Centos, Varnish, NGINX, Drupal

As an experiment this week I decided to change the web server of a site to NGINX, the existing web server was Apache. I would like to share the steps required to setup NGINX with Varnish to make your Drupal site run at a blazing speed.
Environment:
Centos 6
16G RAM
Quadcore processor.
Install NGINX
yum install nginx
Configure NGINX
Open /etc/nginx/nginx.conf
Add the following lines at the bottom of “http” block:

It will look something like:

Add host yoursitename.com
Create two directories sites-available and sites-enabled

Create a file named “yoursitename.com.conf” under sites-available and paste the following contents:


Please note that the port number is “81” as varnish will run at port 80 and will behave like content server.

Create a symlink and remove the default configuration:

Please note that default.conf’s location can be different based on different platforms.

Change owner of the web directory

Install Varnish


Configure Varnish

Open /etc/sysconfig/varnish, replace the following values:

Keep all other values as it is.

Open /etc/varnish/default.vcl and update “backend default” block to the following:

Install PHP FPM

I am also using php fpm for faster php processing. Here is the command for that, simple simple

Restart servers:

Configure Varnish with Drupal

Install Drupal’s varnish module
Add the following lines to your settings.php:

Go to varnish configuration: admin /config /development /varnish

Set Varnish control terminal: 127.0.0.1:6082
Set Varnish Control key from/etc/varnish/secret
Please make sure the “Varnish running” is ticked.
Awesome, you are done. Enjoy the faster response times of your site.
