I would restart Apache2 but there comes an Error
$ sudo service apache2 start
Starting web server apache2
Action 'start' failed.
The Apache error log may have more information.
But all error logs in "/var/log/apache2/" are empty.
Edit: The Files are at "/var/log/apache2" and there are several entries from previous Problems but this Task doesn't create any new etry ...
Where is the Problem?
It was a error in the SSL Certificate and the path to the "error.log" are changed in the vHost configuration.
If you don't need SSL (i don't because i'm running a local system) simply disable all vHost HTTPS/SSL entrys in the configuration by command line for line out.
Thanks, Tim! Big stumper for me. A few other details others may find helpful:
(Apache2 on Ubuntu 12.04)
I have two sites running on the same server and had just updated the SSL cert for one of them. Upon restarting the server, I got that cryptic message and neither site worked (obviously). I too found the redirect for the log files in the config files. I tracked that down and found the issue (in the log file for the site I had just updated).
My config files are located in /etc/apache2/sites-available
vim or cat the file (cat {filename}) and look for the ErrorLog line. That tells you where to look on your server. cat that file and the error message I found was:
[error] Unable to configure RSA server private key
[error] SSL Library Error: 185073780 error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch
[warn] RSA server certificate CommonName (CN) `<snip>.com' does NOT match server name!?
I had copied one of my cert files to the wrong directory. I simply moved it to the correct directory and everything was fine on the next start. (tip: where those file should be is also in the config file ;)
