Apt-cacher need Apache to be properly installed.
On Debian systems, apt-cacher can be installed using apt. Apache should be restarted afterwards.
# apt-get install apt-cacher
# /etc/init.d/apache2 restart
You can also get the latest DEBs from pool/main/a/apt-cacher/ directory of any Debian mirror.
If everything goes well, the path /apt-cacher on the web server should be accessible from any browser.
# rm -rf /usr/share/apt-cacher # just in case
# mv apt-cacher-1.4.1 /usr/share/apt-cacher
# cd /usr/share/apt-cacher/
# mv apache.conf /etc/httpd/conf.d/apt-cacher.conf
# chmod 644 /etc/httpd/conf.d/apt-cacher.conf
# chown root:root /etc/httpd/conf.d/apt-cacher.conf
# /etc/init.d/httpd restart
# mv apt-cacher2 apt-cacher
# mkdir /etc/apt-cacher
# mv *.conf /etc/apt-cacher/
# ./install.sh
# chown -R apache /var/log/apt-cacher/
# chown -R apache /var/cache/apt-cacher/
