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
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.”
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
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
