源，然后退出。只有当进程没有响应时才应该使用SIGKILL(-9) 信号。
