Install and configure webalizer on Ubuntu

1. install webalizer
   

   
   sudo apt-get install webalizer
   

   
   If webalizer is not found, you have to add sources in /etc/apt/sources.list: can comment the universe sources.
   


2. Enable the apache2 hostname resolution: go into /etc/apache2/apache2.conf: Change
   

   
   HostnameLookups Off
   

   
   into
   

   
   HostnameLookups On
   

   
   


3. By default webalizer is not well configured: it does not check in the good log. In /etc/webalizer.conf: Change
   

   
   LogFile         /var/log/apache2/access.log.1
   

   
   to
   

   
   LogFile         /var/log/apache2/access.log
   

   
   


4. Test webalizer:
   

   
   sudo webalizer
   

   
   If you get a warning like warning: Truncating ...
   It is because you did not put the hostnameLookup. If afterward, you get this message, it can be because you are attacked by a virus...
   


5. Run webalizer as a cronjob. This has to be run as root: Edit the root cronjobs by running the command:
   

   
   sudo crontab -e
   

   
   and add the line:
   

   
   0 * * * * webalizer
   

   
   With that line, every hour webalizer is run
