    How To Install Varnish 4 on CentOS 7

    Varnish is a proxy and cache, or HTTP accelerator, designed to improve performance for busy, dynamic web sites. By redirecting traffic to static pages whenever possible, varnish reduces the number of dynamic page calls, thus reducing load.

    Step 1: Add the EPEL Repository

    Varnish is part of Extra Packages for Enterprise Linux (EPEL), which is a community repository of non-standard packages for the RHEL distribution. First, we’ll install the EPEL repository:

    rpm -iUvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm

    Step 2: Install Varnish

    First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new.

    yum -y update

    At this point, installing Varnish is as simple as running just one command:

    yum -y install varnish

    Step 3: Start Varnish

    To configure varnish to start at boot, run the following command:

    systemctl enable varnish

    To start varnish, run the following command as root:

    systemctl start varnish

    To check the status of varnish, run the following command as root:

    systemctl status varnish

    Check the version of Varnish that is running:

    varnishd -V

    Varnish is configured to listen on port 6081 by default. It expects your web server to be local, or on the same serve,r and listening on port 8080.

    Step 4: Configuration File Locations

    A basic and default configuration file can be found at:

    /etc/varnish/default.vcl

    An example configuration can be found in example.vcl:

    /usr/share/doc/varnish-4.0.1/example.vcl

    To view or edit example.vcl:

    vim /usr/share/doc/varnish-4.0.1/example.vcl
