In addition, log files may contain information supplied directly by the client, without escaping.

This is the place where Apache httpd will send diagnostic information and record any errors that it encounters in processing requests. It is the first place to look when a problem occurs with starting the server or with the operation of the server, since it will often contain details of what went wrong and how to fix it. The error log is usually written to a file (typically error_log on unix systems and error.log on Windows and OS/2). On unix systems it is also possible to have the server send errors to syslog or pipe them to a program. The format of the error log is relatively free-form and descriptive. But there is certain information that is contained in most error log entries. For example, here is a typical message.

I'd like to try to find out why. It looks like it never started up today, so nothing in /var/log/apache2/error.log since it never ran. As I understand it, the apache script is /etc/init.d/apache2 so I'd like to find some messages somewhere regarding this script. However, I can't find anything in /var/log/messages or the syslog. Is there anywhere in the system where it says "Yep, apache error log I'm starting up /etc/init.d/apache2 now; it worked" or especially "It didn't work and here's why!" ? I am using Ubuntu Release 10.04 (lucid), Kernel Linux 2.6.32-38, and GNOME 2.30.2 . 10.04 startup apache2 logging share|improve this question edited Apr 7 '12 at 1:16 david6 11.4k32441 asked Apr 6 '12 at 23:40 Roy 75115 Did you check /var/log/syslog? –Justin Andrusk Apr 7 '12 at 0:36 Yes, that's what I meant when I wrote "syslog" at the end of my first paragraph. –Roy Apr 7 '12 at 3:40 add a comment| 3 Answers 3 active oldest votes up vote 1 down vote accepted You could go to a terminal and type in "sudo /etc/init.d/apache2 restart" in a terminal, and see what kind of error message you get. One common reason, I believe, is because of some module that was either added, changed, or had a change made to a corresponding config file (such as php.ini). If all else fails, go to the directory /etc/apache2/mods-enabled, and move module links out into a temporary directory, and if apache starts, you can put them back one by one. Be aware, though, that the error message may be misleading. It may get an error loading a module not because the module is bad, but because it's configuration file is bad. share|improve this answer answered Apr 7 '12 at 1:42 Marty Fried 9,772327
