I feel its better to kill the process itself, find out the process id and kill it and then do a fresh start, it should work fine
我觉得最好杀死进程本身，找出进程ID并杀死它然后重新开始，它应该可以正常工作

I ran into this problem when I installed apache from source, but then tried to run
当我从源代码安装 apache 时遇到了这个问题，但随后尝试运行
$ sudo /etc/init.d/httpd restart
which was using a pre-installed version of apache. The stop directive in /etc/init.d/httpd was not removing the httpd.pid file that was created when starting the source-installed version of apache.
这是使用预装版本的 apache。/etc/init.d/httpd 中的 stop 指令没有删除在启动源安装版本的 apache 时创建的 httpd.pid 文件。
To determine if this is also the reason for your problem, find where the httpd.pid file is getting set when you run
要确定这是否也是您的问题的原因，请查找运行时设置 httpd.pid 文件的位置
$ sudo apachectl start
If you installed from source and apache2 is living in /usr/local/apache2, then the httpd.pid file should get created in /usr/local/apache2/logs. When you stop apache by running
如果您从源代码安装并且 apache2 位于 /usr/local/apache2，则应该在 /usr/local/apache2/logs 中创建 httpd.pid 文件。当您通过运行停止 apache 时
$ sudo apachectl stop
this file should get removed. So to test if the httpd.pid file is causing your problem, start apache by calling
这个文件应该被删除。因此，要测试 httpd.pid 文件是否导致您的问题，请通过调用启动 apache
$ sudo apachectl start
and locate the httpd.pid file. Then try stopping apache by using
并找到 httpd.pid 文件。然后尝试使用停止 apache
$ sudo /etc/init.d/httpd stop
If the original httpd.pid file is still present, then that is why apache is unable to start when you use
如果原来的httpd.pid文件还在，那就是你使用apache无法启动的原因
$ sudo /etc/init.d/httpd start
To get my /etc/init.d/httpd file to work correctly, I explicitly put the call to apachectl in the start and stop methods:
为了让我的 /etc/init.d/httpd 文件正常工作，我在 start 和 stop 方法中明确地调用了 apachectl：
#!/bin/bash
# /etc/init.d/httpd
#
# Path to the apachectl script, server binary, and short-form for messages.
apachectl=/usr/local/apache2/bin/apachectl
httpd=/usr/local/apache2/bin/httpd
pid=/usr/local/apache2/logs/httpd.pid
prog=httpd
RETVAL=0
start() {
echo -n $"Starting $prog: "
$apachectl -k start
RETVAL=$?
echo
return $RETVAL
}
stop() {
echo -n $"Stopping $prog: "
$apachectl -k stop
RETVAL=$?
echo
}

I tried this and it works:
我试过这个，它有效：
- sudo fuser -k -n tcp 80
- sudo service httpd start
- 须藤热熔器 -k -n tcp 80
- 须藤服务 httpd 启动
Hope this will help you!
希望能帮到你！
Cheers
干杯

I have had this issue very rarely over the last couple years with a server I've been managing. Unfortunately, if you are getting FAILED after trying to restart, the process that's managing the connection on port 80 won't release it's hold on that port.
在过去的几年里，我一直在管理的服务器上很少遇到这个问题。不幸的是，如果您在尝试重新启动后失败，则管理端口 80 上的连接的进程不会释放它对该端口的保持。
I would try a full "sudo /etc/init.d/httpd stop" wait for that to finish or fail.
我会尝试一个完整的“sudo /etc/init.d/httpd stop”等待它完成或失败。
If that doesn't fix it you'll have to restart the server completely. Hopefully, it's configured to start everything up automatically on restart, but that isn't guaranteed.
如果这不能解决它，您将不得不完全重新启动服务器。希望它被配置为在重新启动时自动启动一切，但这并不能保证。
"apachectl" is also great tool for Apache, but it may not be on this server, it depends on the install and linux distro used.
“apachectl”也是 Apache 的好工具，但它可能不在此服务器上，这取决于安装和使用的 linux 发行版。
If after rebooting the server, apache still fails to start, something bad has happened. I'd consider pulling all the website and conf files for creating a new server at that point, but the apache start, and then failed message output should give you some idea of where to look in the Logs about why it cannot start.
如果重新启动服务器后，apache 仍然无法启动，则发生了一些不好的事情。我会考虑在那时拉出所有网站和 conf 文件以创建新服务器，但是 apache 启动，然后失败的消息输出应该让您了解在日志中查看为什么无法启动的原因。
