This tutorial shows you how to perform an initial installation of Varnish Enterprise 6.0 on Red Hat Enterprise Linux (RHEL) 9, AlmaLinux 9 and Rocky Linux 9. Looking for another platform?
Before starting this tutorial, you should have:
Create the file /etc/yum.repos.d/varnish-software.repo
with the following:
[varnish-enterprise-6.0]
name=Varnish Enterprise
baseurl=https://TOKEN:@packagecloud.io/varnishplus/60/el/9/x86_64
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://TOKEN:@packagecloud.io/varnishplus/60/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
Enable the Extra Packages for Enterprise Linux (EPEL) repository by installing the epel-release
package:
sudo dnf install epel-release
Install Varnish Enterprise and VMODs:
sudo dnf install varnish-plus
The package varnish-plus-vmods-extra
is optional and comes with VMODs that have additional dependencies. In EL9, some of these dependencies are satisfied by packages from the Code Ready Builder (CRB) repository. If you’d like to install varnish-plus-vmods-extra
, please enable the CRB repository first:
# Only needed if dnf config-manager is not installed
sudo dnf install -y 'dnf-command(config-manager)'
sudo dnf config-manager --set-enabled crb
sudo dnf install varnish-plus-vmods-extra
The configuration files for Varnish are:
/etc/varnish/default.vcl
The VCL configuration file that is loaded by default when Varnish starts. In this file, you can specify the location of your web servers.
/usr/lib/systemd/system/varnish.service
The systemd unit file specifying Varnish parameters, storage engines, and the VCL configuration file to load on startup. This file should not be edited, but overridden according to systemd best practices.
Varnish starts, stops, restarts, and reloads using the following commands:
sudo systemctl start varnish
sudo systemctl stop varnish
sudo systemctl restart varnish
sudo systemctl reload varnish
Verify if Varnish is running using the following command:
sudo systemctl status -l varnish
Varnish Enterprise 6.0 has now been installed. At this point, it is possible to dive in to VCL and VMODs.
