This guide will walk you through how to install Squid Proxy server on CentOS 8 / RHEL 8 Linux. Squid is a web proxy server application that gives organizations proxy and cache services for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. It runs on the most available operating systems, including Windows and is licensed under the GNU GPL. To install Squid on a CentOS 8/RHEL 8 server, proceed by following these steps.
Squid proxy servers run on most conventional operating systems, such as the various Linux distributions, Mac OS X or Windows. Operating the proxy server can either be done via the corresponding command line tool or a graphical user interface, like GAdmin SQUID.
Step 1: Update your server
Let us make sure our house is completely fresh before we embark on getting our server installed in a comfortable place.
Step 2: Install Squid
Squid is available on Yum repositories. Run the command below to install it in our clean server.
Step 3: Configure forward proxy settings
You send a connection request to a forward proxy, and then it retrieves data from the internet on your behalf. This way, it can act as a caching server as well by keeping all the pages being frequently visited within it. Next time you access pages that have been cached, your request does not need to go all the way to the internet. The browser retrieves it from the cache.

Squid has extensive access controls and makes a great server accelerator. It runs on Unix and Windows and is licensed under the GNU GPL.
- Squid proxies are popular with many SSH and VPN providers and are mostly offered for free. Setting up with web browsers and apps that support Squid in combination with VPN tunnels and SSH servers can improve overall browsing speed. It can also be useful to get around corporate network restrictions or ISP blockages. Squid proxy server caches web.
Before we go on, let us back up the default configuration file.
Open squid’s main configuration file and add/edit the following
Comment out all of the default network ACL’s as shown below
Configure the cache type, the path to the cache directory, the cache size, and further cache type-specific settings in the cache_dir parameter.

Test if your proxy works. It should download the index.html file
Step 5: Configure CentOS client
On your CentOS client, you have the option of setting the proxy server system-wide or on a per-application basis. In order not to waste a lot of time doing the per-application basis, let us set our proxy server system-wide.
Open the file below and add the settings accordingly
Add proxy settings:
Then source the file
Now we have our Squid Proxy installed. Play around with it and check out what it can achieve in your set up. If you’d like to build more stuff, please throw your eyes below for the guides shared. We appreciate your stay on the blog and we hope it was helpful.
