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 91 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 368k666671117 +1 for CustomLog –Radu 7 hours ago 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

From : http://www.cyberciti.biz/faq/apache-logs/ There are two type of apache httpd server log files: Error Logs All apache errors / diagnostic information other http://unix.stackexchange.com/questions/38978/where-are-apache-file-access-logs-stored errors found while serving requests are logged to this file. Location of error log is set using ErrorLog directive. If there is any problem, you should first take a look at this file using cat, grep or any other UNIX / Linux text utilities. This apache log file often contain details of what went wrong and how to fix it. Default error log file location: RHEL http://blog.codeasite.com/how-do-i-find-apache-http-server-log-files / Red Hat / CentOS / Fedora Linux Apache error file location - /var/log/httpd/error_log Debian / Ubuntu Linux Apache error log file location - /var/log/apache2/error.log FreeBSD Apache error log file location - /var/log/httpd-error.log To find exact apache log file location, you can use grep command:# grep ErrorLog /usr/local/etc/apache22/httpd.conf
# grep ErrorLog /etc/apache2/apache2.conf
# grep ErrorLog /etc/httpd/conf/httpd.conf Sample output: # ErrorLog: The location of the error log file.# If you do not specify an ErrorLog directive within a ErrorLog "/var/log/httpd-error.log" Access Logs Apache server records all incoming requests and all requests processed to a log file. The format of the access log is highly configurable. The location and content of the access log are controlled by the CustomLog directive.

flexible logging capabilities. This document describes how to configure its logging capabilities, and how to understand what the logs contain. Security Warning Error Log Access Log Common Log Format Combined Log https://httpd.apache.org/docs/1.3/logs.html Format Multiple Access Logs Conditional Logging Log Rotation Piped Logs Virtual Hosts Other Log Files PID File Script Log Rewrite Log Security Warning Anyone who can write to the directory where Apache is writing a http://www.apacheviewer.com/log-files/ log file can almost certainly gain access to the uid that the server is started as, which is normally root. Do NOT give people write access to the directory the logs are stored in without error log being aware of the consequences; see the security tips document for details. In addition, log files may contain information supplied directly by the client, without escaping. Therefore, it is possible for malicious clients to insert control-characters in the log files, so care must be taken in dealing with raw logs. Error Log Related Directives ErrorLog LogLevel The server error log, whose name and location is set by the ErrorLog directive, is apache error log 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 second entry lists the severity of the error being reported. The LogLevel directive is used to control the types of errors that are sent to the error log by restricting the severity level. The third entry gives the IP address of the client that generate
logging formats are the NCSA (Common or Combined) used mostly by Apache and the W3C standard used by IIS. These formats will be explain in more detail below. APACHE LOG FILES One of the many pieces of the Website puzzle is Web logs. Traffic analysis is central to most Websites, and the key to getting the most out of your traffic analysis revolves around how you configure your Web logs. Apache is one of the most, if not the most powerful open source solutions for Website operations. You will find that Apache's Web logging features are flexible for the single Website or for managing numerous domains requiring Web log analysis. For the single site, Apache is pretty much configured for logging in the default install. The initial httpd.conf file (found in /etc/httpd/conf/httpd.conf in most cases) should have a section on logs that looks similar to this (Apache 2.0.x), with descriptive comments for each item. Your default logs folder will be found in /etc/httpd/logs . This location can be changed when dealing with multiple Websites, as we'll see later. For now, let's review this section of log configuration. ErrorLog logs/error_log LogLevel warn LogFormat "%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i"" combined LogFormat "%h %l %u %t "%r" %>s %b" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent CustomLog logs/access_log combined Error Logs The error log contains messages sent from Apache for errors encountered during the course of operation. This log is very useful for troubleshooting Apache issues on the server side. Apache Log Tip: If you are monitoring errors or testing your server, you can use the command line to interactively watch log entries. Open a shell session and type "tail ?f /path/to/error_log" . This will show you the last few entries in the file and also continue to show new entries as they occur. There are no real customization options available, other than telling Apache where to establish the file, and what level of error logging you seek to capture. First, let's look at the error log configuration code from httpd.conf. E
