Configuring Varnish to work with Apache on Ubuntu 14.04 is largely similar to this article covering 12.04.
I just ran through a basic set up on 14.04. The first step is to install Apache and Varnish:
sudo apt-get install varnish apache2
Then we need to configure Varnish to listen on port 80. Edit the file /etc/default/varnish Find the section begin with "Alternative 2, Configuration with VCL" Make sure it's uncommented and update the port:
DAEMON_OPTS="-a :80 \
-T localhost:6082 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s malloc,256m"
Next we need to adjust Apache to listen on port 8080. Edit /etc/apache2/ports.conf and change Listen 80 to Listen 8080 Then edit /etc/apache2/sites-enabled/000-default.conf and change <VirtualHost *:80> to <VirtualHost *:8080>
Finally, restart Varnish and Apache with:
sudo service apache2 restart
sudo service varnish restart
Varnish is now sitting in front of Apache and serving cached content.
Varnish is an HTTP accelerator and a useful tool for speeding up a server, especially during a times when there is high traffic to a site. It works by redirecting visitors to static pages whenever possible and only drawing on the virtual private server itself if there is a need for an active process. This tutorial covers setting up Varnish with Apache on Ubuntu 12.04.

Nice. Should it be any performance increase to run varnish on a separate VPS?
Like this guide?
Varnish Cache is a caching HTTP reverse proxy, or HTTP accelerator, which reduces the time it takes to serve content to a user. In this tutorial, we will cover how to use Varnish Cache 4.0 to improve the performance of your existing web server. We will also show you a way to add HTTPS support to Varnish, with Nginx performing the SSL termination. -
It really depends on your needs. As Varnish caches content in memory, the main consideration for whether or not to split it out onto another server would be memory usage.

how about if I have multiple virtual host / domain?
for the example I have an IP : 111.111.111.111 , then i have domain.com , domain2.com, sub.domain.com, sub.domain2.com . is configuration still same? -
I have run up a 1404 droplet with Magento using SSL. Should I change the 'magneto-ssl.conf' from 443 to 8080? I feel like I need to leave it at 443 for ssl to work properly.

@saulpublic HTTPS traffic needs to be on port 443. Generally, you'll want to set up Apache or Nginx to listen on 443 for SSL termination with a proxy back to Varnish on localhost. This article uses Nginx, but explains the concepts:
You could accomplish something similar with Apache using:
<VirtualHost *:443> ServerName www.example.com ProxyPreserveHost On ProxyPass / http://127.0.0.1:80/ RequestHeader set X-Forwarded-Port "443" RequestHeader set X-Forwarded-Proto "https" SSLEngine On SSLCertificateFile /etc/apache2/ssl/example.com.crt SSLCertificateKeyFile /etc/apache2/ssl/example.com.key SSLCertificateChainFile /etc/apache2/ssl/example.com.chain </VirtualHost>This way, Apache deals with the SSL while Varnish is still serving cached content.

For Varnish to work on Ubuntu 15.04.
First grep:
```sudo grep -R 'ExecStart=/usr/sbin/varnishd' /etc/
If result is "/etc/systemd/system/multi-user.target.wants/varnish.service"
```sudo nano /etc/systemd/system/multi-user.target.wants/varnish.service
Change the ExecStart to this only.
```ExecStart=/usr/sbin/varnishd -a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,256m
Save and exit, restart Varnish.
```systemctl daemon-reload
systemctl restart varnish.service
I'm using ubuntu 16 , and having link problems:
http://example.com/test is redirecting to http://example.com:8080/test and returning error :|
Have another answer? Share your knowledge.
I followed these instructions and my site is being served however I'm not seeing any varnish headers. Am I missing a step?
Thanx
