阿帕奇无法启动，但没有显示错误 [英] Apache wont start but shows no errors
本文介绍了阿帕奇无法启动，但没有显示错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我重新启动一个CentOS 6.2虚拟机（运行的Virtualmin），并将其挂在启动时，当它被开始的httpd。从现场CD启动，拆除，从rc3.d.启动Apache的脚本服务器开始，现在我可以SSH到它。一直试图解决：
I rebooted a CentOS 6.2 VM (running Virtualmin) and it hung on startup when it was "starting httpd". Booted from a live CD, removed the script that started apache from rc3.d. Server started, now I can SSH into it. Kept trying to troubleshoot:
> httpd -v
Server version: Apache/2.2.15 (Unix)
Server built: May 16 2012 22:32:26
但我不能启动它。它挂在启动httpd的，因为它在引导过程中做到了。
but I cant start it. it hangs on "starting httpd", as it did during boot up.
> service httpd status
httpd is stopped
我不能连测试的配置，apachectl中configtest只是停留在那里，直到我打CTRL-C。我也试图启动Apache与所有的LoadModule指令注释掉。唯一的模块编译如下：
I cant even test the config, "apachectl configtest" just stays there until I hit CTRL-C. I also tried to start apache with all LoadModule directives commented out. The only compiled in modules are:
> apachectl -l
Compiled in modules:
core.c
prefork.c
http_core.c
mod_so.c
我试图重新加载所有Apache的配置（通过Webmin的备份恢复），仍然没有去。
I tried to reload all apache config (via webmin backup restore) and still no go.
我在几个地方读到，当发生这种情况可能有一些做与SSL证书。我试图用的SSLEngine可以坚持在ssl.conf中。我试图荫重新安装httpd的。
I read in a couple places that when this happens it can have something to do with SSL certs. I tried to run it with SSLEngine off in ssl.conf. I tried "yum reinstall httpd".

请帮帮忙！
推荐答案
原来，引导到不同的内核（默认是的原子能火箭龟ASL ）允许的httpd启动罚款。
It turns out that booting into a different kernel (default was Atomic Rocket Turtle ASL) allowed httpd to start fine.
