How To Install Squid on Fedora 23

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.

Pre-Flight Check

• These instructions are intended specifically for installing Squid on a single Fedora 23 node. If you’re using a different operating system, check out our guides to installing Squid on Fedora 21, Ubuntu 14.04, and CentOS 7.
• We’ll be logging in as root to a Liquid Web Self Managed Fedora 23 server.

Step #1 Install Squid

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

dnf -y update

Now we’ll install Squid and related packages with:

dnf -y install squid

Step #2: Verify the Squid Installation

Use the following command to view information about the ‘squid’ 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:

Step #3: Start Squid and Configure it To Start on Boot

To start Squid:

systemctl start squid

Set Squid to start at boot:

systemctl enable squid

To check the status of Squid:

systemctl status squid

To stop Squid:

systemctl stop squid
