cara Installing SQUID / LUSCA in UBUNTU

1# Installing SQUID / LUSCA in UBUNTU


I assume your ubuntu box have 2 interfaces configured, one for LAN
and second for WAN. You have internet sharing already configured. Now
moving on to LUSCA / SQUID installation.

Download LUSCA source and compile it using,

mkdir /temp
cd /temp
wget http://lusca-cache.googlecode.com/files/LUSCA_HEAD-r14809.tar.gz
tar xzvf LUSCA_HEAD-r14809.tar.gz
Update & Install some tools for ubuntu

sudo apt-get update
sudo apt-get install gcc build-essential sharutils ccze libzip-dev automake1.9
cd LUSCA_HEAD-r14809
Now compile LUSCA with following options

./configure '--prefix=/usr/local/squid' '--enable-removal-policies=heap,lru' '--disable-dependency-tracking' '--disable-arp-acl' '--disable-cache-digests' '--enable-cachemgr-hostname=localhost' '--disable-delay-pools' '--enable-epoll' '--enable-external-acl-helpers=ip_user' '--disable-ident-lookups' '--enable-linux-netfilter' '--disable-referer-log' '--enable-removal-policies=heap,lru' '--disable-snmp' '--disable-ssl' '--enable-storeio=aufs,null,coss' '--disable-useragent-log' '--disable-wccpv2' '--with-aio' '--with-maxfd=1048576' '--with-dl' '--with-pthreads' 'build_alias=i686-redhat-linux-gnu' 'host_alias=i686-redhat-linux-gnu' 'targe_alias=i686-redhat-linux-gnu''--enable-truncate' '--disable-unlinkd' '--with-large-files' '--disable-htcp'
sudo make all
sudo make install
All of Lusca/Squid configuration files can be found at

/usr/local/squid/etc/
and squid executable can be found at
/usr/local/squid/sbin/

Now We will edit squid.conf file to make it customize according to our requirements by . . .

nano /usr/local/squid/etc/squid.conf
Delete all previously lines , and paste the following lines.

Remember following squid.conf is
not very neat and clean , you will find many un necessary junk entries
in it, but as I didn’t had time to clean them all, so you may clean them
as per your targets and goals.

# Cache Directory , modify it according to your system.
# but first create directory in root by mkdir /cache1
# and then issue this command chown proxy:proxy /cache1
# [for ubuntu user is proxy, in Fedora user is SQUID]
# I have set 500 MB for caching reserved just for caching ,
# adjust it according to your need.
# My recommendation is to have one cache_dir per drive. zzz

Now create cache dir and logs files , and assign them necessary permissions.

mkdir /cache1
chown proxy:proxy /cache1
mkdir /var/log/squid
chmod 777 /var/log/squid

Now initialize cache dir by

/usr/local/squid/sbin/squid -z
SOTEURL.PL


Now We have to create an important file name storeurl.pl , which is very important and actually it does the
main job to pull video from cache.

mkdir /etc/squid
touch /etc/squid/storeurl.pl
chmod +x /etc/squid/storeurl.pl
nano /etc/squid/storeurl.pl
Now paste the following lines, then Save and exit.
