Add a web server

What is a Web Server?
• A powerful system which stores, processes and
delivers web content over a network which could be
either local network as intranet or internet.
A typical PC
(Desktop or Laptop)
+
IIS Server (Software)
=
Web Server

How it works…?
Web Pages
Web Server
Internet
Client
• It uses the client/server architecture and HypertextTransfer Protocol (HTTP)
for communication.

Client request consists of
several steps:
Web Browser
Web Server
File System
1. User Requests
document
• User requests document.
• Request message is parsed.
• Verify that request is authorized.
• URL in the request is associated
with a file document.
• Construct and transmit the
response.
How it works…?
2.Web Server looks
For document
in the file system

Server can generate the
response in different ways:
3.Web Server
retrieves
Document from file
system
• Server can simply retrieve the file
associated with the URL and returns the
content to the client.
• Server can invoke a script that
communicates with other servers or
back-end database to construct the
response message.
How it works…?
Web Browser
Web Server
File System
4.Web Server
returns document
data to web browser

Use of Web Server?
• Multiple website
• Multiple websites can be hosted on single web server with different port numbers assigned to
each web site.
• Server side scripting
• Server-side scripting language PHP would enhance business by producing dynamic contents.
• Security
• SSL (Secure Socket Layer) would add one more layer of security by encrypting sensitive
information.
• Failover
• IIS offers in-depth diagnostic tools such as failed request tracing, request monitoring and runtime
data.

Business Goal
• Web server provides server side coding capability.
• It provides high availability with no downtime to end clients.
• The web site can be running 24x7 including weekends and off-office
hours.
• By implementing Webserver, the server side deployments helps in
performance.
• Troubleshooting with the application is determined based on the logs
from the Web server.

Web Server Setup Environment
• Windows 7 operating system
• IIS Server 7
• Web Content:WordPress software package (v4.0)

Network Diagram
• A network diagram is a graphical representation of any
network.
• It’s a small structure of computers and network devices
(routers, modem, Ethernet etc.)
• It is a sequence of steps.

Design Features
• Configure IIS (Internet Information Services)Web server on
Windows 7 operating system.
• IIS is an extensible web server created by Microsoft.
• It is tightly integrated with Windows operating system.
• It supports many protocols such as HTTP, HTTPS, FTP, FTPS, SMTP
and NNTP.

Design Features
• Configure PHP (server-side language) to provide the
capability to create dynamic content.
• PHP is a server side scripting language which can be used to develop
web applications.
• The PHP database connection script connects to MySQL database to
store and retrieve website information.
• The generated content would be passed to the web server for display
to the user.

Design Features
• Configure MySQL (a database server) to provide the
capability to store content.
• MySQL is an open source relational database management system.
• It is one of the most popular databases and delivers reliable, high
performance web-based and embedded database applications.
• It is scalable and flexible and used by large corporations.
• It is known for its performance, cross platform compatibility, cost
and security.
• Database system would provide access to database to store and
organize site data and information.

Design Features
• Design company’s website usingWordPress and host it on the web server.
• WordPress is a Content Management System, use to create beautiful websites.
• Free to use and based on PHP and MySQL.
• Easy to use and maintain.WordPress admin panel can be used to easily add, update and
delete content to the website.
• Setup the windows firewall to secure the website from malicious attacks and
safety.
• A firewall is a system that prevents unauthorized access to or from a private network.
• By default windows firewall block all the connections including HTTP port 80 and HTTPS
443.

Design Features
• Setup SSL
• Intermediate layer between theTransport andApplication layer.
• Establishes secure connection between peers.
• Uses secure connection to transfer data from sender to recipient.
Transport Layer
Secure Socket Layer
Network Layer
HTTP SMTP POP3
80 25 110
HTTPS SSMTP SPOP3
443 465 995

Standards & Protocols
• HTTP (Hypertext transfer
protocol)
• HTTP is used between two
computers to transfer text from
hypertext links.
• HTTP works as request-response
protocol between the server and
user’s browser.
• Default port for HTTP is 80.

Standards & Protocols
• HTTPS (Hypertext transfer protocol over Secure
Socket Layer)
• Secure communication by encrypting sensitive data like
login details, credit card details.
• The connection from client-server and server-client is
secured using 128-bit SSL encryption.
• To enable this protocol, web server requires an SSL
Certificate.
• Default Port for HTTPS is 443.

Implementation Steps
• Installed IIS web server
• Installed PHP & MySQL
• Downloaded
WordPress
Steps 1,2,3
• Added website in IIS
and bound it to HTTP
port 80.
• Added content to
WordPress.
Steps 4,5
• Configure Firewall
• Installed SSL
certificate to secure
theWordPress admin
and bound it to
HTTPS on port 443.
Steps 6,7

Install IIS Server
• Go to Control Panel->Programs
and Features
• In “TurnWindows features on or
off”, select Internet Information
Services and it will install IIS
with default features.
• It will create inetpub/wwwroot
directory.
• Go to browser and type
http://localhost to verify that IIS
server has been installed.

Install PHP
• Download PHP installer for
windows.
• Run the installation setup and follow
the process.
• Verify that PHP is configured and
running on the machine.
• Create a file info.php and put it in
inetpub/wwwroot
• File content is <?php echo phpinfo();
?>
• Browse http://localhost/info.php it
will show PHP information page.

Install MySQL
• Download MySQL installer for
windows.
• Run the installation setup and
follow the process.
• After installation, connect to
MySQL server.

Download WordPress
• DownloadWordPress
• Extract the zip file into
inetpub/wwwroot/IT640
• Open IIS manager and bind the
WordPress on HTTP port 80.
• Create Database using MySQL
database manager.

Install WordPress
• Browse http://localhost and it
will load theWordPress
installation page as HTTP port
80 binds toWordPress
Directory.
• Follow the installation process.
• After installation it will load the
WordPress admin page. Once
logged in admin can add
content.

Configure Firewall
• Go to Control Panel->Windows
Firewall (Turn on the windows
firewall).
• This setting would block all the
connections and requests
including port 80 and 443.
• Add New Rule to allow
connection on ports 80 and 443.

Install SSL
• Create a self-signed certificate
using IIS server.
• Bound the certificate to the
abccompany.com hostname,
using .NET SDK’s makecert.exe.
• After creating the certificate, it
becomes available in IIS and is
ready to be imported by the
website.

Add hostname
• Point local IP address 127.0.01
to abccompany.com, edited
/windows/system32/drivers/etc/
hosts file
• User can access the website at
http://abccompany.com
instead of http://localhost.

Secure WordPress admin
• Configured theWordPress to strictly
use HTTPS while using admin panel
and its login.
• Browser verifies the hostname from
certificate’s “IssuedTo” with the
actual host name in the URL.
• Most of the browsers show the
padlock icon to confirm that identity
has been matched, and this secure
connection starts with
https://abccompany.com
