How to Install Squid (Caching / Proxy) on Fedora 20

Squid is a caching and forwarding web proxy. It is most often used in conjunction with a traditional LAMP stack (Linux, Apache, MySQL, PHP), and can be used to filter traffic on HTTP, FTP, and HTTPS, and increase the speed (thus lower the response time) for a web server via caching.

• These instructions are intended specifically for installing Squid on a single Fedora 20 node.
• I’ll be working from a Liquid Web Self Managed Fedora 20 server, and I’ll be logged in as root.

First, clean-up yum:

yum clean all

As a matter of best practice we’ll update our packages:

yum -y update

Installing Squid and related packages is now as simple as running just one command:

yum -y install squid

Squid should start immediately after the installation. Use the following command to view information on the command:

squid -h

Use the following command to check the version number of Squid and the configuration options it was started with:

squid -v

Your results should appear similar to:

And then start Squid:

systemctl start squid

Be sure that Squid starts at boot:

systemctl enable squid

To check the status of Squid:

systemctl status squid

To stop Squid:

systemctl stop squid
