for in log files. Some log files are controlled by a daemon called syslogd. A list of log messages maintained by syslogd can be found in the /etc/syslog.conf configuration file. 35.1. Locating Log Files Most log files are located in the /var/log/ directory. Some applications such as httpd and samba have a directory within /var/log/ for their log files. You may notice multiple centos error log apache files in the log file directory with numbers after them. These are created when the log files are rotated. Log files are rotated so their file sizes do not become too large. The logrotate package contains a cron task that automatically rotates log files according to the /etc/logrotate.conf configuration file and the configuration files in the /etc/logrotate.d/ directory. By default, it is configured to rotate every week and keep four weeks worth of previous log files. Prev34.3. Additional Resources Up Home Next35.2.

According to a website that I read, it should be at /var/log/httpd/error_log But I don't have the httpd directory on /var/log apache-2.2 share|improve this question asked Oct 8 '10 at 22:05 valter 1862721 It is where you described it. Probably you never started http://serverfault.com/questions/189205/where-can-i-find-apache-error-log-on-centos apache and therefore this directory did not get created. Or you have you custom build configuration. Did you maybe install some hosting control panel software? –Raffael Luthiger Oct 8 '10 at 22:13 add a comment| 3 Answers 3 active oldest votes up vote 6 down vote accepted Check your httpd.conf The LogFile variable tells you where apache is writing logs. This value is often (always?) relative to the ServerRoot variable. share|improve this answer answered Oct 9 '10 at 0:13 tim 45624 add a comment| up vote 5 down vote Chances are it's in /var/log/httpd. Do you have locate installed? Have you run updatedb recently, or have it cronified? If so, you can do locate error_log. share|improve this answer answered Oct 9 '10 at 0:26 Andy Lester 453213 add a comment| up vote 3 down vote take a look at your /etc/httpd.conf file and check where you are writing your logs valter. as Raffael says it maybe that you've got them being written to odd locations. check that your httpd server actually started too! :-) share|improve this answer answered Oct 8 '10 at 22:20 Khushil 498310 I found the following line on httpd.conf, in other server: ErrorLog logs/error_log –valter Oct 8 '10 at 22:42 2 check in /
