Logs are typically under /var/log, but some systems have them elsewhere. –Gilles May 19 '12 at 12:51 add a comment| 3 Answers 3 active oldest votes up vote 92 down vote accepted Ultimately, this depends on your Apache configuration. Look for CustomLog directives in your Apache configuration, see the manual for examples. A typical location for all log files is /var/log and subdirectories. Try /var/log/apache/access.log or /var/log/apache2/access.log. If the logs aren't there, try running locate access.log. share|improve this answer answered May 19 '12 at 12:54 Gilles 371k696751126 +1 for CustomLog –Radu Sep 30 at 14:05 add a comment| up vote 20 down vote If you can't find the log with Gilles's answer, there are a couple more things you can try. Look in /var/log/httpd. Run sudo locate access.log as well as sudo locate access_log. The logs on my system were not visible except to root, and the file was called access_log instead of access.log. share|improve this answer answered Jan 27 '15 at 19:28 Don Kirkby 30124 3 +1 for /var/log/httpd - led me right to it on our CentOS installation –Chuck Wilbur O

Error Log Related Directives ErrorLog LogLevel The server error https://httpd.apache.org/docs/1.3/logs.html log, whose name and location is set by the ErrorLog directive, is the most important log file. 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. [Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1] client denied by server configuration: /export/home/live/ap/htdocs/test The first item in the log entry is the date and time of the message.

The main avenue for providing feedback to the administrator is through the use of log files. Apache has a very configurable logging mechanism that can be used to output messages to different places based on instructions. In this guide, we will look at how to utilize Apache's logging functionality to set up structured, easy-to-parse logs. We will be using a default Apache2 installation on an Ubuntu 12.04 VPS. apache error log Other distributions should operate in a similar fashion. Apache Log Levels Apache separates all informational messages into categories depending on how important it considers the information. For instance, for the most important messages, considered emergencies, Apache designates the log level as "emerg". The "info" tag, on the other hand, just shows helpful information that can be useful to look at occasionally. Here are the log levels that Apache recognizes, from most important to least: emerg: Emergency situations where the system is in an unusable state. alert: Severe situation where action is needed promptly. crit: Important problems that need to be addressed. error: An Error has occurred. Something was unsuccessful. warn: Something out of the ordinary happened, but not a cause for concern. notice: Something normal, but worth noting has happened. info: An informational message that might be nice to know. debug: Debugging information that can be useful to pinpoint where a problem is occurring. trace[1-8]: Tracing information of various levels of verbosity that produces a large amount of information. When you specify a log level, you are not choosing to log the messages labeled in that category, you are choosing the least important level that you wish to log. This means that any levels above the selected level are also logged. For example, if you choose
