1. Execute follow instruction:
http://ubuntuserverguide.com/2012/05/how-to-install-and-configure-proxy-server-with-squid3-on-ubuntu-server-12-04-lts.html
Installing Squid3
Log in on Ubuntu Server, then type command below to Install squid2 in ubuntu server 12.04:
sudo apt-get install squid3 ccze
Configure Squid3
Create directory for Cache, on this case cache directory placed on directory /home/precise/cache/. Then change the permissions cache directory to 777 and owner proxy:proxy
sudo mkdir -p /home/precise/cache/
sudo chmod 777 /home/precise/cache/
sudo chown proxy:proxy /home/precise/cache/
Before editing squid configuration, Make a backup of your /etc/squid3/squid.conf file for future reference. Squid.conf has nearly all the options listed and it is recommended to go through that file to know more about squid options.
sudo cp /etc/squid3/squid.conf /etc/squid3/squid.conf.origin
sudo chmod a-w /etc/squid3/squid.conf.origin
Now edit /etc/squid3/squid.conf file, delete all options in /etc/squid3/squid.conf then replace with squid3 configuration below
sudo nano /etc/squid3/squid.conf
Squid3 configuration:
