Webalizer Configuration for apache in Linux
Introduction:
The Webalizer is a GPL application that generates web pages of analysis, from access log. It is simple to configure and easy to run.
Release:
RedHat Enterprise Linux
Problem:
Need to monitor the webserver hits using webalizer.
Solution:
1) Install the webalizer rpm
# yum install webalizer
2) Mention the webserver log path in the webalizer configuration file
# vi /etc/webalizer.conf
LogFile /etc/httpd/logs/access_log.2.gz
OutputDir /opt/webalizer_apache
Incremental yes
IncrementalName webalizer.current
Note: For my webserver i used logrotate to rotate all my logs. So i mentioned the rotated log file to update the hits. We can mention any webserver access log file (if you didn't have logrotate "/etc/httpd/logs/access_log" will be your default log location of apache webserver). "Incremental" keyword allows to rotate the logs.
3) Logrorate script used by me is
# vi /etc/logrotate.d/apache
/etc/httpd/logs/*log {
missingok
daily
rotate 20
compress
notifempty
sharedscripts
postrotate
/bin/kill -HUP `cat /etc/httpd/logs/httpd.pid 2>/dev/null` 2> /dev/null || true
endscript
}
Note: If you want to know more about logrotate refer http://linuxnextgen.blogspot.com/2011/04/logrotate-in-linux.html.
4) Log rotate will rotate the logs in every day morning. So i put one cron entry to update the webserver hits in the daily basics.
# crontab -e
4 30 * * * /usr/local/bin/webalizer -c /etc/webalizer.conf
5) In that output directory “index.html” file will be there using that we can browse webserver hits history
6) Or we can add the webalizer output directory to the webserver “Document Root” by creating one symbolic link.
# ln -s /opt/webalizer_apache /var/www/html/webalizer_apache
Note: Here “/var/www/html” is my “Document Root” in apache web server.
7) Now we can access the webalizer page from the webserver itself by using the below URL
