Implementing Varnish Cache
==========================

.. contents::

Install varnish
---------------

.. code-block:: bash

sudo apt-get install varnish

Make varnish listen to port 80
------------------------------

Also disable the varnish admin port

.. code-block:: bash

sudo cp -p /etc/default/varnish /etc/default/varnish.ORIG sudo vim
/etc/default/varnish

| diff /etc/default/varnish /etc/default/varnish.ORIG 40c40,41 <
  DAEMON_OPTS=“-a :80
  — > DAEMON_OPTS=”-a :6081
| > -T localhost:6082

Make Apache2 vhosts listen to port 8080
---------------------------------------

.. code-block:: bash

cp -p /etc/apache2/ports.conf /etc/apache2/ports.conf.ORIG sudo vim
/etc/apache2/ports.conf diff /etc/apache2/ports.conf
/etc/apache2/ports.conf.ORIG 8c8 < NameVirtualHost *:8080 — >
NameVirtualHost* :80 10c10 < Listen 8080 — > Listen 80

Now edit all the vhost files with two commands:

.. code-block:: bash

cd /etc/apache2/sites-available sudo perl -pi -w -e ‘s/:80/:8080/g;’ \*

The above command performs a search and replace on every file in the
directory changing :80 to :8080

Restart Daemons
---------------

.. code-block:: bash

sudo service apache2 restart sudo service varnish restart
