Apache HTTP Server Log

The Apache HTTP Server provides a detailed and flexible information-logging mechanism. The

two most important log files are the error and access logs. The default location for the Apache

HTTP Server log files is the /var/log/httpd directory.

Using the Error Log to Diagnose the Apache HTTP Server

The Apache HTTP Server records diagnostic information and all errors encountered while

processing requests to error_log file.

For example, if you visit a nonexistent URL, the following 404 error is generated:

The requested URL /non-exist/ was not found on this server.

All error information is recorded in the default error log file, which you can obtain by entering

the following command:

# tail –f /var/log/httpd/error_log

The following message is added to the end of the file:

< Fri Jul 18 11:28:41 2008 > <error> <client 10.100.0.22> File does not exist:/var/www/html/non-exist
