SquidGuard is a URL redirector used to use blacklists with the proxysoftware Squid. There are two big advantages to squidguard: it is fast and it is free.

Installation
In addition to the basic development tools, there's a few other dependencies:
yum install ncurses-devel pcre-devel libtool python-docutils readline-develDownload the Varnish source code:
cd /extra/src
wget https://repo.varnish-cache.org/source/varnish-4.1.3.tar.gz
tar zxf varnish-4.1.3.tar.gz
cd varnish-4.1.3Configure and build it:
./configure
makeIf you want, you can run the tests before installing:
cd bin/varnishtest
./varnishtest tests/*.vtcThen install it:
make installVarnish will now be installed in /usr/local. The varnishd binary is in /usr/local/sbin/varnishd and its default configuration will be /usr/local/etc/varnish/default.vcl.
You can start up varnish to test it out using but you must enable a backend in /usr/local/etc/varnish/default.vcl:
varnishd -f /usr/local/etc/varnish/default.vcl -s malloc,1G -T 127.0.0.1:2000 -a 0.0.0.0:8080Automatic Startup
There's a number of different ways to get Varnish to start automatically (rc.d/init.d script, rc.local, xinetd). We're going to use daemontools.
If you haven't already, install daemontools.
Create a directory for the Varnish service:
mkdir -m 1755 /var/service/varnish
cd /var/service/varnishCreate the run script and make it executable:
echo '#!/bin/sh' > run
echo 'exec 2>&1' >> run
echo 'exec varnishd -F -f /usr/local/etc/varnish/default.vcl -s malloc,1G' >> run
chmod 755 runOur log script comes from John Simpson's:
mkdir -m 755 log
cd log
wget http://qmail.jms1.net/scripts/service-any-log-run
mv service-any-log-run run
chmod 755 runFinally, add the service to daemontools by creating the symbolic link in /service
ln -s /var/service/varnish /service/varnishConfirm that the service is running:
svstat /service/varnish /service/varnish/logResources
