This document discusses server deployment using cloud servers on OpenShift. It provides steps to create an account, set up SSH keys, create an application with PHP, add MySQL and phpMyAdmin cartridges, and push code to the application. Key benefits of cloud servers over dedicated servers include redundancy, affordability, scalability, and no single point of failure.

1. Server Deployment
BUET SADD

2. Why Server Deployment ??

3. Why use Cloud Servers???
- not Dedicated Servers???

4. Why Cloud Servers???
• Server redundancy
– If a physical server fails, cloud servers can automatically be
switched to other live physical servers.
• Data redundancy
• Affordability
– only pay for the resources that you use
• Scalability
– start with minimum resources and later you can expand
them as per your requirements
– Flexible, easily done using software
• No single point of failure

5. Some Cloud Hosts
• Amazon AWS : http://aws.amazon.com/
• Rackspace Cloud :

7. Deployment In Openshift
Step by Step
• Signup
– Visit https://www.openshift.com/ and signup a free account
– An email will be sent to your given mail address with a link, click that
to activate your account
• Open the Console and Create an Application
– Go to
https://openshift.redhat.com/app/console/application_t
ypes
– You’ll be provided with number of platform options in the
landing page
• PHP, Ruby, Python, Java, Node.js etc
– Choose the one you need
• We will deploy a sample PHP application
– So we choose “PHP 5.3” under “PHP” category

8. • In the landing page we need to provide the Public URL of
your app
– through this URL your application will be accessible to all
– one portion of the url will always be consisting of your username and
“rhcloud”, you need to provide the other part
– Can be changed later
• After providing the public URL, hit “Create Application”

9. • In the landing page you will be provided your
full public url

10. • Openshift uses Git to manage your codebase
– The needed git commands will be provided too
• At first you need to clone the default codebase
into your workstation
– But before that we need to setup a secure connection
by providing SSH key

11. Setting Up SSH Key
• Can be done by software Link given in
resources section
• We will use Git. OH YE !!
• Open git and run the following command
– ssh-keygen -t rsa -C "your_email@example.com"
– Replace your_email@example.com with your own
email address 
– Provide a passphrase
– Your key will be saved in a file “id_rsa“ in a
location similar to this “Your identification has
been saved in /c/Users/you/.ssh/id_rsa.”

12. And you are done with the SSH Key

13. • Now first go to “My Account”
• Under the “Public Keys” section
– Select “Add a new key.”

14. • Copy the content of “id_rsa.pub” file and
paste it to corresponding field
• Provide a name for the key and hit create
• Now we can use Git to manage the codebase

15. • Now go to “My Application” and choose the
corresponding application name

16. • Copy your repository address
• Open git in a folder of your pc and run the
command
– git clone your_repository
• So all the default code in the server is now
cloned/copied into that folder (say folder name is
“Codebase”)

17. • The codes are copied in a folder structure like this
• All the codes will be copied inside a folder named
as your app name - “picpuzzle in our sample
case”
• Inside that folder there is a folder named php
• Copy all your code in that folder
• You may need to change some of the config
variables before uploading like : baseurl,
database name etc

18. • Open git bash in the folder named same to your
project name
• Run the command “git status” in git bash to see if
the files we copied correctly or not
– You should see all the copied files under untracked
files
• Run “git add -A”
• Run git commit –m “Fresh_project”
• The run “git push origin master”
– This should start uploading your codes in the server
• Go to the public url set before, after the push
command finish completes execution

19. Adding Other Functionality
• Most of the time you also need Functionalities
like Database , Cron Job etc.
• Openshift provides this in the form of
cartridges
• Each cartridge provides some functionality
• We will add “MySQL Database” and
“phpMyAdmin” cartridge in our app

20. Adding a cartridge
• Go to your application and hit “Add cartridge”

21. • Select the needed cartridge , for this case
“MySQL”

22. • Then Select “Add cartridge”
• The landing page will contain the needed
credentials : Root User, Root Password,
Database Name
• Save this info for future use

23. • Add phpMyAdmin cartridge like before
• Save all the credentials for future use
– Root User
– Password
– URL :
• follow the URL link to log in to phpMyAdmin
providing the username password

24. • Now you can do your database operations 
• You should use the corresponding IP address
(highlighted in the box – 127.3. ..) as
hostname of database
