# cp /opt/smokeping/etc/basepage.html.dist /opt/smokeping/etc/basepage.html

Create directories used by smokeping, copy some required files into the public web-directory and set rights for apache user if required.

# mkdir /opt/smokeping/data
# mkdir /opt/smokeping/var
# mkdir /var/www/smokeping
# mkdir /var/www/smokeping/cache
# cp -R /opt/smokeping/htdocs/* /var/www/smokeping
# mv /var/www/smokeping/smokeping.fcgi.dist /var/www/smokeping/smokeping.fcgi
# chown -R apache:apache /var/www/smokeping

Add a virtual apache directory by creating a file on /etc/httpd/conf.d/ with the name smokeping.conf. Add following content to it

Alias /smokeping "/var/www/smokeping"

<Directory /var/www/smokeping>
Options Indexes FollowSymLinks MultiViews ExecCGI
