favorite 20 Does anyone know where file access logs are stored, so I can run a tail -f command in order to see who is accessing a particular file. I have XAMPP, which is an Apache server installed on my machine, which automatically logs the accesses. It is stored in my installation folder. files logs syslog share|improve this question edited May 19 '12 at 12:50 Gilles 368k666671117 asked May 18 '12 at 21:51 AkshaiShah 9912108 On what distribution, or with apache logs location what hosting provider? 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| Did you find this question interesting?

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 Oct 2 '15 at 19:27 add a comment| up vote 5 down vote Apache server records

Apache Log File Format
Virtual Hosts Other Log Files PID File Script Log Rewrite Log Security Warning Anyone who can apache access logs write to the directory where Apache is writing a log file can almost certainly gain access to the uid that the server is started as, apache error log format which is normally root. Do NOT give people write access to the directory the logs are stored in without being aware of the consequences; see the security tips document for details. In addition, log files may contain information supplied directly http://unix.stackexchange.com/questions/38978/where-are-apache-file-access-logs-stored 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 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 https://httpd.apache.org/docs/1.3/logs.html 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 generated the error. Beyond that is the message itself, which in this case indicates that the server has been configured to deny the client access. The server reports the file-system path (as opposed to the web path) of the requested document. A very wide variety of different messages can appear in the error log. Most look similar to the example above. The error log wi
a comment Question: I am trying to troubleshoot Apache web server errors on my http://ask.xmodulo.com/apache-error-log-location-linux.html Linux system. Where is the Apache error log file located on [insert your Linux distro]? Error log and access log files are a useful piece of information for https://www.liquidweb.com/kb/how-to-watch-server-logs-in-real-time/ system admins, for example to troubleshoot their web server, protect it from various malicious activities, or just to run various analytics for HTTP server monitoring. Depending on your error log web server setup, its error/access logs may be found in different places on your system. This post may help you find Apache error log location on Linux. Apache Error Log Location on Debian, Ubuntu or Linux Mint Default Error Log On Debian-based Linux, the system-wide default location of Apache error log is /var/log/apache2/error.log. The default location apache error log can be customized by editing Apache configuration file. Custom Error Log To find a custom error log location, open /etc/apache2/apache2.conf with a text editor, and look for a line that starts with ErrorLog. This line specifies a custom location of Apache error log file. For example, the unmodified Apache configuration file has the following line: ErrorLog ${APACHE_LOG_DIR}/error.log In this case, the location is configured using APACHE_LOG_DIR environment variable, which is defined in /etc/apache2/envvars. export APACHE_LOG_DIR=/var/log/apache2$SUFFIX In reality, ErrorLog may point to any arbitrary path on your Linux system. Custom Error Log with VirtualHost If VirtualHost is used in Apache web server, ErrorLog directive can be specified within VirtualHost container, in which case the system-wide error log location described above will be ignored. With VirtualHost enabled, each VirtualHost can define its own custom error log location. To find out the error log location of a particular VirtualHost, you can open /etc/apache2/sites-enabled/

While going back and reading logs later to determine what happened in the past is helpful, it is also useful to watch logs in real time. Linux provides a command line tool that lets us do just that: tail. A Brief Introduction to Tail The primary purpose of tail is to grab the last few lines of a file (ten lines by default). To do so with any file would look like this: tail example.txt Tail also gives us a way to watch files that are updated by other programs in real time: the -f flag. tail -f example.log While the -f flag is not exclusively for log files, it is the most common use case. When you are through following the log, you will need to press the Control and c keys at the same time in order to stop the tail process. Good Times to Tail: Apache Suppose there is a link on your site that, every time you click on it, gives you an Apache error. Depending on how your site is coded, the error page may not provide you with much information beyond the fact that there is an error message. First, start tailing the error log (n.b.: the following examples assume you have a cPanel server): tail -f /usr/local/apache/logs/error_log If the log is not updating frequently, it is a good idea to hit the spacebar a few times so the error you are trying to reproduce is set apart from previous errors. Then, go back to your browser and click on the link that was giving you the error. It should provide an entry in the error log that matches what you have seen in the browser. This is a surefire way to verify that the log entry corresponds to clicking on that particular link on the site. Good Times to Tail: Exim Another use for tail -f can just be to get a broad overview to see if something is wrong. Often, if you see the same error repeated over and over again in a log file, you can get an indication of a server-wide problem. Perhaps you are starting to hear multiple complaints that email addresses over several domains on your cPanel server are not receiving mail. A quick tail -f /var/log/exim_mainlog could show you in real time that multiple email accounts are all receiving the same error.
