How To Install Squid Proxy on AlmaLinux 8

Install Squid Proxy on AlmaLinux 8

In this tutorial, we will show you how to install Squid Proxy on AlmaLinux 8. For those of you who didn’t know, Squid Proxy is an open source caching proxy for the web. It supports many protocols such as HTTP, HTTPS, FTP and more. By caching and reusing frequently-requested web pages, squid saves bandwidth and improves response time making accessing web pages very fast.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Squid Proxy server on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.

Install Squid Proxy on AlmaLinux 8

Step 1. First, let’s start by ensuring your system is up-to-date.

sudo dnf update
sudo dnf install epel-release

Step 2. Installing Squid Proxy on AlmaLinux 8.

By default, Squid is available on AlmaLinux 8 base repository. Now run the following command to install Squid Proxy to your system:

sudo dnf install squid

Verify Squid Proxy installation:

squid --version

Before starting the configurations, make sure that Squid services are running on your system. Run the following command to check Squid services status:

sudo systemctl start squid
sudo systemctl enable squid
sudo systemctl status squid

Step 3. Configuring Squid Proxy.

Now we open Squid proxy configuration file:

sudo nano /etc/squid/squid.conf

Find the http_port directive if you’d like to change the listening port for Squid. By default, it is already set to port 3128:

# Squid normally listens to port 3128
http_port 3128
# http_port 3128 transparent

Save and close, then restart the Squid server so that the changes take place:

sudo systemctl restart squid

Step 4. Configure Firewall.

If your firewall is active, you will need to allow Squid through the firewall for other systems to connect:

sudo firewall-cmd --add-service=squid --permanent
sudo firewall-cmd --reload

Step 5. Configure Browser to Use Squid proxy.

Once successfully installed and set up, now time to test browsing pointing squid IP and default port in the client browser. On your Firefox, configure it to connect to the external network via your Squid server. Preferences -> General -> Network Settings -> Manual Proxy Configuration. Check to Use this proxy server for all protocols.

Congratulations! You have successfully installed Squid. Thanks for using this tutorial for installing the Squid proxy server on your AlmaLinux 8 system. For additional help or useful information, we recommend you check the official Squid website.
