How to Install and Configure Lusca as Proxy Server in Ubuntu Server 12.04

by -11 views

Step 1 . Install Ubuntu Server 12.04 and use manual partition with following partition table ( In this case I have 250 GB HDD and RAM 4 GB)

Type Size Location FileSystem Mount
Primary 30 GB Beginning ext4 /
Primary 500 MB Beginning ext4 /boot
Primary 8192 MB Beginning swap swap
Logical 25 GB End btrfs /cache-1
Logical 25 GB End btrfs /cache-2
Logical 25 GB End btrfs /cache-3
Logical 25 GB End btrfs /cache-4
Logical 25 GB End btrfs /cache-5
Logical 46 GB End ext4 /home
Logical 5 GB End ext4 /opt
Logical 5 GB End ext4 /srv
Logical 5 GB End ext4 /tmp
Logical 5 GB End ext4 /usr
Logical 5 GB End ext4 /usr/local

Step 2. Make sure your ubuntu package repositories and installed programs are up to date.

[codesyntax lang="php"]
sudo apt-get update -y && sudo apt-get upgrade -y
[/codesyntax]
Step 3. Install Lusca and other package

[codesyntax lang=”php”]

sudo apt-get install lusca squidclient squid-cgi ccze

[/codesyntax]

Step 4. Create lusca file configuration:
[codesyntax lang=”php”]

sudo /etc/lusca/squid.conf /etc/lusca/squid.conf.original
sudo touch /etc/lusca/squid.conf

sudo nano /etc/lusca/squid.conf

[/codesyntax]

Use the following Lusca File Configuration:

[/codesyntax]
Set owner file /etc/lusca/squid.conf to user and group proxy
[codesyntax lang=”php”]

sudo chown proxy:proxy /etc/lusca/squid.conf

[/codesyntax]
Step 5. Create Store Url File Configuration:
[codesyntax lang=”php”]

sudo mkdir /etc/squid/
sudo touch /etc/squid/storeurl.pl
sudo nano /etc/squid/storeurl.pl

[/codesyntax]
Use the following store url file configurations
[codesyntax lang=”php”]
