Cannot Start Apache

I have this VPS that has been running all this while without a problem. Suddenly, httpd stops. And now when I try to start it, it simply fails.

# service httpd start
Starting httpd:                                            [FAILED]

That's all I get.

I look inside '/etc/httpd/logs/error_log' and this is all there is

...
[Wed Dec 17 14:37:35 2014] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)

Where can I get more information about what may be the problem?

Hi,

What operating system are you using? Did you recently install any custom software? Are you subscribed to any non-standard repositories?

CentOS 6 32bit

No, no custom software installed recently.

Only other repository I have added is EPEL.

As far as I remember, nothing on this VPS was changed in the last 24 hours. Suddenly I got an email from a remote Webmin's Server Status module that this server's web site was "down."

I logged in via SSH. Found a httpd process using 100% of the CPU. I reboot, and when the server comes online, httpd will not start.

Since this is a VPS, can the host server be a cause?

Are you using SSL or have a SSL Apache module enabled?

Yes, I am using SSL and the module is enabled.

Hi,

What type of VPS are you using, OpenVZ, KVM/Xen-based, or other?

Did you by chance recently install an SSL certificate?

If so, take a peek at the Apache error logs contained within the domain where SSL was installed... those are located in $HOME/logs/error_log.

Thank you, Eric, that was exactly it!

I am so embarrassed to admit that I had set up a new certificate and completely forgot about it less than 24 hours later.
