Troubleshooting with Apache logging

Filed under
HowTos

The Apache Web server (Apache) comes with a powerful logging framework. In the default configuration, Apache logs all errors to an error log and all access requests to an access log. The default level of logging is sufficient for analyzing traffic patterns and for getting basic information about errors, but it may be inadequate for troubleshooting purposes. Familiarity with all the logging features can help you troubleshoot the Web server or applications hosted on Apache.

In the default installation of Apache on Fedora, you can find the access log at /etc/httpd/logs/access_log and the error log at /etc/httpd/logs/error_log. The access log captures one line of information for each request. The error log captures the date and time of a request, the severity level of an event, the client's IP address, and the description of the error. Error logging is a part of the core functionality of Apache, while other bits in the logging functionality come from modules such as mod_log_config, mod_dumpio, and mod_log_forensic.

You can customize the format of access log by using the configuration directive LogFormat in the configuration file httpd.conf (in /etc/httpd/conf directory on Fedora).

The Licensing and Compliance Lab interviews AJ Jordon of gplenforced.org

So basically Bradley Kuhn gave a talk at FOSDEM '17 about GPL enforcement and I was like, wow, it sucks how many companies and people think that enforcing the GPL is a bad idea. I mean, if you disagree with copyleft that's fine (though I personally would argue with that position), but then you should use a suitable license. Like MIT. The very idea that we shouldn't enforce the GPL just doesn't make sense to me because it suggests that the text of the license is watery and unimportant. I don't know about you, but when I say I want my programs to respect users' freedom, I mean it. So GPL enforcement is important. It seemed to me that there are probably a lot of developers out there who want to support GPL enforcement but don't have a good way to voice that support. gplenforced.org is essentially a quick and dirty hack I wrote to make that dead-simple.
