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.

Files PID File Script Log Rewrite Log Security Warning Anyone who can write to the directory where Apache is writing a apache log format 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 http://unix.stackexchange.com/questions/38978/where-are-apache-file-access-logs-stored 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 https://httpd.apache.org/docs/1.3/logs.html 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 genera
Error Logs General Configuration Debian/Ubuntu/Linux Mint Configuration Redhat/Fedora/CentOS Configuration OpenSUSE Configuration Applicable Modules ↑ 0 Access and Error Logs Log Files An Apache log is a record of the events that have occurred https://www.loggly.com/ultimate-guide/access-and-error-logs/ on your Apache web server. Apache stores two kinds of logs: Access Log Contains information about requests coming in to the web server. This information can include what pages people are viewing, the success status of requests, and how long the request took to respond. It looks something like this: 10.185.248.71 - - [09/Jan/2015:19:12:06 +0000] 808840 "GET /inventoryService/inventory/purchaseItem?userId=20253471&itemId=23434300 HTTP/1.1" 500 17 "-" "Apache-HttpClient/4.2.6 (java apache log 1.5)" Error Log Contains information about errors that the web server encountered when processing requests, such as when files are missing. It looks something like this: [Thu Mar 13 19:04:13 2014] [error] [client 50.0.134.125] File does not exist: /var/www/favicon.ico Location Access and error log files are stored on individual web servers. The exact location of your Apache logs depends on your operating system: Debian/Ubuntu/Linux Mint apache logs error Redhat/Fedora/CentOS Configuration OpenSUSE General Configuration The following general default logging configuration directives are specified in absence of specific virtual host container configuration. Log Level Directive This specifies log message severity. Default is “warn.” LogLevel warn Table of Level Severities Severity Description Example emerg Emergencies — system is unusable “Child cannot open lock file. Exiting” alert Immediate action required “getpwuid: couldn’t determine user name from uid” crit Critical conditions “socket: Failed to get a socket, exiting child” error Error conditions “Premature end of script headers” warn Warning conditions “child process 1234 did not exit, sending another SIGHUP” notice Normal but significant condition “httpd: caught SIGBUS, attempting to dump core in …” info Informational “Server seems busy…” debug Debug-level messages “opening config file …” trace1-8 Trace messages “proxy: FTP: … ” Note regarding a particular level: Levels are listed in order of descending severity. When triggered, a configured log level will log all events of that level or greater. Log Format Apache offers a ton of flexibility for what you can log.
