Speed up Apache Website with Varnish HTTP Cache

Introduction.


Varnish is reverse-proxy Accelerator is a web application that is also known as temporary proxy HTTP cache scope and makes the website very fast. Depending on the architecture used, it can make site 4-8 times faster.

Before Installation Requirements.

- Apache web-server installed.
- Need EPEL repositories installed for Cantos/RHEL. No need for Ubuntu.

Centos/RHEL 
sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm 

Install varnish.

Centos/RHEL 

sudo yum install varnish                                             

Ubuntu

sudo apt-get install varnish                                          

After installing Varnish, stop, start and enable varnish service

sudo systemctl stop varnish                                         
sudo systemctl start varnish                                         
sudo systemctl enable varnish                                       

  

Configuration

To work together, we must regulate both varnish and Apache.


Configure varnish to use port 80

Open varnish configuration file for change pot,

sudo nano /etc/varnish/varnish.params                                  For CentOS/RHEL
sudo nano /etc/default/varnish                                                      For Ubuntu

change the port from 6081 to 80,

Save the file when you’re done.
Next, open the default.vcl file

sudo nano /etc/varnish/default.vcl      

And make following changes,

#Default backend definition. Set this to point to your content server.
backend default {
.host = "127.0.0.1";
.port = "8080";
}

Save and close file

Then, Restart both Varnish

sudo systemctl restart varnish                                       


Switch apache2 default port to 8080 

Open ‘httpd.conf’

sudo vim /etc/httpd/httpd.conf                                      

change the port 80 to 8080

Listen 8080

Restart the Apache service to apply the changes.

sudo systemctl restart httpd For                                           For CentOS/RHEL
sudo systemctl restart apache2                                                     For Ubuntu

Now everything is setup perfectly.
Varnish should be the listen of port 80.
Execute the this command for test configuration.

curl -I http://localhost


Output is something like this,


HTTP/1.1 200 OK
Date: Sun, 10 Oct 2018 18:50:37 GMT
Server: Apache/2.4.25 (Ubuntu)
Last-Modified: Sun, 10 Oct 2018 18:30:12 GMT

What is a CDN ? How Does a content delivery network Work?

Why AWS (amazon cloud) is better for Cloud Servers?

The Amazon Web Services provides remote computing services. Most important and well-known service is the Amazon S3 and Amazon EC2. I have compiled some of the reasons for the AWS choice as Cloud Server, for big and small users.   Pricing Model : Pay-As-You-Go. I am only pay for that what I use. Let’s take an example to understand this: In AWS infrastructure I am using 13GB, now usually what happens with other cloud service I estimate my usage say 40GB, reserve it, and pay for that 40GB monthly. And with AWS, I am not using the whole 40GB. I just have 13GB of data, so I just pay for that 13GB, and I can always store more as your requirements grow, there is no restriction!     Security. Cloud security at AWS is the highest priority Amazon cloud is a secure, durable technology platform with industry-recognized certifications and audits: PCI DSS Level 1, ISO 27001, FISMA Moderate, FedRAMP, HIPAA, and SOC 1 (formerly referred to as SAS 7...
