Navigate to your public_html directory by running the following command

cd public_html
vi .htaccess
Options +FollowSymLinks
ln -s ~/tmp/webalizer/<subdomain>/ stats

you can replace the "stats" part of that command with name you want to use in order to access your website statistics.

After that, run the following commands
chmod 755 ~/tmp
chmod 755 ~/tmp/webalizer
now you can access www.yoursite.com/stats/
