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

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

LogFile /var/log/apache/access.log.1

to

LogFile /var/log/apache2/access.log

2. 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…
3. 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
