Hi there! Are you looking to build an Apache server with Squid? If so, you have come to the right place. In this article, we will guide you through the step-by-step process of building an Apache server with Squid.

Introduction

Apache is an open-source web server software that powers a significant portion of websites on the internet. Squid is a caching proxy server that improves website browsing performance and security. Combining Apache with Squid can enhance web server performance and reduce the load on the server.

Prerequisites

Before we start building the Apache server with Squid, we need to ensure that we have the following prerequisites:

Prerequisite	Description
Operating System	We will be using Ubuntu Server 18.04 for this tutorial
Root Access	You need to have root access to the Ubuntu Server
Internet Connection	Your Ubuntu Server must have access to the internet

Step-by-Step Guide

Step 1: Installing Apache

The first step is to install the Apache web server on Ubuntu Server. To install Apache, follow the instructions below:

1. 1. Open a terminal window on Ubuntu Server by pressing Ctrl+Alt+T.
   2. Run the following command to update the package list:

sudo apt-get update

1. 1. Install Apache using the following command:

sudo apt-get install apache2

1. 1. After the installation is complete, start Apache by running the following command:

sudo systemctl start apache2

1. To check if Apache is running, open a web browser on a different device and enter the IP address of the Ubuntu Server. You should see the Apache default page.

Step 2: Configuring Apache

After installing Apache, we need to configure it to work with Squid. To do this, follow the instructions below:

1. 1. Open the Apache configuration file by running the following command:

sudo nano /etc/apache2/apache2.conf

1. 1. Add the following lines to the end of the file:

ProxyRequests On

ProxyVia On

<Proxy *>

Order deny,allow

Deny from all

Allow from 192.168.0.0/24

</Proxy>

1. 1. Save and close the file.
   2. Restart Apache by running the following command:

sudo systemctl restart apache2

Step 3: Installing Squid

The next step is to install Squid on Ubuntu Server. To install Squid, follow the instructions below:

1. 1. Open a terminal window on Ubuntu Server.
   2. Run the following command to update the package list:

sudo apt-get update

1. 1. Install Squid using the following command:

sudo apt-get install squid

1. 1. After the installation is complete, start Squid by running the following command:

sudo systemctl start squid

Step 4: Configuring Squid

Now that we have installed Squid, we need to configure it to work with Apache. To do this, follow the instructions below:

1. 1. Open the Squid configuration file by running the following command:

sudo nano /etc/squid/squid.conf

1. 1. Add the following lines to the end of the file:

http_port 3128

http_access allow all

cache_dir ufs /var/spool/squid 100 16 256

cache_mem 128 MB

maximum_object_size 512 MB

cache_replacement_policy heap LFUDA

cache_peer 192.168.0.101 parent 80 0 no-query originserver

never_direct allow all

1. 1. Save and close the file.
   2. Restart Squid by running the following command:

sudo systemctl restart squid
