Question
how to Install Varnish on Ubuntu 14.04.1 LEMP
Hello,
i m running one wordpress site on 512 droplet. i want install varnish for my droplet and i believe i must do some extra things also so that varnish can cache my wordpress site efficiently. just like its described in the following tutorial
https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-nginx-php-and-varnish-on-ubuntu-12-04
now my questions are the following
Q1. How can i install varnish for my nginx server which is on ubuntu 14.04.1? i tried to follow the above tutorial which is for 12.04 but that didnt work. says not supported when i try to install varnish. maybe that procedure not supported anymore for 14.04.1 or maybe because that is for varnish v3.
Q2. Currently Opcache code is enabled and its set to following parameter
opcache.memoryconsumption=128
opcache.maxacceleratedfiles=4000
opcache.revalidatefreq=60
should i change them to default or keep them as it is? or i simply dont need Opcache anymore?
Q3. i need to add one sub-domain that will bypass varnish cache and hit directly to my nginx server which is on default port 80.

At what point in the tutorial are you seeing the message that it is not supported?
@ryanpq
when i follow that tutorial i get error at
sudo apt-get install varnish libvarnish-dev
from varnish support i followed new instruction to install varnish 4.0 which is for ubuntu 14.04 and then i was able to install varnish. then i followed again next parts of varnish configuration from the above tutorial and then i get this msg when i tried to start varnish.

From Varnish documentation :
So with varnish 4.0 the beginning of the default.vcl file should look like this:
After that Varnish started !
