created and deployed. a rotating wheel next to the “Monitor” button. Once creation
and launch are completed, you will see the wheel turn into a green round circle with a
check mark in the middle.
6
PHP Instance Dashboard
Beside “<YourEnvironment” subtitle there is a URL such as YourAppNameenv.elasticbeanstalk.com, click on it. You should see the "Congratulations" page. If you
see it as shown below, your application and environment have been created properly.
Then go back to Elastic Beanstalk console.
PHP Sample Application
7
6. Upload your PHP application
Develop your PHP server application, and make sure that you name the file index.php.
Compress the file with ZIP so that the resulting file is named index.php.zip. On a Mac,
you can right click the file and choose compress. On Windows, there are several free
programs, such as 7-Zip or FreeZip, etc. that you can use.
From the Elastic Beanstalk console, select your environment and click on the Upload
and Deploy button.
The Upload and Deploy popup will display. Enter a Version label (e.g., version 1.0).
Click on the Choose File button and select the index.php.zip file. Then click on
Deploy button.
Again, wait several minutes for the rotating wheel to finish and the green circle with
checkmark to appear. Click again on the link “YourAppNameenv.elasticbeanstalk.com”. Check that your PHP app is running correctly.
• Important Note: in the future if you want to upload an updated version of
index.php, you should enter a different version label. Otherwise, you will get an
error. It is recommended that you use increasing version numbers (2.0, 2.1, 3.0,
etc.)
To browse how your web service and application has been set up, go to the Services
console (which is in the top menu of Elastic Beanstalk console) and select the Compute
EC2 Service. You should see that you have 1 Running Instance, 1 Volume, 1 Elastic
IP, zero or 1 Load Balancer (managing port 80), and 1 (or 2) Security Groups.
For example, you can type this code and save it as index.php and then compress it as
index.php.zip:
<?php phpinfo();?
After you deploy your code, your website will look like this.
8
7. Set up Exploring Your Instance (Optional)
If you want to explore your Instance and create your own domain-based URL with SSH
control, you can add the following steps.
7.1 Get and Setup SSH
Once the PHP app with SSH-enabled environment is running, you can get access using
SSH. You can use SSH on a Mac running MacOS, or Putty when running on Windows.
On a Mac, SSH is built into MacOS and can be accessed through the Terminal app and
there is no additional setup needed.
On a Windows PC, you will need to download the complete PuTTY distribution at:
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
9
You should download the file putty.zip that contains all the binaries, including
PuTTYgen as see in this snapshot from the website above:
PuTTY needs additional setup as it needs to use a converted version of the private key.
The instructions on how to perform such conversion are available here:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html
The major step is to use PuTTYgen to convert your private key format (.pem) generated
by Amazon EC2 into the required PuTTY format (.ppk).
8.2Create a Key Pair
• From the Services drop down, under the Compute section, select the EC2.
10
• Under NETWORK AND SECURITY select Key Pairs.
• Click on the button Create Key Pair.
• Enter a name like phphosts (you must have your own random name!) and
click on Create.
• A download of your private key should start automatically. Save the key, like
phphosts.pem, in an appropriate location.
8.2.1 Associate your Instance to the Key Pair
• You now need to associate your Instance with the just created key pair.
• Select the Elastic Beanstalk under Services.
• Select your application environment, but clicking anywhere in the “green”
rectangle.
• Click on Configuration on the left menu.
• Click on the settings wheel next to Instances.
• Select the key pair you just created for the EC2 key pair field. Click Refresh.
11
• Hit Apply and then Save and wait for a few minutes for the configuration
changes to take place. You may get INFO, WARN and sometimes SEVERE
messages during this time. Wait until the update of the environment has
completed, and Health is back to Ok.
• Go back to your EC2 instance after some time and check under Key Name, you
should now see your associated key pair.
8.3 Open port 22
To open port 22, which is needed by SSH, follow these steps:
1. In the EC2 Management Console, click on Instances.
2. Under NETWORK & SECURITY, click on Security Groups.
3. Select the security group (present as a link) configured for your instance.
4. For the security group, edit the "Inbound rules" (Inbound tab present on the bottom
of the pane) by clicking the Edit button.
5. Add a new rule for Type = SSH, Protocol = TCP, Port Range = 22, Source =
Custom 0.0.0.0/0. Click Save.
8.3.1 Errors when Connecting
If you fail to either open port 22 or associate your instance to a key pair, you will get an
error popup when you try to Connect to Your Instance using EC2 Dashboard
INSTANCES Instances select instance Connect, as show in the picture below.
12
8.4 Access your Linux Instance with SSH
• To see how to launch your SSH client go to Services and select EC2.
• Under the INSTANCES section in the navigation pane on the left, select
Instances.
• Select your instance in the table (the check box turns blue) and select the
Connect button next to Launch Instance.
• The Connect To Your Instance popup will display. Select the radio button A
Standalone SSH Client. Notice the hyperlink “connect using PuTTY” (see
section 7.4.2). See the snapshot below, showing Elastic IP connection string.
8.4.1 Mac running OS X / ssh
Change the permission of phphosts.pem first:
chmod 400 phphosts.pem
13
On a Mac you will need to enter a command like this one (when using Public DNS):
ssh -i phphosts.pem ec2-user@ec2-54-235-60-138.compute1.amazonaws.com
or this one (when using Elastic IP)
ssh -i phphosts.pem ec2-user@204.236.235.251
type yes, when asked. Make sure that you are executing the ssh command in the same
folder that contains the key. You should see output like this one (using Public DNS):
$ ssh -i "phphosts.pem" ec2-user@ec2-204-236-235-251.compute1.amazonaws.com
