Step1. Squid3 install.

apt-get install squid3

Step2. Rename the original squid.conf for backup:

mv /etc/squid3/squid.conf /etc/squid3/squid.conf.back

Step3. Create a new custom file squid.conf:

nano /etc/squid3/squid.conf

and paste the following content:

http_port 3128 transparent
acl localhost src 127.0.0.0/8
http_access allow localhost
cache_dir ufs /var/spool/squid3 7000 16 256

auth_param basic program /usr/lib/squid3/squid_db_auth –user userproxy –password parolaproxi –plaintext –persist
auth_param basic children 5
auth_param basic realm This is a welcome message that will me displayed to each user.
auth_param basic credentialsttl 1 minute
auth_param basic casesensitive off

acl db-auth proxy_auth REQUIRED
http_access allow db-auth
http_access allow localhost
http_access deny all

Step4. We will go now to the MySQL and create the database:

Squid is used by hundreds of Internet Providers world-wide to provide their users with the best possible web access. Squid optimises the data flow between client and server to improve performance and caches frequently-used content to save bandwidth.

Squid can also route content requests to servers in a wide variety of ways to build cache server hierarchies which optimise network throughput.

Step 1. Install  Squid

apt-get install squid

Step 2. Allow your network to use the proxy server.

Append lines similar to these to your config.
